Medicare and Medicaid Fraud: Different Programs, Payments and Investigators

The difference between Medicare and Medicaid fraud starts with who pays: the federal government runs Medicare, while states administer Medicaid. The same provider, patient or billing practice can involve both. If you work in billing, clinical care or a health plan, the difference matters because the record you see may describe only one part of the money moving through the business.

Is Medicare Fraud the Same as Medicaid Fraud?

No. Medicare and Medicaid have separate payment systems, even when they cover the same patient or appear in the same fraud investigation. Medicare pays through Original Medicare, Medicare Advantage and prescription drug plans. Medicaid brings state administration and state-program payments into the picture.

The conduct can overlap. Billing for care never delivered, inflating the description of care, paying for referrals and keeping overpayments all appear in healthcare fraud cases. The useful question is which claim, report or payment carried the false account of the work.

A pharmacy’s inventory can expose a claim for drugs never dispensed. A therapist can recognize treatment minutes added to a chart. A plan employee may see a payment report that keeps a rebate out of Medicare’s calculation. Each sees a different connection between the work and the money. We follow that connection to the program that paid.

Who Pays and What the Claim Means

Original Medicare pays provider claims through contractors. Medicare Advantage and Part D use federal payments to private plans, with their own reporting. That difference determines where the financial consequence of a false record appears.

Original Medicare Pays the Provider’s Claim

Medicare Administrative Contractors process institutional, professional and supplier claims for the Centers for Medicare & Medicaid Services.

The Medicare remittance advice records how the claim was processed, including payment adjustments. The bank transfer shows the money that reached the provider. Account-level offsets can change that deposit. For someone in billing or finance, the submitted charge, the allowed amount and the deposit answer different questions about the same service.

Medicare Advantage Pays the Plan

Medicare Advantage organizations receive advance monthly payments to deliver Medicare benefits. The plan’s payment to a provider is another transaction. Diagnosis information used for risk adjustment can affect the federal payment to the plan.

That was the payment question in the Kaiser Permanente settlement announced in January 2026. The government alleged that unsupported diagnoses increased Medicare Advantage payments. The allegation concerned what Medicare paid the plan through risk adjustment.

Part D Follows the Drug Into the Sponsor’s Reports

Part D covers outpatient prescription drugs through approved sponsors. A pharmacy claim goes through a plan or pharmacy benefit manager. The sponsor then reports prescription drug events and drug-cost concessions to CMS, which reconciles relevant federal payments. Medicare Advantage plans with prescription coverage retain this distinct Part D payment path.

In the Elixir Insurance Company and Rite Aid settlement, the government alleged that retained manufacturer rebates were reported as service fees that did not qualify for that treatment. The alleged distortion sat in the sponsor’s reporting of drug costs. Following only the prescription would miss it.

Medicaid Brings the State Program Into View

Medicaid payments require attention to the state program and any managed-care payer involved. A patient who also has Medicare may receive full Medicaid benefits or only help with Medicare premiums and cost sharing. Those arrangements create different payment records.

Dual Eligible Special Needs Plans show how closely the programs can meet. The American Institutes for Research’s 2026 report, Medicare Advantage Fraud, Waste, and Abuse Policy Options, describes these as Medicare Advantage plans for people eligible for both programs, with care-coordination requirements and contracts with state Medicaid agencies. It identifies a risk in look-alike plans that enroll dual beneficiaries while avoiding the same coordination requirements or misleading people about integrated coverage.

For a plan insider, the state contract and the promised coordination can be central to the concern. Having the same patient in both programs makes the connection worth examining.

Medicare Versus Medicaid Fraud Investigators

Federal and state investigators can work together on the same scheme. CMS and its contractors handle payment integrity, the Department of Health and Human Services’ Office of Inspector General and the FBI investigate, and the Justice Department handles federal civil cases and criminal prosecutions. State Medicaid Fraud Control Units participate in investigations and state recovery efforts.

Unified Program Integrity Contractors investigate leads through claims analysis and medical review, and make referrals to law enforcement. CMS describes their role in its program-integrity report to Congress.

A state unit can also help investigate a Medicare scheme. The Justice Department’s announcement of a laboratory owner’s jury conviction credits the Texas Medicaid Fraud Control Unit among the investigators. The case concerned Medicare laboratory billing.

What Is the Medicare Fraud Strike Force?

The Medicare fraud strike-force network coordinates federal health care fraud investigations and prosecutions involving public and private payers. A national action can bring together Medicare, Medicaid and private-insurer cases. The shared announcement brings the cases together for enforcement, while each case still has its own claims and payers.

When One Scheme Touches Both Programs

For someone covered by both Medicare and full Medicaid, Medicare generally pays first for Medicare-covered services, subject to other primary coverage. Medicaid may cover additional benefits and acts as payer of last resort. A crossover transfers an already processed Medicare claim to another payer. The receiving payer’s payment record establishes what happened to the money.

The Medicare crossover guidance describes that transfer of information. A billing employee may see the crossover indicator before seeing the other payer’s response. We connect the two when examining whether the same false service description produced payments from both programs.

The Congressional Research Service explained the value of looking across programs in its 2011 report on Medicare program integrity:

For an insider, a pattern can become visible when the separate payment files meet.

When Reimbursement Drives the Discharge Decision

The whistleblower’s complaint against Strauss Ventures alleged that financial targets displaced the treating therapists’ judgment about discharge:

We see the absurdity in that allegation: the reimbursement target gets the final say over the treating therapist. Patients kept in therapy, taxpayers paying for it. The therapist’s judgment, the facility’s instructions and the claims to each program would answer different parts of the same question. The payment trail shows which program funded which care.

Medicare and Medicaid Mixed-Payer Settlement

A Medicare and Medicaid mixed-payer settlement can resolve claims to both programs in one civil agreement. Medicaid claims can also bring federal and state recoveries together, as the hospital settlement below shows.

Tenet Healthcare’s civil settlement announced in October 2016 resolved allegations that referral kickbacks caused claims to federal and state health programs. The civil amount was $368 million, with separate allocations to the United States, Georgia and South Carolina.

The Continuum Health Partners settlement makes the federal-share point especially clear. The hospital group admitted delayed repayment of erroneous New York Medicaid claims and agreed to a combined federal and state settlement of $2.95 million in August 2016. The federal settlement document allocated $1.18 million to the United States. This was Medicaid money with a federal recovery interest.

Private Supplemental Payments Have Their Own Trail

Operation Gold Rush shows how far apart the payers’ numbers can be. According to the Justice Department’s June 2025 account of the criminal indictment, organizers allegedly bought durable medical equipment companies already able to bill Medicare and supplemental insurers, used nominee owners and submitted false claims using stolen identities.

The department reported approximately $41 million in Medicare payments and nearly $900 million in payments from Medicare supplemental insurers in the alleged scheme. HHS-OIG and CMS prevented most of the money sought from Medicare from being paid. The bigger payday came from the supplemental insurers.

What a Whistleblower Can See

An insider can connect a clinical or billing decision to the claim and the payment it produced. The person entering the claim, the person directing the work and the person controlling the proceeds may have different roles. Knowing how those roles connect is often the value of being inside the business.

Our work on Medicare fraud evidence connects orders, care records, claims, warnings and payments. In a case spanning programs, we also follow which payer received the representation and which business received the money. Your firsthand account can explain why the records changed or why a known payment problem continued.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
