Massachusetts Federal Healthcare Fraud Defense Attorney

The Investigation Stage — What Happens Before You Are Charged

Federal healthcare fraud investigations in Massachusetts rarely begin with an arrest. They begin quietly — with a data anomaly flagged by CMS’s statistical algorithms, a disgruntled former employee, a competitor’s complaint, or a qui tam relator who has already filed a sealed False Claims Act lawsuit. By the time the government’s investigation becomes visible to you, it may have been underway for a year or more.

The earliest signals typically appear in one of several forms. A grand jury subpoena for records — billing data, compliance communications, contracts, or patient files — is the most common entry point. Federal agents may conduct “knock and talk” interviews with employees, former staff, or colleagues without prior notice. A search warrant executed at your office or home represents a significant escalation, typically signaling that prosecutors believe evidence may be destroyed if formal notice is given. A target letter from the USAO for the District of Massachusetts is the most direct signal: it means the government has substantial evidence linking you to a federal offense and is actively considering seeking an indictment.

None of these events require you to speak to investigators without counsel present. The instinct to explain, cooperate, or demonstrate good faith by answering questions without an attorney is one of the most dangerous mistakes a healthcare professional can make in a federal investigation. Statements made to federal agents can be used against you regardless of whether they are recorded — and an agent’s characterization of what you said carries significant weight with prosecutors and grand juries.

The pre-indictment phase is also the window of greatest strategic opportunity. Pre-indictment defense work — presenting evidence to prosecutors, engaging in resolution discussions, challenging the legal theory before charges are filed, or demonstrating that the alleged conduct falls within a regulatory safe harbor — can in some cases prevent charges entirely. That window closes at indictment. Retaining counsel at the first sign of federal healthcare fraud scrutiny is not premature — it is the decision that determines what options remain.

Federal Healthcare Fraud Charges — What the Government Must Prove

Federal healthcare fraud prosecutions in Massachusetts are built on a set of overlapping statutes, each with distinct elements that the government must establish beyond a reasonable doubt.

Federal Healthcare Fraud (18 U.S.C. § 1347) requires the government to prove that the defendant knowingly and willfully executed — or attempted to execute — a scheme to defraud a healthcare benefit program, or to obtain money from a healthcare benefit program by false pretenses, representations, or promises. The “knowingly and willfully” element is frequently the central battleground. The government must demonstrate that the defendant was aware that the conduct was unlawful — not merely that billing errors occurred or that a compliance program was inadequate.

The False Claims Act (31 U.S.C. §§ 3729–3733) creates civil liability — and in criminal referral cases, potential criminal exposure — for knowingly presenting or causing to be presented a false claim for payment to the federal government. FCA cases in Massachusetts frequently begin as qui tam lawsuits filed under seal by a whistleblower — a former employee, a competitor, or a patient advocate — who receives a percentage of any recovery. The government then investigates and decides whether to intervene. FCA liability includes treble damages plus per-claim civil penalties, and the government’s ability to identify thousands of individual billing submissions as separate “claims” can produce exposure that dwarfs any individual billing error.

The Anti-Kickback Statute (42 U.S.C. § 1320a-7b) prohibits offering, paying, soliciting, or receiving anything of value to induce referrals of federally reimbursable services. AKS violations are a predicate offense for FCA liability, meaning that claims submitted in connection with an illegal kickback arrangement are automatically false claims under the FCA regardless of whether the services were actually rendered. Safe harbors exist — for employment arrangements, personal services contracts, and certain investment interests — but their application is highly fact-specific and requires detailed analysis of actual business arrangements.

The Stark Law (42 U.S.C. § 1395nn) prohibits physician self-referral for designated health services billed to Medicare or Medicaid unless a specific statutory exception applies. Unlike the AKS, the Stark Law is a strict liability civil statute — intent is not an element. A Stark violation does not require a corrupt intent or even knowledge that the arrangement was problematic. What it requires is a referral relationship and a financial relationship between the referring physician and the service entity, combined with the absence of an applicable exception.

Wire fraud (18 U.S.C. § 1343) is regularly added to healthcare fraud indictments as an independent count. Each electronic submission of a fraudulent claim — each instance of electronic billing — constitutes a separate wire fraud act, allowing prosecutors to multiply the count total and, correspondingly, the sentencing exposure. Wire fraud carries up to twenty years per count.

Bail, Detention, and the Immediate Consequences of Arrest

Most federal healthcare fraud defendants in Massachusetts are not arrested at dawn. They are typically permitted to self-surrender following an indictment, or they are notified by counsel that charges are forthcoming and arrangements are made for an orderly initial appearance before a magistrate judge. This reflects the white-collar profile of most healthcare fraud defendants — professionals with deep community ties, no prior criminal history, and significant financial resources — who present a lower flight risk than defendants in drug trafficking or organized crime cases.

That said, cases involving search warrant execution can move rapidly toward arrest, and the government will occasionally seek detention in healthcare fraud matters where it believes the defendant poses a continuing risk of obstruction — destroying records, intimidating witnesses, or transferring assets ahead of a forfeiture proceeding.

At the initial appearance and detention hearing, the defense has an opportunity to present evidence of ties to the community, professional and family obligations, the absence of a prior criminal history, and the availability of conditions — electronic monitoring, passport surrender, restricted travel — that would reasonably assure the defendant’s appearance at trial. The outcome of that hearing sets the tone for everything that follows: a detained defendant faces profound disadvantages in case preparation, employment continuity, and family stability.

Even for defendants released pending trial, pretrial conditions in healthcare fraud cases often include restrictions on professional activity. The court may prohibit continued billing to federal healthcare programs, impose no-contact conditions with alleged co-conspirators, or require regular check-ins with pretrial services. Understanding the scope and limits of those conditions — and challenging overbroad restrictions that interfere with legitimate professional activities — requires defense counsel who is present and engaged from the initial appearance forward.

The Evidence That Decides Federal Healthcare Fraud Cases

Federal healthcare fraud prosecutions in Massachusetts are built on documentary and electronic evidence. Understanding what the government has — and what it cannot prove — is the foundation of any effective defense strategy.

Billing records and claims data are the evidentiary core of most healthcare fraud prosecutions. CMS maintains claims data on every Medicare and Medicaid submission, and prosecutors routinely analyze years of billing records to identify statistical outliers, patterns of upcoding, or services billed for dates when the patient was documented as hospitalized or deceased. Defense analysis of the same data — challenging the government’s methodology, identifying legitimate explanations for billing patterns, or demonstrating that the rate of anomalous claims is consistent with industry norms — is a critical component of pre-trial preparation.

Medical records in upcoding and medically unnecessary services cases become the battleground for whether the clinical documentation actually supports the billed service level. Government experts will review records for compliance with documentation requirements; defense experts must do the same analysis and identify where the government’s methodology is flawed, where legitimate clinical complexity justified the billed code, or where documentation gaps reflect record-keeping failures rather than fraudulent intent.

Electronic communications — email, text messages, internal messaging platforms, and voicemails — are frequently the most damaging evidence in healthcare fraud cases. Prosecutors look for communications that establish knowledge of improper billing, awareness of regulatory requirements that were knowingly violated, or explicit discussions of kickback arrangements. They also look for communications that could be construed as consciousness of guilt — directions to alter records, discussions of what to say to auditors, or statements comparing the alleged scheme to practices at competitor organizations.

Cooperating witnesses and co-defendants present a distinctive evidentiary challenge. Federal healthcare fraud investigations are frequently multi-defendant matters — involving billing companies, referring physicians, facility operators, and executives at multiple levels of an organization. The government’s ability to offer plea agreements and cooperation credit to lower-level participants creates witnesses who may testify about what they were told, instructed, or led to believe by more senior defendants. The credibility of cooperating witnesses — their motivations for cooperation, their prior inconsistent statements, the benefits they received in exchange for testimony — is often the most productive area of cross-examination.

Expert witnesses are nearly always required in healthcare fraud cases. The government will present coding experts, physicians, and billing specialists who will testify that the billed services were not medically necessary, that documentation did not support the claimed service level, or that the compensation arrangements at issue violated the Anti-Kickback Statute. The defense must be prepared to retain and prepare its own qualified experts — clinicians who can explain legitimate clinical decision-making, healthcare compliance specialists who can establish that the alleged arrangements fell within recognized safe harbors, and economists or statisticians who can challenge the government’s damages calculations.

Defense Strategy — What Effective Healthcare Fraud Defense Actually Looks Like

Healthcare fraud defense is not general criminal defense applied to a healthcare context. It requires the integration of federal criminal procedure with a deep, specific understanding of the healthcare regulatory environment, Medicare and Medicaid billing rules, and the enforcement priorities and litigation tendencies of the USAO for the District of Massachusetts.

Early case assessment begins with a systematic review of every document the government has obtained or is likely to obtain. This means conducting an internal investigation before the government’s investigation matures — identifying the strongest evidence against the client, understanding how the government will characterize the relevant business arrangements, and assessing whether the alleged conduct is accurately characterized as fraud or whether it reflects regulatory ambiguity, billing complexity, or compliance failures that do not rise to criminal intent. The difference between a criminal referral and a civil settlement often turns on decisions made in the pre-indictment phase.

Regulatory safe harbor and exception analysis is frequently the most consequential legal work in a healthcare fraud defense. The Anti-Kickback Statute contains numerous regulatory safe harbors — for employment relationships, personal services contracts, referral arrangements with fair market value compensation, and specific industry practices — that can shield arrangements from criminal liability even if they involve remuneration connected to referrals. Stark Law exception analysis requires a detailed comparison of the actual financial arrangement against the specific technical requirements of each potentially applicable exception. Identifying a viable safe harbor or exception can be the difference between criminal prosecution and a civil audit.

Pre-indictment engagement with prosecutors is a strategic decision that requires careful judgment. In some cases — particularly where the legal theory is contestable, where the alleged fraud involves regulatory ambiguity rather than deliberate misrepresentation, or where the defendant’s individual culpability within a larger organizational structure is genuinely limited — presenting evidence to the AUSA handling the matter before the grand jury returns an indictment can lead to a declination, a civil-only resolution, or a significantly narrowed charge. This is not a strategy for every case, and its execution requires counsel who understands how the USAO’s healthcare fraud unit evaluates cases and what evidence is most likely to be persuasive.

Motion practice in healthcare fraud cases typically centers on the scope of grand jury subpoenas, the propriety of search warrant affidavits and the particularity of items seized, the admissibility of expert testimony under Daubert standards, and the sufficiency of the government’s loss calculation methodology. Suppression motions that succeed in healthcare fraud cases frequently turn on deficiencies in the warrant affidavit’s probable cause showing or on the government’s failure to limit the scope of a search to items within the warrant’s authorization.

Parallel civil and criminal track management is essential in any FCA-involved matter. The government may pursue civil FCA liability simultaneously with criminal prosecution, and a qui tam relator’s counsel is actively litigating the civil case even while the criminal matter proceeds. Statements, admissions, and strategic decisions made in one proceeding can have consequences in the other. Defense counsel must coordinate the response to both tracks from the earliest stages of representation.

Trial preparation and sentencing advocacy in healthcare fraud cases require the same level of preparation as any serious federal felony. The government’s trial presentations in this district are thorough, document-intensive, and often involve expert testimony that must be effectively cross-examined and countered by defense experts. If a plea becomes appropriate, the sentencing guidelines calculation in healthcare fraud cases — driven primarily by the government’s loss amount calculation — is frequently the most vigorously contested issue at sentencing, and a well-prepared sentencing memorandum addressing role in the offense, cooperation credit, and individual mitigation factors can produce outcomes well below the advisory guideline range.

Types of Healthcare Fraud Cases We Handle in Massachusetts

Marin & Murphy represents individuals and organizations across the full spectrum of federal healthcare fraud enforcement in the District of Massachusetts.

Medicare and Medicaid billing fraud cases — involving upcoding, unbundling, phantom billing, and billing for medically unnecessary services — represent the most common healthcare fraud prosecution category. These cases are built on claims data analysis and medical record review, and they require defense counsel capable of engaging with both the documentary record and the clinical standards that govern proper billing.

False Claims Act civil and criminal defense requires understanding of the qui tam mechanism, the government’s intervention decision process, and the coordination between DOJ Civil Division and the USAO’s criminal prosecutors. When the government intervenes in a qui tam case and refers the matter for criminal prosecution, defendants face simultaneous exposure from two separate government offices pursuing the same underlying conduct through different legal tracks.

Anti-Kickback Statute defense in Massachusetts involves pharmaceutical companies, device manufacturers, hospital systems, and independent physician groups. Enforcement has expanded significantly in recent years to include arrangements that were previously understood to be standard industry practice — speaker program payments, consulting arrangements, and formulary management relationships that prosecutors now characterize as kickback schemes.

Telemedicine fraud prosecutions have proliferated nationally and in Massachusetts, following the pandemic-era expansion of remote prescribing and the government’s subsequent enforcement focus on sham telehealth consultations, DME kickback schemes, and unnecessary prescription arrangements driven by financial incentives rather than clinical need.

Home health and hospice fraud is a priority enforcement area for the Massachusetts Attorney General’s Medicaid Fraud Division and HHS-OIG, with multiple indictments in Worcester County in recent years targeting GAFC providers, medical transportation companies, and home health agencies for billing MassHealth for services not rendered or not properly documented. These cases frequently involve both state and federal charges, with the USAO taking jurisdiction when the fraud magnitude or interstate connections bring the matter within federal enforcement priorities.

Research grant fraud and NIH/NSF misrepresentation is an emerging prosecution category in Massachusetts, accelerated by the Dana-Farber Cancer Institute’s $15 million False Claims Act settlement in December 2025 for misrepresented research data in NIH-funded publications. Principal investigators, research directors, and university compliance officers whose grant submissions or progress reports contain inaccurate representations about research data, personnel qualifications, or use of funds face both FCA civil liability and potential criminal exposure under 18 U.S.C. § 1001 for false statements to a federal agency.

Pharmaceutical and clinical trial fraud prosecutions in Massachusetts target off-label promotion schemes, adulteration of drug products, manipulation of clinical trial data, and misrepresentation of study results to FDA. Boston’s concentration of pharmaceutical manufacturers and clinical research organizations makes this a recurring enforcement area, with cases frequently involving parallel FDA enforcement and DOJ criminal prosecution.

Private equity healthcare fraud is an emerging enforcement priority identified by the USAO at the Boston Bar Association White Collar Crime Conference. As private equity firms have consolidated healthcare assets across Massachusetts, prosecutors have focused on financial arrangements that obscure ownership relationships, management fee structures that the government characterizes as kickbacks, and cost-cutting decisions that produce systematic billing fraud at portfolio companies.

Penalties, Collateral Consequences, and What Is Actually at Stake

Federal healthcare fraud penalties in Massachusetts extend far beyond the formal sentence imposed by a district court judge. For healthcare professionals, the collateral consequences of a conviction — or even of a deferred prosecution agreement — are often more severe and more permanent than the criminal sentence itself.

Criminal sentences under the U.S. Sentencing Guidelines for healthcare fraud are primarily driven by the loss amount calculation — the total value of claims the government attributes to the fraudulent scheme. The loss calculation methodology is frequently aggressive, and the resulting guideline ranges for large-scale healthcare fraud cases regularly fall in the range of five to fifteen years even for first-time offenders. Wire fraud counts, money laundering enhancements, and role-in-the-offense adjustments can push guideline calculations significantly higher.

Medicare and Medicaid exclusion is mandatory upon conviction of a healthcare-related offense under 42 U.S.C. § 1320a-7. Exclusion means that no federal healthcare program — Medicare, Medicaid, CHIP, TRICARE, or VA — will pay for any item or service furnished, ordered, or prescribed by the excluded individual. For any healthcare professional whose practice depends on federal program reimbursement, mandatory exclusion is effectively a prohibition on practicing medicine in any commercially viable setting. Exclusion periods for program-related convictions are a minimum of five years; for aggravated cases, they are permanent absent successful reinstatement proceedings before the OIG.

Professional license revocation proceedings at the Massachusetts Board of Registration in Medicine, the Board of Pharmacy, the Division of Professional Licensure, and comparable licensing bodies begin automatically following a federal healthcare fraud indictment — not just a conviction. The Board of Registration in Medicine may suspend a license on an emergency basis pending the criminal proceeding, depriving a physician of the ability to practice before the case is resolved. Defense in licensing proceedings must be coordinated with criminal defense strategy from the earliest stages.

Asset forfeiture in federal healthcare fraud cases can target proceeds of the alleged fraud and property connected to the scheme. Forfeiture proceedings may be initiated before trial, and the government may seek to freeze assets that would otherwise be available to fund a legal defense. Understanding the scope of forfeiture exposure and structuring asset management in a way that preserves resources for defense without creating additional legal risk is a critical component of early representation.

Treble damages and civil penalties under the False Claims Act can produce civil liability that dwarfs the criminal fine. In cases involving thousands of individual false claims, the per-claim civil penalties — currently ranging from approximately $13,000 to $27,000 per claim — alone can produce liability in the tens of millions of dollars before any trebling of actual damages.

Why Experience in Federal Healthcare Fraud Defense Matters

The gap between a general criminal defense practice and a healthcare fraud defense practice is significant. Healthcare fraud cases require fluency in Medicare and Medicaid reimbursement rules, clinical documentation standards, the specific regulatory safe harbors under the Anti-Kickback Statute, and the mechanics of the qui tam False Claims Act process — areas of law that have no parallel in state criminal practice and that most general criminal defense attorneys encounter only occasionally.

Attorney Stefanie A. Murphy has handled serious felony cases at trial and on appeal in matters where the stakes — career, freedom, professional reputation — were irreversible. The Providence Journal has covered Murphy’s work across murder acquittals, wrongful conviction DNA litigation, and high-profile jury trials in Rhode Island. Murphy’s authorship of the MCLE New England treatise A Practical Guide to Trying DUI Cases in Rhode Island (2nd Edition 2024) and her work lecturing to the Rhode Island Municipal Police Training Academy reflect the depth of legal preparation she brings to every matter. Rhode Island Lawyers Weekly has independently identified both Murphy and Matthew T. Marin as attorneys who have shaped constitutional litigation across search-and-seizure and evidentiary law — not simply practiced it.

Attorney Stefanie A. Murphy is admitted to the U.S. District Court for the District of Massachusetts (D. Mass. Federal Bar #663646). Matthew T. Marin is admitted in Massachusetts state courts (BBO #672462). The firm represents clients in federal matters across three states. Its Massachusetts practice operates within the First Circuit, where the Court of Appeals also reviews Rhode Island cases; its Connecticut practice operates within the Second Circuit. That footprint produces cross-jurisdictional experience directly applicable to federal healthcare fraud matters. The firm’s involvement in complex, document-intensive civil litigation reflects a capacity for multi-party matters that directly informs its approach to healthcare fraud cases involving extensive billing records, multiple co-defendants, and parallel civil and criminal proceedings.

Healthcare fraud defendants in Massachusetts are typically physicians, executives, administrators, and researchers — people with no prior criminal history, significant community ties, and professional stakes that make the collateral consequences of a conviction as serious as the criminal sentence. They deserve counsel who understands both the law and the specific professional, regulatory, and reputational context in which the case arises. That understanding informs every aspect of the defense — from the first conversation with a prosecutor to the final sentencing argument before a district judge.

Where trial counsel’s errors shaped the verdict, vacating a federal conviction under § 2255 may still be possible.
