OA-271: Prior Contractual Reduction on Periodic Payment

What Does OA-271 Mean?

OA-271 is the standard and typically the only group code used with CARC 271. The OA designation indicates this is an adjustment that does not fit standard contractual write-off or patient responsibility categories — it is a financial reconciliation between the provider and payer based on prior contractual terms. The deferred amount was previously reported and is now being applied to the current payment cycle. This is an accounting adjustment, not a clinical denial.

When CARC 271 appears on a remittance, the payer is reducing the current payment by an amount that was previously deferred as part of a contractual payment schedule. This is not a denial of a specific claim for services rendered — it is a retroactive financial adjustment where the payer is recouping amounts that were reported in earlier payment cycles but not yet collected. The deferred amounts were flagged on prior remittances, and the payer is now applying them to the current payment.

This code is primarily used in managed care contracts, capitation arrangements, and settlement agreements where payment schedules include periodic reconciliation. For example, if a payer overpaid during a prior quarter and the contract specifies quarterly reconciliation, the overpayment may be recovered through a CARC 271 adjustment on a subsequent remittance. The code carries Group Code OA because the adjustment does not fit neatly into standard contractual write-off or patient responsibility categories — it is a financial reconciliation between the payer and provider.

Providers who see CARC 271 should treat it as an accounting event rather than a clinical denial. The key action is to verify that the deferred amount being applied matches what was previously reported. Cross-reference the current reduction against prior remittances and your internal records of deferred amounts. If the numbers do not align, contact the payer with documentation showing the discrepancy.

Common Causes

How to Resolve

Verify the deferred amount matches prior remittance records and your contractual payment schedule, then post the adjustment or dispute discrepancies with the payer.

1. Verify the deferred amount Cross-reference the OA-271 reduction against your records of prior remittances and deferred payment reports. Confirm the amount is accurate.
2. Check your contractual payment schedule Review the contract terms that govern periodic reconciliation and deferred payment recovery. Verify the timing and methodology are consistent with the agreement.
3. Contact the payer if the amount is incorrect If the reduction does not match your records, provide the payer with prior remittance copies and your deferred amount tracking records to demonstrate the discrepancy.
4. Post the reconciliation adjustment Record the verified adjustment in your accounting system and mark the deferred amount as settled to close the reconciliation cycle.

How to Prevent OA-271
