Reason Code U5065

Description:

The Medicare Beneficiary Identifier (MBI) effective or end date is not within the dates of service submitted on the claim.

Resolution:

Check/verify the beneficiary's entitlement dates. Medicare beneficiaries or their authorized representatives can ask to change their MBI (e.g., MBi is compromised). The Centers for Medicare & Medicaid Services (CMS) can also change an MBI. Eligibility can be verified by:

  • Review the dates of service on your claim.
  • Make any necessary correction and resubmit the claim with the correct eligibility information
