Incorrect Date of Birth #

A date-of-birth mismatch can prevent the payer from matching the patient or subscriber during eligibility.

What to do #

  1. Determine whether the payer expects the patient or subscriber date of birth in the relevant transaction context.
  2. Compare the stored date with the approved source.
  3. Correct the appropriate patient/subscriber record only when verified.
  4. Rerun eligibility after the correction.
