Reason Code N5052

Description:

The beneficiary's Medicare ID number, name, sex, or date of birth submitted on the claim does not match the Medicare ID number, name, sex or date of birth in the Common Working File (CWF) eligibility records.

Resolution:

  • Before submitting your claim, verify that the beneficiary's personal characteristics (name, sex or date of birth) and Medicare ID number on your claim matches the eligibility records, or the beneficiary's Medicare card. In addition to the correct spelling of the name, if the last name includes a space, you must also include a space when submitting your claim, or vice versa (e.g., McDonald vs. Mc Donald). Likewise, do not include a comma or a period unless the name appears as such (e.g. John Smith Jr vs. John Smith, Jr.). For additional information and the various systems available for providers to check eligibility, visit the "Checking Beneficiary Eligibility" CGS web page.
  • Other resources that are available to verify the beneficiary's name, sex, date of birth and Medicare ID number include:
