CO-82 Denial Code (Deactivated): PIP Days

CO-82 reported PIP days on an institutional claim. The official text is only those two words; X12 deactivated the code without naming a replacement.

X12 deactivated CARC82 on October 16, 2003. Payers should no longer use it on new remittances, but it can still appear on older ERAs, corrected claims, and appeals.

What CO-82 meant

The entire official description of CARC 82 is “PIP days.” In the context of institutional remittances, PIP most often stands for periodic interim payment, a Medicare arrangement in which some facilities receive regular payments based on estimated costs rather than claim by claim. A day count tied to PIP would help the facility reconcile those interim payments with actual claims.

X12 never published a definition, though, so treat that reading as the likely one rather than a certainty. It is not the same as personal injury protection in auto insurance, which has its own P-series codes today.

What replaced it

No replacement was named. There is no active CARC that counts PIP days. Codes you may see in related contexts include CO-143 for a deferred portion of a payment, and OA-271 for prior contractual reductions tied to a current periodic payment.

If you still see CO-82

It lives only in historical institutional files. Record it as information, not as a posting line. If you are reconciling interim payments from that era, compare the day count with the payer’s interim payment reports and settlement records.

  • CO-143 (Portion of payment deferred.): Portion of payment deferred, an active code tied to how payments are timed.
  • OA-271 (Prior contractual reductions related to a current periodic payment as part of a contractual payment schedule when deferred amounts have been…): Prior contractual reductions related to a current periodic payment, an active code for periodic payment schedules.
  • OA-23 (The impact of prior payer(s) adjudication including payments and/or adjustments. (Use only with Group Code OA)): Impact of prior payer adjudication, if the value related to other payments.

CO-82 FAQ

Does PIP here mean personal injury protection?

Not necessarily. In institutional Medicare billing, PIP commonly refers to periodic interim payment, a method of paying some facilities in regular installments. The official code text does not define the term, so confirm with the payer if it matters.

Do I need to act on CO-82?

No claim correction is needed. It was a reporting item. Reconcile it with the payer's interim payment records if you are auditing that period.
