Medicare Billing Fraud: Billing Medicare for services that were never performed, or for a quantity of services that exceeds what was actually provided. This includes billing for patients who were never seen, billing for services ordered but not rendered, and billing for equipment that was never delivered.
Medicare Advantage Fraud: Medicare Advantage plans receive payments from the federal government based on the health risk profile of their enrolled patients. Fraud in this area typically involves submitting false or unsupported diagnosis codes to inflate risk adjustment payments. In fiscal year 2025, Seoul Medical Group Inc. agreed to pay over $60 million to resolve allegations that it caused the submission of false diagnosis codes for spinal conditions that patients did not have in order to increase payments from the Medicare Advantage program.
Upcoding: Billing Medicare for a more expensive service or procedure code than was actually provided. For example, billing for a complex office visit when only a brief consultation took place, or coding a routine surgical procedure under a higher-reimbursement code.
Unbundling: Billing Medicare separately for individual components of a procedure that Medicare requires to be billed together under a single code. Providers who unbundle services receive a higher combined reimbursement than they would under the correct bundled billing code.
Phantom Billing: Submitting claims to Medicare for services, visits, or equipment that were never provided to the patient at all. This includes billing for deceased patients, billing for patients who were in a hospital or other facility on the date of the claimed service, and billing for services that exist only on paper.
