What MA80 means

MA80 is a Medicare notice tied to a demonstration project where one payment covers an entire encounter. The hospital’s intermediary (now a Medicare Administrative Contractor) paid the hospital for all services, so this claim, often from a physician or other provider involved in the same encounter, is processed for information only. No payment is issued with this notice.

Common causes

  • The hospital participates in a Medicare demonstration that bundles payment for the encounter.
  • Your claim was submitted separately for services already included in that bundled payment.
  • Dates of service overlap with a hospital encounter covered under the demonstration.

What to do

  1. Confirm the encounter matches a hospital stay or visit covered by the demonstration.
  2. Check your agreement with the hospital regarding how professional services are paid under the demonstration.
  3. Write off the line under your internal policy; do not bill the patient.
  4. Contact the Medicare contractor if the dates do not match any hospital encounter, since the claim may have been matched in error.

For how bundled payments show up in remittance data, see reading CARC and RARC codes.
