Hap 51 Authorization Code Verified 90%

When you submit a claim electronically to a Medicare Administrative Contractor (such as Novitas, Palmetto GBA, NGS, or WPS), the payer’s auto-adjudication system checks for a prior authorization number (often referred to as an "auth code" or "reference number"). If that code matches the payer’s records—including patient eligibility, service dates, and authorized procedures—the system returns a HAP 51 status.

Verify auth details before submission. If appropriate, request a new auth covering the actual services.
