Medicare Fraud Strike Forces: The National Network and Its Changing Footprint

The Medicare Fraud Strike Force is a federal network that combines claims analysis, investigators and prosecutors to pursue health care fraud. Its teams connect billing patterns across providers and places. An insider can explain the decision behind the pattern: why a supplier changed its billing identity, why a medical record was rewritten, or why a warning reached management and the claims kept going. Those are different kinds of knowledge, and a strong case brings them together.

What Is the Medicare Fraud Strike Force?

The Strike Force brings prosecutors and investigators together to pursue healthcare fraud. Justice Department prosecutors work with U.S. Attorneys’ Offices, HHS Office of Inspector General investigators, the FBI and other agencies. The Centers for Medicare & Medicaid Services contributes program and payment expertise, while state and local partners bring their own investigative knowledge. State Medicaid Fraud Control Units also participate in joint investigations.

The network reaches beyond Medicare. The same coordinated action can include Medicare and Medicaid cases, private insurance and other federal health programs. The fraud takes money intended for patients’ care and leaves taxpayers paying for it. The June 2026 action included criminal charges over allegedly unnecessary amniotic wound grafts, alongside equipment and hospice schemes.

Current Medicare Fraud Strike-Force Locations

The Justice Department listed nine forces in its June 2026 national announcement and described their regional operations in separate agency pages. The table includes expansions announced through August 2026.

The Justice Department’s West Coast launch announcement tied that expansion to claims patterns moving into Arizona and Nevada and to Northern California’s health technology sector. Los Angeles remains a separate force. The National Rapid Response Strike Force supplies national coordination alongside the regional teams.

What State Has the Highest Medicare Fraud?

Strike Force locations and prosecution counts do not establish which state has the highest Medicare fraud. They show where enforcement operates. A provider’s office, the patients, the bank receiving payment and the court hearing a case can all be in different places.

The June 2026 action reached 56 federal districts. That reach reflects collaboration with U.S. Attorneys’ Offices beyond the regional teams’ usual footprint.

Medicare Strike Force Versus HCF Unit

A Medicare Strike Force is the interagency team. The Health Care Fraud Unit is the Justice Department component supplying specialist prosecutors and analysts to work with investigative agencies and local federal prosecutors.

The Justice Department’s August 2026 overview places the Health Care Fraud Section within its new National Fraud Enforcement Division.

Civil False Claims Act cases also involve the Civil Division and U.S. Attorneys’ Offices. The Centers for Medicare & Medicaid Services and its Medicare review contractors handle payment and enrollment work. The HHS Office of Inspector General has separate administrative powers, including civil monetary penalties and corporate integrity agreements.

How National Healthcare Fraud Coordination Works

National healthcare fraud coordination combines claims analysis with financial records, interviews and agency referrals. A pattern becomes useful when investigators can connect it to the service, the people controlling the business and the money.

In Original Medicare, an enrolled provider submits a claim, a contractor processes it, a remittance explains the payment decision, and a funds transfer records the money paid. Those records describe different steps. A billing employee may see what was submitted. A clinician may know what care occurred. Finance may know which account received the proceeds.

Part D adds another payment chain: pharmacy transactions, sponsor drug-event data, rebate reporting and federal reconciliation. The pharmacy counter and the sponsor’s federal submission can each hold part of the explanation. Following the business across those steps is why a national investigation needs more than a large billing total.

The Health Care Fraud Unit’s Data Fusion Center brings together Justice Department analysts, the HHS Office of Inspector General, the FBI and other agencies. In its June 2026 announcement, the department described using the center’s analysis in charged cases and combining claims analysis with financial analysis through a Financial Intelligence Review Team.

What the Data Can Show

A 2018 Journal of Big Data study, Big Data fraud detection using multiple medicare data sources, tested Part B, Part D and durable medical equipment data separately and together. Combining those sources let the researchers examine a provider across payment streams, though its overall results were not significantly better than Part B alone.

A 2023 study in the same journal, Explainable machine learning models for Medicare fraud detection, reduced its Part D dataset from 82 to 10 features. Models using those fewer inputs classified better than models using all of them. Fewer inputs also made it easier to understand what information a model uses.

An employee adds what happened inside the business: who supplied the order, changed the billing rule or approved the payment arrangement. We connect that knowledge to the orders, claims, warnings and payments behind the pattern.

What Happens to a Contractor’s Lead

A Unified Program Integrity Contractor can review records, interview beneficiaries and refer a suspected fraud scheme to the HHS Office of Inspector General. The Medicare program-integrity manual describes that route from a billing lead to an investigation.

The Centers for Medicare & Medicaid Services can suspend payments on a credible allegation of fraud while the investigation continues.

Is Stopped or Seized Money the Same as Money Returned to Medicare?

No. A stopped payment is money kept from leaving. Seized assets are money or property taken into government custody. Money returned to Medicare is a recovery reaching the program. Combining them makes an enforcement announcement look like a bank statement it never was.

The June 2026 national action announced charges against 455 defendants involving more than $6.5 billion in alleged false claims, alongside $23 million in civil settlements. Billions alleged. Millions settled. The charges concern alleged schemes; the civil settlements resolve allegations in separate cases.

The Centers for Medicare & Medicaid Services also suspended payments and revoked billing privileges as part of the action. Those measures can interrupt a business’s access to program money. A bigger headline should not make the money harder to follow.

How the Footprint Changed From Miami to a National Network

The Medicare Fraud Strike Force began in Miami-Dade in March 2007. Los Angeles followed in 2008. An interagency initiative in May 2009 brought the Justice Department and the Department of Health and Human Services together and added Detroit and Houston. Brooklyn, Tampa and Baton Rouge followed later that year, then Dallas and Chicago in 2011.

The later expansion included both geography and specialization. Newark/Philadelphia formed in August 2018. The Appalachian Regional Prescription Opioid force followed that October. New England’s Prescription Opioid force began in 2022 with Maine, New Hampshire and Vermont. Boston joined the New England footprint in 2025.

The Justice Department’s National Rapid Response Strike Force dates to September 2020. The FBI formed its separately named rapid-response team in fiscal 2021.

The 2026 additions included the Midwest expansion into Minnesota and the Northeast office expansion in Eastern Pennsylvania. Philadelphia had already participated through the earlier Newark/Philadelphia force.

The Decisions Behind the Billing Pattern

Claims patterns can reveal unusual volume, changing provider identities and services attributed to particular patients. Inside records explain how those patterns were produced. That is where someone who knows the business can make the investigation much more specific.

A Different Provider Number, the Same Control

In its criminal indictment for Operation Gold Rush, the government alleged that participants acquired enrolled durable medical equipment companies, installed nominee owners and billed for items never delivered. Accounts in company names and transfers through other entities formed part of the alleged scheme. The missing equipment behind the claims and the control of the billing business belonged in the same inquiry.

A parallel appears in the government’s complaint involving Regency, Inc. It alleged that scrutiny of one supplier could lead to claims moving to another supplier under the same control:

A new billing identity could leave the same people running the business. The employee who knows who controlled both companies can explain a connection that the company names conceal.

The Records Were Changed to Improve the Numbers

In its account of the June 2026 criminal charges, the Justice Department alleged that a California hospice owner bought information about recently deceased Medicare beneficiaries from a funeral home employee. The alleged purpose was to reduce the hospice’s apparent proportion of patients discharged alive. The owner allegedly billed for care those people had never received and created backdated medical records.

The alleged response to scrutiny was to add dead patients to improve the numbers. We call that manufacturing a better metric. Someone who knew how the names entered the system, or who created the records, could explain exactly what the improved statistic concealed.

A Warning Reached Management and the Rule Stayed

UCHealth agreed to pay $23 million to resolve civil allegations of emergency-department upcoding. The government alleged that an automatic emergency-department coding rule used vital-sign checks and elapsed time to generate higher-level facility claims. In its settlement agreement, the government also alleged that UCHealth ignored employee warnings and repeated high-outlier reports, and adjusted individual bills after patient complaints without fixing the underlying problem.

That is a parallel about knowledge inside the business. A coder can explain the rule. A manager can explain the warning. Someone handling patient complaints may know whether a correction reached only the person who complained. Those details connect what the business knew to the claims it continued submitting.

Do You Get a Reward for Reporting Fraud?

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. A billing, clinical, pharmacy or finance role can give an insider knowledge of a different part of the same scheme. Our whistleblower experts build your case around what you know and bring in Medicare fraud whistleblower lawyers who understand the scheme.

When You Know Why the Claims Changed

If you know why claims moved to another supplier, records appeared after the fact or management left a billing problem in place, speak with our whistleblower experts about what happened inside the business. We build the connection between your knowledge and the Medicare payments, bring in Medicare fraud whistleblower lawyers suited to the scheme, and stay beside you throughout the case.
