Medicare Fraud: The Payment Follows the Paperwork

Medicare fraud uses knowingly false claims, records or payment reports to obtain Medicare money, or knowingly keeps money that should be returned. A claim can describe a visit that never happened, an order the doctor never signed or a prescription the patient never received. Someone inside the business may know exactly where that story changed: the coding instruction, the delivery record, the audit warning management left unanswered. That knowledge can connect an apparently ordinary payment to the decision that made it fraudulent.

What Counts as Medicare Fraud Across Parts A, B and D?

Medicare fraud across Parts A, B and D includes billing for undelivered care, falsely describing services, buying referrals and misreporting information that determines federal payment. The payment system determines where the falsehood does its work. A hospital claim, an equipment supplier’s delivery claim and a drug plan’s annual rebate report tell Medicare different things.

How Medicare pays follows four parts: Part A covers hospital insurance benefits, Part B covers professional and outpatient services, Part C provides the Medicare Advantage route, and Part D covers outpatient prescription drugs through approved sponsors. Medicare serves older people and people qualifying through disability or end-stage renal disease.

Medicare Fraud by Payment System

In Original Medicare, a provider’s enrollment establishes its billing authority. The provider documents a service and submits a claim. A Medicare Administrative Contractor processes it, applies payment rules and issues a remittance explaining the result. The bank transfer follows, sometimes reduced by adjustments against other amounts the provider owes.

That is why a billing department’s claim total and the deposit in the bank can tell different stories. The submitted charge, allowed amount and Medicare payment each describe a different stage. The Medicare Claims Processing Manual sets out the contractor’s processing framework. The underlying clinical and delivery records explain what actually happened.

Part A includes inpatient hospital care, skilled nursing, hospice and some home health benefits. Part B reaches physician services, outpatient care, laboratory tests, durable medical equipment, qualifying ambulance transport and certain drugs. Hospital payment can depend on the classification of a discharge, while professional payment depends on the service, resources and setting. Changing those descriptions changes what Medicare pays.

Part D adds another transaction. The pharmacy submits a prescription claim through a plan or pharmacy benefit manager. The sponsor sends prescription drug event data to the Centers for Medicare and Medicaid Services and reports rebates and other price concessions. The agency later reconciles federal payments against the relevant costs and subsidies. The pharmacy transaction and the sponsor’s final federal payment sit at different ends of that process. Outsourcing work to a pharmacy benefit manager leaves the sponsor responsible for its CMS contract.

Part C pays Medicare Advantage organizations in advance each month, with risk adjustment affecting the amount. The plan’s payment to a provider is another transaction. A Medicare Advantage plan that also offers prescription coverage still has a distinct Part D reporting and payment obligation.

Is Medicare Fraud the Same as Medicaid Fraud?

Medicare and Medicaid fraud involve different programs and payment responsibilities. Medicare is federal. Medicaid has state-program claims and enforcement interests. A patient can have both. Medicare ordinarily pays first for Medicare-covered services, with Medicaid potentially helping with costs or additional benefits. An allegation needs to follow the claim to the program that paid it.

Why the Payment Rewards the False Story

Medicare pays for defined services and benefits using information supplied by the businesses seeking payment. A more expensive service code, a higher-paying hospital classification or a lower reported drug rebate can move money without changing the care the patient received. Fabricated care takes that incentive further: the claim produces revenue without the promised service.

This is why we look beyond the largest number in a headline. The money requested, the money paid and the money stopped tell different stories about the same scheme.

Operation Gold Rush involved approximately $10.6 billion in allegedly false Medicare claims, according to the June 2025 criminal indictment. It charged that equipment suppliers billed for medically unnecessary items they never delivered. The indictment put Medicare’s payments at approximately $41 million and estimated supplemental insurers’ payments at approximately $900 million.

The Justice Department’s 2025 review describes how its data analysts and partners detected unusual billing. The Department of Health and Human Services Office of Inspector General and the Centers for Medicare and Medicaid Services prevented nearly all the Medicare payments scheduled for the operation. The supplemental insurers kept paying. Different payment systems, very different results.

National Medicare fraud takedowns bring together cases across programs and insurers. Following the payment through each system shows who actually paid and where the scheme was stopped.

What Are the Most Common Causes of Improper Medicare Payments?

Insufficient documentation was the largest category in the $28.83 billion fee-for-service improper-payment estimate for fiscal 2025. Other categories in the CMS payment review included missing documentation, medical-necessity findings and coding errors. For an insider reading Medicare fraud statistics, the question behind the payment is what the business told Medicare and what it knew.

How the Claim Connects to the Decision

Useful Medicare fraud evidence connects the order, the care or delivery, the claim and the payment. An authentic prescription establishes what was ordered. A dispensing record describes what the pharmacy says it supplied. A claim records what the payer was told. A reversal and the payment records show whether the money came back.

Those connections reach across departments. A clinician may know the order was changed. A coder may know management imposed the billing rule. An accounts employee may know who controlled the bank account, while an auditor may know when the discrepancy was first raised. The person who transmitted the claim may be several steps away from the person who designed the practice.

The sequence after a warning can be especially revealing. Which claims were affected? What did the business change? Did the same billing continue? The original record, its later versions, the internal response and subsequent claims can put the decision in view. For a drug plan, that sequence may run through event-data corrections, rebate reports, payment certifications and reconciliation.

How Medicare Fraud Is Detected

Medicare fraud detection combines billing analysis with evidence about the care, the orders and the people controlling the payments. A National Bureau of Economic Research working paper published in 2026, Medicare Home Health Fraud: How Much, Where, and Who?, matched Medicare claims with federal strike-force prosecution records and modeled which agencies elsewhere would have been prosecuted.

The paper defined fraudulent agencies by prosecution and identified a pattern an insider could recognize:

Medicare Home Health Fraud: How Much, Where, and Who?, National Bureau of Economic Research, 2026

The finding directs attention to the referring physician, the care pattern and the patient’s condition. An insider can explain how those patterns came about, including the instructions and records behind them.

Who Sees Medicare Fraud and Who Investigates It

Whistleblowers can be coders, clinicians, pharmacy employees, auditors or people implementing the systems that produce claims. Their value lies in knowing how the business worked. A software implementer can understand the defect tickets. A coding trainer can connect instructions to chart changes. A pharmacy worker can explain the difference between a processed prescription and one a patient received.

Who Investigates Medicare Fraud?

The Centers for Medicare and Medicaid Services and its contractors review claims and payment. The HHS Office of Inspector General and the FBI investigate, and the Justice Department pursues civil cases and criminal prosecutions. The agencies investigating Medicare fraud have different jobs, even when they work on the same conduct.

Medicare audits and contractor reviews can examine claims before payment, revisit paid claims or investigate suspected problems. A contractor’s review findings and management’s response can show what the business knew and what it changed.

The Centers for Medicare and Medicaid Services can suspend payments during an investigation. The HHS Office of Inspector General also conducts audits and oversees integrity agreements. The Justice Department’s civil teams handle False Claims Act cases. State Medicaid Fraud Control Units can participate in joint investigations involving their interests and evidence. These roles explain why an insider’s account may matter to more than one agency.

What Is the Medicare Fraud Strike Force?

The Medicare fraud strike force model combines federal prosecutors, investigators and data analysts to pursue health care fraud. The Justice Department’s description brings together the FBI, the HHS Office of Inspector General, the Centers for Medicare and Medicaid Services and other agencies. The teams’ work reaches Medicare, Medicaid and other healthcare payers.

Does the False Claims Act Apply to Medicare?

Yes. The False Claims Act reaches knowingly false Medicare claims and payment records, including causing someone else to submit them and knowingly avoiding money owed back. A business can also be responsible when it deliberately looks the other way. What the business knew when it billed is part of the case, alongside the payment and the underlying records.

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. Medicare fraud whistleblower rewards come from the recovery through that case. The law allows a private person to bring a qui tam case on the government’s behalf. Our work starts with understanding the conduct and bringing in Medicare fraud whistleblower lawyers whose experience fits it.

How Do I Report Medicare Fraud?

Speak with our whistleblower experts about the false bill, order or payment report and what you know about the decisions behind it. If you know why the claim differs from the care, we can work with you on the decisions and records that connect that difference to the money. Questions about anonymity or your role inside the business belong in that conversation with us and the whistleblower lawyers we bring in.

The Medicare Fraud Schemes Behind the Payments

The common mechanism is a false account of something Medicare pays for. The details differ across hospitals, physician practices, nursing facilities, home health agencies, hospices, laboratories, equipment suppliers, ambulance services and pharmacies. The government’s national actions also connect telehealth businesses to equipment and genetic-testing claims. These are places to connect the payment to the actual service and the people directing it.

Medicare Phantom Billing and Undelivered Prescriptions

Medicare phantom billing was among the allegations behind Walgreens’ $106.8 million settlement announcement in 2024, covering government claims for prescriptions never dispensed. In the Part D agreement, the government alleged that Walgreens processed prescriptions patients never picked up or received and retained payments for them.

The pharmacy’s dispensing records, patient pickup or delivery information and payment reversals connect the prescription to the money. The same inquiry applies to equipment never delivered or a visit never made: what did the claim say happened, and what happened to the payment?

Stolen Medicare Numbers and Forged Orders

Stolen Medicare numbers and forged orders can feed claims on an enormous scale: the Gold Rush criminal indictment alleged misuse of more than one million Americans’ identities. It described beneficiaries receiving statements for equipment they never received, from unfamiliar suppliers, supposedly prescribed by doctors they had never visited.

In a separate criminal indictment in 2026, the government charged a medical office manager with forging signatures on laboratory requisitions and supplying patient identifiers even when no specimen had been given. The allegation followed the false order into the laboratory’s expected Medicare claim. Ordering records and specimen records give different people a view of that same transaction.

Medicare Enrollment Fraud and Hidden Control

Medicare enrollment fraud was part of the Gold Rush indictment’s account of approximately 19 equipment companies. Prosecutors alleged that the operation acquired enrolled suppliers, installed owners on paper and kept actual control elsewhere. Storefront employees collected reimbursement checks and followed instructions about deposits and transfers.

Enrollment forms identify the claimed owner. Bank access, payment instructions and communications can identify who actually ran the business. For an employee handling those instructions, the company name on the claim may explain very little about who controlled the money.

Upcoding, False Records and Unnecessary Care

UCHealth agreed to a $23 million settlement in 2024 over alleged emergency-department upcoding involving Medicare and TRICARE. The government alleged that an automatic rule tied billing to vital-sign checks and elapsed hours, while employee warnings went unanswered. The whistleblower’s complaint described how routine care could acquire a much more expensive label:

United States ex rel. Sanders v. University of Colorado Health, whistleblower’s complaint, paragraph 123

Routine vital-sign checks. Top-level billing. We see the alleged rule rewarding the label instead of the care. The settlement announcement concerned that payment practice. The patient, the nurse and the billing system could each describe the same visit differently.

Other schemes inflate service units, bill unnecessary care, submit duplicate claims or unbundle services already included in a broader payment. The useful comparison is between the actual care, the applicable payment method and what the claim represented.

Hospice Certifications and Ineligible Admissions

In a complaint against AseraCare, whistleblowers alleged that managers used terminal-illness certifications signed in blank to bill Medicare for ineligible patients. They also alleged that staff backdated recertification records to make them appear timely. The signatures and dates made the paperwork tell a different story from the care decision behind it.

Kickbacks and Paid Referrals

Kickbacks can buy the referral or order that makes the claim possible. The financial arrangement and the resulting test, treatment or equipment claim may sit in different businesses. The Anti-Kickback Statute targets payments made to buy federal health program business. Physician self-referral rules can bar Medicare payment when doctors send patients to businesses in which they have a financial interest.

The Justice Department’s annual review describes a criminal case in which laboratories obtained genetic-test orders through telemarketing. It reports that telemedicine physicians approved tests without meeting patients or conducting legitimate consultations, and the operator disguised kickbacks through sham contracts to secure the orders.

The evidence needs to connect the financial arrangement to the referral and the claim. That is why a marketer’s instructions, a physician’s orders and the provider’s billing can matter together.

Part D Rebate Reports That Change the Federal Bill

Medicare Part D rebate reporting was the focus of a settlement requiring $101 million in fixed payments from Rite Aid and Elixir Insurance Company in 2024. The government alleged that manufacturer rebates were misreported as service fees, allowing the businesses to retain money that should have reduced Medicare’s costs.

This alleged form of Part D fraud sits at the sponsor-reporting stage. The prescription can be real. The alleged falsehood concerns what the drug ultimately cost and what the sponsor told CMS. Rebate contracts, fee descriptions, annual reports and payment certifications connect that alleged misreporting to federal reconciliation.

Medicare Overpayments Kept After Identification

Medicare overpayments kept after identification can become a False Claims Act issue when a business knowingly retains money after repayment is due. Internal audit findings, management’s response, corrections and refund records explain that decision.

Part A and Part B overpayments and Part D overpayments follow their own payment and reconciliation rules. An insider may know the crucial fact: management understood why the money belonged back and chose to keep it.
