What Is Healthcare Fraud?

Healthcare fraud refers to conduct where a provider, practice, facility, or individual allegedly obtains payment or benefits through false, misleading, or improper claims submitted to government healthcare programs such as Medicare, Medi‑Cal, TRICARE, Veterans Affairs, or other public or private payors.

It is treated as a serious white‑collar crime because it impacts billions of dollars of public funds and triggers enforcement under multiple federal and state statutes, including:

• The Federal False Claims Act (FCA) — civil liability for false claims, treble damages, and per‑claim penalties. 

• Anti‑Kickback Statute (AKS) — prohibits remuneration tied to referrals or billing for services. 

• Stark Law — civil penalties for improper physician self‑referrals.

Healthcare fraud can include: upcoding, unbundling, phantom billing, kickbacks, false diagnoses, medically unnecessary services, duplicate claims, and misrepresentations about treatment or equipment.

We Handle Federal Cases Only. Here Is Exactly What That Means.

Most firms are vague about scope because they want every call. We are not, because in California the difference between a federal and a state case changes your exposure, your courthouse, your timeline, and which lawyer you should hire.

The 30-second test: which government is coming for you?

We defend: federal grand jury investigations and indictments · 18 U.S.C. §§ 1347, 1349, 1035 charges · Anti-Kickback and EKRA charges · civil False Claims Act and qui tam defense · Civil Investigative Demands · HHS-OIG, FBI, DEA, DCIS, and IRS-CI subpoenas · Medicare payment suspensions · Medicare enrollment revocations · OIG exclusion · federal contract suspension and debarment.

We do not handle: California Attorney General DMFEA prosecutions · county district attorney cases under Cal. Penal Code § 550, Welf. & Inst. Code § 14107, or Ins. Code § 1871.4 · California False Claims Act claims · Medical Board, Dental Board, Board of Pharmacy, or nursing board discipline · California workers’ compensation fraud · private payer disputes · malpractice.

The Medi-Cal trap nobody explains

Medi-Cal is funded jointly by California and the federal government. That means the same billing conduct can be charged either way. A U.S. Attorney can charge Medi-Cal billing under 18 U.S.C. § 1347 or the federal False Claims Act because federal dollars fund the program. The California Attorney General can charge it under state law. Both can happen at once.

Providers lose weeks calling the wrong kind of firm. If you are not sure which you have, call and read us the caption. 1-866-601-5518. It takes five minutes and we will tell you honestly if you need a different firm.

If you have both a federal case and a state license matter, you need federal counsel and California license counsel working together — because what you say in one is usable in the other. We handle the federal side and coordinate.

The First 72 Hours: What To Do and What Not To Do

Most of the damage in a federal health care fraud case happens in the first three days. It is almost always done by the provider, not the government.

Hours 0–2: Agents are in your building

Hours 2–24: Stop the bleeding

Do:

• Issue a written litigation hold immediately. Suspend automatic email deletion, EMR purge cycles, voicemail deletion, and text auto-delete on company phones. Put it in writing and date it.
• Designate one point of contact for all government communication — counsel.
• Identify who needs their own lawyer. If an owner, medical director, or compliance officer has individual exposure, that conflict has to be surfaced now, not in month six.
• Preserve the claims data. Pull and lock down the billing files, the clearinghouse records, and the remittance advices before anything is overwritten.
• Tell your employees in writing that they may speak to investigators or decline, that counsel is available to them, and that the company will not retaliate.

Do not:

• Do not touch a single record. Not to correct it. Not to complete it. Not to “clean up” a chart that was always sloppy. A late addendum to a medical record is the single most damaging document in a health care fraud trial.
• Do not delete texts, emails, or messages. Ever. Under any circumstance. 18 U.S.C. § 1519 carries 20 years.
• Do not fire the employee you suspect is the whistleblower. 31 U.S.C. § 3730(h) makes retaliation its own claim, and it converts a defensible case into a sympathetic one.
• Do not have your regulatory lawyer respond. The attorney who wrote your compliance manual is valuable — and may become a witness. This is a different job.
• Do not let one lawyer represent the company and every individual. Interests diverge fast, especially if the company later cooperates.

Hours 24–72: Get ahead of it

Do:

• Run a privileged internal review — directed by outside counsel, scoped to the actual allegation, not to everything.
• Reconstruct the record before you produce anything. Pull the claims data against the clinical documentation. Know your own weak spots before the government tells you about them.
• Calendar every deadline. CID return dates, subpoena return dates, payment suspension rebuttal windows, and revocation reconsideration deadlines are short and they are not routinely extended for you.
• Check your enrollment and payment status. If Medicare has stopped paying you, that is a separate proceeding with its own clock. See below.
• Notify your carrier. Most professional liability and D&O policies have regulatory or government investigation coverage with notice conditions. Late notice forfeits it.

Do not:

• Do not self-disclose yet. Disclosure can be the right move. It is never the right move before you know what you actually have.
• Do not call the payer, the MAC, or the UPIC to “sort it out.” Those calls are documented and produced.
• Do not post about it, discuss it on a group text, or tell your practice manager the theory of the defense. Neither is privileged.
• Do not assume silence means it went away. Sealed qui tam cases run for years. Quiet is not the same as over.

If you are inside this window right now, stop reading. Call our California healthcare fraud defense lawyers 1-866-601-5518.

How Do I Know If I’m Under Federal Investigation?

This is one of the most-searched questions by health care providers, and the honest answer is that you usually find out indirectly. These are the signs:

1. Your employees are being contacted at home. Agents approach billers, medical assistants, marketers, and former staff in the evening, at their doors, without counsel. If two of your people mention it, you are the subject.
2. A former employee lawyered up and went quiet. Especially one who complained about billing before they left.
3. You received a UPIC, ZPIC, or RAC audit that is unusually broad — a large sample, a long lookback, or a request for records rather than claims data.
4. Your Medicare payments stopped or dropped without an explanation. See the payment suspension section below.
5. Your bank asked odd questions, or an account was frozen. IRS-CI and financial intelligence review often precede contact.
6. A vendor, lab, or referral partner tells you they got a subpoena that lists your name or NPI.
7. A patient tells you an investigator called them about services you provided.
8. Your practice’s records were requested by a party you do not recognize.
9. You received a target letter, a subject letter, or a grand jury subpoena. This one is not a sign. This is notice.

One thing that is not a reliable sign: hearing nothing. Federal health care fraud investigations commonly run one to three years before a charging decision, and sealed qui tam cases run longer. Silence is often the middle of the case, not the end of it.

If two or more of these are true, get counsel now. 1-866-601-5518.

What Document Did You Receive? Find It Here.

The piece of paper in your hand tells you where you are in the case. Each one means something different and each one has a different right answer.

What is a target letter, and what does it look like?

A target letter is a letter from a U.S. Attorney’s Office telling you that you are a target of a federal grand jury investigation — meaning prosecutors believe there is substantial evidence linking you to a crime. It typically arrives by mail or is hand-delivered by an agent, on U.S. Attorney’s Office letterhead, and it usually: identifies the statutes under investigation, states that you are a target, advises you of your right to counsel and your Fifth Amendment rights, and invites you or your attorney to contact the office.

Target vs. subject vs. witness: A target is someone the government believes committed a crime. A subject is someone whose conduct is within the scope of the investigation. A witness has information. Letters use these words deliberately. The word in your letter matters enormously.

How long after a target letter until an indictment? There is no fixed period. Weeks to many months is typical. But a target letter is frequently an invitation — the government is signaling that it is willing to hear from you before charging. That window is the single most valuable opportunity in the entire case, and it closes.

What to do: Do not respond yourself. Do not call the AUSA. Do not accept an invitation to be interviewed. Get counsel, who will make contact, learn what they can about the theory, and decide whether a pre-indictment presentation is the right move.

What is a grand jury subpoena, and can I refuse it?

A federal grand jury subpoena compels either documents (subpoena duces tecum) or testimony (subpoena ad testificandum). It will name a return date and a U.S. District Court.

Can you refuse it? No. Ignoring a grand jury subpoena risks contempt. But that is not the same as complying with it as written. Scope, custodians, date ranges, format, and timing are all negotiable with the prosecutor through counsel, and privilege objections must be asserted properly and on time.

Are grand jury subpoenas confidential? Grand jury proceedings are secret under Federal Rule of Criminal Procedure 6(e), and that obligation binds the government — not you. Recipients are generally not prohibited from disclosing that they received one unless the subpoena or a court order says otherwise. Prosecutors often request that you not disclose it. A request is not an order, and how you handle that request is a strategic decision.

A subpoena for records is different from a subpoena to testify. If you personally are called to testify and you have exposure, the Fifth Amendment is available to you. Individuals can assert it. A corporation cannot — and the custodian of corporate records generally cannot refuse to produce them on Fifth Amendment grounds. This distinction traps people.

See US Supreme Court Case Showing That If You Did Not Actually Believe You Defrauded the Government, You May Have a Chance at Prevailing.

What is a Civil Investigative Demand?

A CID is compulsory process issued under 31 U.S.C. § 3733 in a civil False Claims Act investigation. It can demand documents, written interrogatory answers, and oral testimony.

What it usually means: In most cases a CID signals that a qui tam complaint has been filed under seal and the government is investigating to decide whether to intervene. You are typically not told the relator’s name or the allegations.

Why it is more dangerous than it looks: A CID is a civil instrument, but everything you produce is available to a parallel criminal investigation. Treating a CID as a routine records request is how civil exposure becomes an indictment.

What to do: Do not simply produce what it asks for. Scope and timing are negotiated with DOJ through counsel. And understand that the sealed period is when you have the most influence over whether the government intervenes at all.

What is an HHS-OIG subpoena?

An administrative subpoena issued under 42 U.S.C. § 405(d)/(e) or the Inspector General Act. It demands documents and does not require a grand jury. It is frequently the first formal step in a health care fraud matter and often runs alongside a criminal investigation. Same rules: negotiate scope, preserve everything, produce nothing without counsel’s review.

What if agents executed a search warrant?

A search warrant means a federal magistrate judge found probable cause. This is a serious escalation — it means the government did not think a subpoena would produce honest results.

What to do that day: Get a copy of the warrant and the inventory. Note what was seized and from where. Identify what was taken that is privileged — patient files, counsel communications — and raise it immediately; taint protocols exist and must be invoked early. Do not discuss the case in the office. Assume that devices, servers, and phones are now in the government’s hands.

Medicare stopped paying me and nobody charged me with anything. What is that?

A payment suspension under 42 C.F.R. § 405.371. CMS can suspend Medicare payments in whole or in part on a credible allegation of fraud — a standard far below probable cause, with no requirement that you have been charged with anything. It frequently begins before you are notified.

There is a rebuttal process with a short deadline, and it is one of the few moments where a well-supported written submission can restore cash flow. This is its own proceeding with its own clock. Do not wait for the criminal case to develop.

A UPIC or MAC audit with an extrapolated overpayment

An extrapolated overpayment demand takes an error rate from a small sample and applies it to your entire claims universe. A 40-claim sample can produce a seven-figure demand. These have appeal rights on a strict timeline — redetermination, reconsideration, ALJ hearing, Medicare Appeals Council — and the sampling methodology itself is challengeable. An audit is also frequently the front end of a fraud referral, which is why the response should be prepared with that possibility in mind.

The 12 Mistakes That Destroy Health Care Fraud Defenses

We see the same avoidable errors over and over. Each one below has ended a case that was otherwise winnable.

1. Talking to agents to be helpful. A statement you believe is true, that turns out not to be, is a separate five-year felony under 18 U.S.C. § 1001 — independent of the underlying conduct. People are convicted of § 1001 in cases where the government could never have proven the fraud.

2. “Fixing” a chart. Late entries, addenda, and corrections made after notice are the government’s best exhibit. Metadata shows when it was written. A sloppy contemporaneous record is defensible. A record improved after the subpoena is not.

3. Deleting anything. Emails, texts, voicemails, Slack, the marketer’s WhatsApp thread. 18 U.S.C. § 1519 carries 20 years — more than the underlying health care fraud charge in most cases.

4. Letting the compliance officer run the internal investigation. Without outside counsel directing it, the work product is often not privileged, and the interview memos become discovery for the government.

5. Firing the suspected whistleblower. It creates an independent retaliation claim under 31 U.S.C. § 3730(h) and hands a jury a sympathetic narrative.

6. Using one lawyer for the entity and every individual. The entity’s interest and the physician’s interest diverge the moment cooperation is discussed. Sort this out in week one.

7. Responding to a CID by producing everything it asks for. Overbroad production creates problems that cannot be undone, and hands the criminal side a roadmap.

8. Ignoring the administrative track. Payment suspension, revocation, and exclusion run on separate, faster clocks. Providers who focus entirely on the indictment lose the practice while winning the case.

9. Self-disclosing before you know what you have. Disclosure can cut treble damages to double under 31 U.S.C. § 3729(a)(2). It can also build the government’s case for them. The sequence is: investigate under privilege, then decide.

10. Assuming a billing company’s errors are the billing company’s problem. The claim was submitted under your NPI, with your certification. Vendor error is a defense to intent, not a shield from liability.

11. Talking to the contracting officer, the MAC, or the payer to smooth it over. Once an OIG or DOJ file is open, nobody at the payer can make it go away, and those calls become evidence.

12. Waiting to hire counsel until charges are filed. The most valuable work in a health care fraud case happens before an indictment — declinations, civil-in-lieu-of-criminal resolutions, narrowed charges. After indictment, that range of outcomes is largely gone.

What Charges Can Be Brought Against You Criminally?

Federal health care fraud is rarely charged alone. A typical California indictment stacks several of these.

Is health care fraud a felony?

Yes. Every charge in the table above is a federal felony.

Three things about that table that surprise people

The obstruction charge is usually worse than the fraud charge. Section 1519 carries 20 years. Section 1347 carries 10. Providers who panic and clean up records routinely face more exposure for the cleanup than for the billing.

The Anti-Kickback Statute is criminal, not just civil. Many providers think of AKS as a regulatory matter handled by lawyers and compliance consultants. It is a 10-year felony. And it does not apply only to physicians — it reaches anyone who solicits, receives, offers, or pays remuneration, including marketers, lab sales reps, and owners.

EKRA is the trap in California lab, toxicology, and addiction treatment cases. Unlike AKS, 18 U.S.C. § 220 applies to all health care benefit programs — including commercial insurance. Sales compensation structures built to satisfy AKS safe harbors, and that deliberately exclude federal program business, can still violate EKRA. California’s SUD treatment and clinical toxicology sectors have been a repeated federal focus.

What sentence would I actually face?

Statutory maximums are not sentences. Federal sentences in health care fraud cases are driven primarily by the loss amount under U.S.S.G. § 2B1.1, plus enhancements for the number of victims, sophisticated means, abuse of a position of trust (which applies to licensed professionals), and role in the offense.

Why that matters more than anything else in the case: the government’s opening loss figure is usually the total amount billed, not the amount improperly paid. The difference between those two numbers can be the difference between probation and years in custody. Contesting the loss calculation is often the highest-value work in the entire defense.

What Can Happen to You Civilly?

The civil case can cost more than the criminal case. It is a separate proceeding, and it can run at the same time on the same facts.

Is the False Claims Act civil or criminal?

The False Claims Act (FCA) 31 U.S.C. §§ 3729–3733, is civil. But the same conduct can be charged criminally under § 1347 or § 287, and DOJ’s Civil and Criminal Divisions coordinate. A civil settlement does not foreclose criminal charges.

What does the government have to prove?

Much less than in the criminal case, and this is the single most misunderstood point in health care compliance.

Under 31 U.S.C. § 3729(b)(1), “knowingly” means actual knowledge, deliberate ignorance, or reckless disregard — and the statute expressly requires no proof of specific intent to defraud. The burden of proof is a preponderance of the evidence, not beyond a reasonable doubt.

Translation: the government does not have to prove you meant to cheat anyone. A coding practice nobody reviewed for three years, a certification signed by someone who never checked, an audit finding that was never corrected — these produce False Claims Act liability at organizations where no one intended to defraud anybody.

What is the penalty for violating the federal False Claims Act?

Those are the inflation-adjusted figures currently in effect. DOJ did not issue a 2026 adjustment — an appropriations lapse prevented publication of the underlying CPI data — so the 2025 levels remain operative.

Why “per claim” is the number that should worry you

The penalty attaches to each claim, not to each contract or each health care fraud investigation. In health care, a claim is a single line on a single bill.

Worked example. A practice submits 400 claims per month. The government alleges a two-year period.

• 400 × 24 = 9,600 claims
• At the $14,308 minimum: approximately $137 million in penalties
• Treble damages are then added on top

That is why False Claims Act exposure in provider cases routinely dwarfs the government’s actual loss by an order of magnitude — and it is why the constitutional excessiveness of aggregate penalties is a live defense issue, and why fighting over the number of claims matters as much as fighting over liability.

Other civil and administrative money exposure

• Civil Monetary Penalties Law, 42 U.S.C. § 1320a-7a — separate penalties per item or service, plus assessments of up to three times the amount claimed
• Stark Law, 42 U.S.C. § 1395nn — strict liability. No intent required at all. A technically defective physician compensation arrangement creates a refund obligation and FCA exposure even where everyone acted in good faith
• Overpayment refund obligation — identified overpayments must be reported and returned within 60 days; a retained overpayment is itself a “reverse false claim”
• Forfeiture and restitution in the criminal case

How far back can they go?

A civil FCA action must be brought within six years of the violation, or three years after the material facts were known or reasonably should have been known by the responsible government official — but never more than ten years after the violation. Whichever is later controls.

Practically: conduct from 2019 can still be actionable today. Closing a practice, selling it, or changing billing companies does not end exposure.

And Then There Is the Part That Actually Closes Practices

Providers fixate on prison and penalties. The thing that ends careers is losing the right to bill.

There is a reason providers search for a healthcare enforcement action defense attorney rather than just a criminal lawyer. An enforcement action is not one case. It is up to four, running on separate tracks, in separate forums, with lower standards of proof and faster clocks than the criminal case — and any one of them can end the practice while the indictment is still pending:

Medicare payment suspension — 42 C.F.R. § 405.371. Imposed on a credible allegation of fraud. No charge required. Cash flow stops within days.

Medicare enrollment revocation — 42 C.F.R. § 424.535. More than twenty grounds, including a felony conviction within ten years and — critically — “abuse of billing privileges,” meaning a pattern or practice of claims that fail to meet Medicare requirements. No conviction required. Carries a reenrollment bar of one to ten years, extendable to twenty for a second revocation.

OIG exclusion — 42 U.S.C. § 1320a-7. Exclusion is mandatory upon conviction of a program-related crime, patient abuse, a health care fraud felony, or a felony controlled substance offense. Minimum five years. Permissive exclusion under § 1320a-7(b) reaches further, including misdemeanors. An excluded provider cannot bill Medicare, Medicaid, TRICARE, or the VA — and cannot be employed by anyone who does.

Suspension and debarment — FAR subpart 9.4. If your organization holds federal contracts or grants — VA Community Care, TRICARE, IHS, BOP, or HRSA funding — a suspension and debarment official can act on adequate evidence, before any charge or finding, and stop new awards immediately.

The number nobody reports from the 2026 takedown

When DOJ announced the June 2026 National Health Care Fraud Takedown, the headline was 455 defendants and $6.5 billion. The numbers that mattered more to providers:

• 1,079 providers suspended from Medicare
• 1,403 providers’ billing privileges revoked
• 1,400+ provider exclusions
• 928 DEA administrative actions against controlled substance authority since October 1, 2025

Most of those providers were never criminally charged.

Why this changes how a plea is evaluated

A plea that looks favorable on its face can end a career if it triggers mandatory exclusion. The charge of conviction, not just the sentence, determines the collateral consequence. Any plea discussion in a provider case that does not account for exclusion, revocation, and licensure is malpractice waiting to happen.

This is where our firm is built differently. Watson & Associates is a federal government contracts and federal program law firm — suspension and debarment, mandatory disclosure, and federal program eligibility are our core practice, applied here to health care. Most criminal defense firms refer the exclusion problem out, or get to it after the criminal case ends, by which point the record is made and the deadlines are gone. Most health care regulatory firms can handle an enrollment appeal but cannot sit across from an Assistant U.S. Attorney. A healthcare enforcement action defense attorney has to be able to do both, at the same time, without the position taken in one proceeding destroying the position needed in another. We run both tracks with one team from week one.

Ask any firm you interview how they handle the exclusion and revocation track. Then call us. 1-866-601-5518.

What Defenses Actually Work in These Cases?

Not a list of theories. These are the arguments that move federal health care fraud cases.

The loss amount is wrong. The government starts with the amount billed. The correct figure is the amount improperly paid, net of services actually rendered and properly billed. This single fight drives the sentence, the restitution, the forfeiture, and the FCA damages.

The claim count is wrong. Per-claim penalties multiply. Narrowing the universe of claims — by date range, by payer, by service line, by identifying claims that were correct — reduces exposure faster than any other argument.

There was no intent, and the record shows it. Under Schutte v. SuperValu, 598 U.S. 739 (2023), FCA scienter turns on what the defendant subjectively believed. That cuts both ways honestly: it kills the after-the-fact “any reasonable reading” defense, but it makes contemporaneous evidence powerful — documented coding guidance, billing questions escalated and answered, a prior audit finding actually corrected, a compliance program that was used rather than shelved.

The requirement was genuinely ambiguous. Medicare coverage rules, LCDs, and manual provisions are frequently unclear. Falsity requires an objectively identifiable requirement that was breached.

Materiality under Escobar. Would the government have paid had it known? If the payer continued paying after learning the relevant facts, materiality is contestable.

The kickback did not cause the claim. See the Ninth Circuit section below — this is open ground in California.

Government knowledge. Where the agency or contractor knew of and accepted the practice, both scienter and materiality are weakened.

The statistical extrapolation is invalid. Sample size, sample selection, and stratification are all attackable, and a successful challenge can reduce a seven-figure demand to the sampled claims alone.

Rule 9(b). FCA complaints must plead fraud with particularity — the who, what, when, where, and how of specific false claims. Many qui tam complaints do not.

The conduct is outside the limitations period.

What Is Different About a California Federal Health Care Fraud Case?

California’s four federal districts sit in the Ninth Circuit. Ninth Circuit law — not the generic national summary on most defense websites — governs what the government must prove against you. Three points matter, and they cut in different directions.

1. In California, a doctor’s clinical judgment can be “false”

In Winter ex rel. United States v. Gardens Regional Hospital & Medical Center, 953 F.3d 1108 (9th Cir. 2020), the Ninth Circuit held that a certification of medical necessity is not immune from FCA liability merely because it is an opinion. The court rejected an “objective falsehood” requirement: a subjective opinion can be false if it implies facts that do not exist, or if it is not honestly held.

Why this matters to you. In the Eleventh Circuit, providers argue with some success that a difference of clinical opinion cannot be fraud. In California that argument is significantly weaker. A relator can reach a jury on medical necessity with expert testimony that the certification was unsupported by the record.

The practical consequence for hospice, home health, inpatient admissions, wound care, and behavioral health providers in California: the contemporaneous documentation is the defense. Not what the physician remembers. Not what the physician would say now. What the chart showed at the time of certification. This is why an early privileged reconstruction of the clinical record — before any production — is worth more in a California case than almost anywhere else.

2. On kickback causation, the Ninth Circuit has not ruled — and that is an opportunity

The False Claims Act treats a claim “resulting from” an Anti-Kickback Statute violation as false. Courts disagree about what “resulting from” requires.

The government’s usual position is that a remuneration arrangement taints every claim submitted during the period. Under a but-for standard it must show the claims would not have been submitted absent the arrangement — a far harder burden that can collapse the claim count, and with it the damages and per-claim penalties.

Because the Ninth Circuit has not resolved it, this is live, arguable ground in every California district court. It is also the kind of argument that gets waived by counsel who did not know to make it.

Where We Defend Health Care Providers in California

Federal health care fraud cases are prosecuted in four California districts. Which one you are in matters — enforcement priorities, charging practices, and how much pre-indictment access you get differ meaningfully between them.

Southern California: Los Angeles, Orange County, San Diego, and the Inland Empire

Southern California is the most active federal health care fraud enforcement region in the United States, and a Southern California healthcare fraud defense lawyer is dealing with two very different U.S. Attorney’s Offices.

Central District of California — Los Angeles, Santa Ana, Riverside. The largest federal district in the country by population and among the most active health care fraud districts anywhere. Sustained focus on hospice, home health, DME, clinical laboratories, and telehealth. In the June 2026 takedown, C.D. Cal. defendants were charged in a $27.7 million hospice scheme built on kickbacks paid to a funeral home employee for deceased beneficiaries’ information, and a Whittier defendant was charged in connection with nearly $270 million in fraudulent Medi-Cal prescription drug claims.

If you are looking for a Los Angeles healthcare fraud lawyer, understand what you are hiring for: the Central District charges more provider cases than most districts see in a decade, its prosecutors are specialists, and the volume means pre-indictment presentations have to be sharper and shorter than they would be elsewhere. The same is true for Orange County providers charged in Santa Ana and Inland Empire providers charged in Riverside — same district, same office, same practices.

Southern District of California — San Diego, El Centro. Home of the Major Frauds Section where our California lead, Carolyn L. Oliver, served as an Assistant U.S. Attorney. Border-region matters, cross-border pharmacy and DME schemes, and military and TRICARE-adjacent provider cases appear here more than elsewhere in the state. Our San Diego office is at 402 West Broadway, Suite 400.

Northern California: San Francisco, Oakland, San Jose, and Silicon Valley

Northern District of California — San Francisco, Oakland, San Jose, Eureka. This is now the California home of the DOJ West Coast Health Care Fraud Strike Force, announced April 30, 2026, deploying at least 10 additional federal prosecutors alongside HHS-OIG, the FBI, and the DEA, with named priorities in hospice, sober homes, and wound care.

If you need a San Jose healthcare fraud defense lawyer or counsel in San Francisco or Oakland, this is the single most important thing to know: the office reviewing your billing data now has prosecutors whose entire assignment is your industry, and they are not working through a backlog of unrelated cases. Northern California also carries a distinct digital health exposure — telehealth platforms, health tech companies, diagnostics startups, and the physician networks they contract with — where the government’s theory is frequently about physician review time, standing orders, and referral volume rather than traditional billing.

Central Valley and Northern Interior: Sacramento, Fresno, Bakersfield, Redding

Eastern District of California — Sacramento, Fresno, Bakersfield, Redding. Active rural health, hospice, home health, pharmacy, and long-term care enforcement, often involving critical access hospitals, FQHCs, and rural provider networks where the federal funding stream itself creates additional exposure.

And everywhere else

Federal health care fraud is federal law, applied the same way in every district. We appear in federal district courts nationwide. Where the case is charged changes the strategy, not our ability to handle it.

What Changed in Federal Enforcement in 2026

Three developments explain why California providers are seeing more activity this year.

DOJ built a new Fraud Division and pointed a strike force west. The Justice Department created a National Fraud Enforcement Division on April 7, 2026. On April 30, it announced the West Coast Health Care Fraud Strike Force covering the Northern District of California, Nevada, and Arizona.

Cases now start with data, not whistleblowers. DOJ’s Health Care Fraud Data Fusion Center — staffed by the Health Care Fraud Unit, HHS-OIG, the FBI, and others — applies data analytics and financial intelligence to billing data across programs to identify anomalies and geographic hot spots. You can now be under federal health care fraud investigation without anyone ever having complained about you. If your utilization is an outlier for your specialty and geography — high-level E/M codes, skin substitute applications, hospice length of stay, urine drug testing panels, telehealth volume — you are visible whether or not you did anything wrong.

The civil side hit a record. For fiscal year 2025, DOJ reported $6.8 billion in False Claims Act settlements and judgments — the highest ever — with over $5.7 billion (about 84%) from health care. Whistleblowers filed 1,297 qui tam suits, breaking the prior record, and the government opened 401 investigations of its own.

How We Defend a Federal Health Care Fraud Case

1. Contain. Litigation hold. One point of contact. Written employee guidance. Conflict screening. An immediate stop to informal contact with agents, the payer, the MAC, and the UPIC.

2. Learn our own case first. Under privilege, we reconstruct the billing record, the clinical documentation, the coding decisions and who made them, the referral and compensation arrangements, the compliance history, and prior audits. In most matters the government’s theory has a factual weak point that only appears when you read the records against the claims data. We would rather find it than be told about it.

3. Answer the demand precisely. CIDs and subpoenas are negotiated, not obeyed. Scope, custodians, date ranges, privilege, and format are all in play — and how a response is framed communicates a great deal about the strength of your position.

4. Defend billing and enrollment in parallel. Payment suspension rebuttal, revocation reconsideration, exclusion advocacy, and — where federal contracts or grants are at stake — a present-responsibility showing to the suspension and debarment official. These deadlines do not wait for the criminal case.

5. Engage the decision-makers before charging. For civil matters, the AUSA and DOJ Civil Fraud attorneys are deciding whether to intervene in a sealed qui tam. For criminal matters, the prosecutor deciding whether to charge and whom. Pre-charge presentations resolve more provider cases than motions do.

6. Litigate when litigation is right. Rule 9(b), Escobar materiality, SuperValu scienter, ambiguity, kickback causation, extrapolation challenges, loss calculation, and constitutional challenges to aggregate penalties.

The Lead Federal Attorneys Who Would Handle Your Case

Carolyn L. Oliver — Of Counsel, California Lead

Carolyn Oliver spent her government career as an Assistant United States Attorney in the Major Frauds Section of the U.S. Attorney’s Office for the Southern District of California — the office that prosecutes federal health care fraud in San Diego and Imperial Counties.

As a federal prosecutor she investigated and tried health care fraud, procurement fraud, securities fraud, bank fraud, mail and wire fraud, and money laundering, handling complex multi-defendant matters involving executives and health care professionals, working with the FBI, IRS-Criminal Investigation, HHS-OIG, and DCIS. She has more than 40 years of legal experience and extensive federal jury trial experience as lead counsel. B.S., Boston University; J.D., Temple University School of Law.

What that gives you: when we assess whether a pre-indictment presentation will land with a California AUSA, that judgment comes from someone who spent years receiving them in a California federal district — who knows how a Major Frauds unit evaluates a provider case, what makes a supervisor decline, and what a case agent needs to hear.

Chris Mancini — Of Counsel, Federal White Collar Defense

Chris Mancini Federal White Collar Criminal Defense Attorney Chris Mancini served as an Assistant U.S. Attorney from 1979 to 1987, rising to Deputy Chief of both the Major Crimes/Environmental Task Force and the Civil Division, supervising 30 attorneys handling money laundering, white collar fraud, and major federal felonies.

He has been in private federal defense practice since 1987 — nearly four decades — covering health care and Medicare fraud, Anti-Kickback matters, False Claims Act defense, procurement fraud, and Civil Investigative Demands. He has taught at the Miami-Dade Police Academy and the Federal Law Enforcement Training Center. B.A. and J.D., Marquette University.

What that gives you: he supervised both the criminal and civil sides of a U.S. Attorney’s Office. When a CID and a grand jury investigation are running on the same facts, that is an unusual and specific advantage — he has seen how the two sides of the office actually coordinate.

Theodore P. Watson — Founder and National Practice Leader

Theodore Watson founded Watson & Associates, LLC and leads the firm’s national federal practice. Before law, he spent more than two decades in federal procurement, including service as a Department of Defense procurement official. He is admitted to practice before the Supreme Court of the United States and leads the firm’s federal government contracts practice — suspension and debarment, mandatory disclosure, procurement fraud, and federal program eligibility.

What that gives you: the exclusion, revocation, payment suspension, and debarment track is not a side service. It is the firm’s core competence, applied to health care. For a provider organization holding VA Community Care, TRICARE, IHS, or HRSA-funded contracts, that combination is hard to find in one firm.

Questions California Healthcare Providers Ask Us

Should I talk to federal agents if they show up at my practice?

No. Say: “I’m not going to answer questions today. My attorney will contact you.” That is not evidence of guilt — it is what every experienced federal lawyer in the country would tell you to say. Agents do not record these interviews; they write a report afterward, and that report becomes the government’s version of what you said. An inaccurate statement is a separate five-year felony under 18 U.S.C. § 1001.

Can a billing or coding error become a federal crime?

Errors are not crimes. Criminal health care fraud under § 1347 requires a knowing and willful scheme — though under § 1347(b) the government need not prove you knew the statute existed. The real risk is a pattern: an error flagged in an audit, never corrected, and repeated. That is the fact pattern from which the government argues knowledge. And civilly, the FCA reaches deliberate ignorance and reckless disregard with no specific intent required. The decisive question in most provider cases is not whether an error occurred — it is what you did after you learned about one.

How long does a federal health care fraud investigation take?

Commonly one to three years from the first subpoena to a charging decision. Sealed qui tam matters often run longer. That time is not dead time — it is when the record is built, when the government’s theory hardens or breaks, and when the pre-charge presentation is made. Providers who treat the quiet stretches as good news usually lose ground during them.

Am I personally exposed, or just my company?

Both are possible and they are separate questions. Federal prosecutors charge individuals — the June 2026 takedown included 90 doctors and other licensed professionals. Corporate form does not shield someone who participated in the conduct. If you are an owner, medical director, or compliance officer, assume you have personal exposure until counsel tells you otherwise, and be careful about relying only on company counsel.

Can my company’s lawyer represent me personally too?

Often not. Corporate counsel represents the entity, and the entity’s interests and yours can diverge sharply — especially if the company later cooperates. Sorting out representation and Upjohn warnings early protects everyone. We routinely coordinate with separate individual counsel in multi-defendant matters.

Can a case be resolved before an indictment?

Frequently, and that is where the most valuable work happens. Declinations, civil resolutions in lieu of criminal charges, non-prosecution and deferred prosecution agreements, and narrowed charging decisions all occur pre-indictment. Once an indictment is returned, the range of outcomes narrows considerably. The earlier counsel is engaged, the more of that range is still available.

Should I self-disclose to OIG or the government?

Sometimes — but never before you know what you actually have. Note that under 31 U.S.C. § 3729(a)(2) a court must assess double rather than treble damages where a person disclosed all known information within 30 days of learning of it, fully cooperated, and did so before any investigation or action had commenced. That window closes permanently once an investigation is underway. Disclosing prematurely, or disclosing the wrong thing, can build the case against you. Investigate under privilege first, then decide.

An employee filed a qui tam case against my practice. What changes?

The complaint is sealed while the government investigates and decides whether to intervene, and you may never be told it exists — a CID or subpoena is often the first sign. The sealed period is your best opportunity: a well-supported presentation to the government during its investigation is how intervention decisions are shaped, and it is not available after unsealing. It also raises immediate employment questions, because 31 U.S.C. § 3730(h) makes retaliation against the relator its own liability. See our False Claims Act whistleblower and retaliation defense practice.

Will I lose my ability to bill Medicare even if I am not convicted?

Possibly. CMS may revoke enrollment under 42 C.F.R. § 424.535 for abuse of billing privileges — a pattern of claims failing to meet Medicare requirements — with no conviction and a reenrollment bar of one to ten years. Conversely, if you are convicted of a health care fraud felony, exclusion under 42 U.S.C. § 1320a-7(a) is mandatory for at least five years.

Do you handle Medi-Cal fraud cases?

We handle federal cases involving Medi-Cal claims — a U.S. Attorney can charge Medi-Cal billing under § 1347 or the federal False Claims Act because Medi-Cal is federally funded. We do not handle prosecutions brought by the California Attorney General’s Division of Medi-Cal Fraud and Elder Abuse under state law, or county district attorney cases.

Do you handle Medical Board of California license defense?

No. Medical Board, Dental Board, Board of Pharmacy, and nursing board discipline are California state licensing proceedings requiring California license counsel. We defend the federal matter and coordinate with your license counsel — which matters, because statements and productions in one proceeding are usable in the other.

Are you licensed in California?

Our California lead, Carolyn L. Oliver, practices in California, and our federal practice is national. Federal criminal and False Claims Act practice is conducted in United States District Courts under federal law and federal admission rules, and we appear in federal courts nationwide, including all four California federal districts.

How do I find a lawyer experienced in health care fraud defense?

Ask four questions of any firm you interview: (1) How many federal health care fraud matters have you resolved before indictment? (2) Who on your team has actually worked inside a U.S. Attorney’s Office in a California federal district? (3) How do you handle the exclusion, revocation, and payment suspension track — in-house or referred out? (4) Who will actually work my file? The answers separate firms quickly.
