What it means
Medicare Secondary Payer (MSP) rules determine when Medicare pays after another insurer—such as an employer group health plan, workers' compensation, or auto insurance—pays first. If you are actively employed and your employer covers 20 or more employees, your employer's group health plan generally pays first and Medicare pays second. If your employer has fewer than 20 employees or you are retired, Medicare typically pays first. MSP rules protect Medicare from paying costs another insurer should cover. Hospitals and providers must ask patients about other insurance at registration to coordinate benefits correctly. Violating MSP rules can lead to Medicare demanding repayment from providers.
