Reason Code: U5210
Error Description:
The claim rejected because services were provided prior to the beneficiary’s Medicare Part A or Part B entitlement date; therefore, no Medicare payment can be made.
Avoiding/Correcting This Error
Each beneficiary should be screened for eligibility. Part of the eligibility verification process should include ensuring the dates of service fall within the Medicare entitlement period. Use the IVR system, the FISS Provider Online System, or NGSConnex to verify beneficiary eligibility prior to claim submission.
