What MA93 means

Some Medicare institutional providers are paid through Periodic Interim Payment (PIP): steady interim payments based on estimated costs, with actual claims used later to reconcile. MA93 labels a claim that is not part of that arrangement. The claim was processed and paid, or adjusted, on its own merits.

For providers not on PIP, MA93 has little practical meaning. For PIP providers, it matters for accounting: these payments are real claim-level payments, not interim reconciliations.

Common causes

  • The service billed falls outside the scope of the provider’s PIP arrangement.
  • The claim was billed under a provider number or bill type that is not covered by PIP.

What to do

  1. Post the payment at claim level instead of against your PIP receivable.
  2. Confirm the claim should be non-PIP. If you expected it to fall under PIP, check the provider number and type of bill.
  3. Share MA93 claims with your reimbursement team so they are handled correctly in cost report reconciliation.
  4. Contact the Medicare contractor if claims you believe are PIP-eligible keep coming back as non-PIP.

How to prevent confusion

  • Keep separate posting rules for PIP and non-PIP remittances.
  • Review MA93 volume periodically; a sudden change can indicate a billing setup issue. An ERA Analyzer summary by remark code helps you see those shifts.

MA93 FAQ

What is Periodic Interim Payment?

PIP is a Medicare arrangement in which some eligible institutional providers receive regular interim payments based on estimated costs rather than payment claim by claim, with reconciliation later.

Why would a claim be non-PIP?

Not all services are covered by a provider's PIP arrangement. Claims for services outside it are processed and paid individually.

Do I need to do anything?

Mostly reconciliation. Make sure non-PIP claim payments are posted separately so they are not double-counted against PIP amounts.
