CO-271: Prior Contractual Reductions on Current Payment Schedule

What Does CO-271 Mean?

CO-271 indicates the prior contractual reduction is being treated as a standard contractual obligation deduction from the current payment. This may occur when the payer's contract terms specifically classify deferred amount recoveries as contractual adjustments rather than general payment schedule items. The provider cannot pass this amount to the patient.

CARC 271 appears when a payer applies a prior contractual reduction to the current payment period. This code deals with payment schedule mechanics rather than claim-level denials — amounts that were previously deferred, overpaid, or flagged for reconciliation on earlier remittances are now being collected from the current payment.

This code is most commonly seen in capitated or periodic payment arrangements where contractual adjustments from prior periods carry forward. The reduction may reflect deferred amounts that were already reported on previous remittances, reconciliation of overpayments from earlier periods, or contractual payment schedule terms that spread adjustments across multiple payment cycles.

The primary Group Code is OA, reflecting that this is a payment schedule adjustment rather than a standard contractual obligation or patient responsibility issue. CO and PR may appear in less common scenarios involving specific contract terms or patient-level payment adjustments.

How to Resolve

1. Review the contract terms Check the specific contract language that governs how prior reductions are applied to determine if CO is the expected Group Code for this type of adjustment.
2. Verify the deduction amount Cross-reference the CO-271 deduction against prior remittances and your records of deferred amounts to confirm accuracy.
3. Dispute if incorrect If the amount does not match your records, contact the payer with payment history documentation and request correction.
4. Post the adjustment If the deduction is verified as accurate, post it as a contractual adjustment and update your deferred amount tracking records.

How to Prevent CO-271

• Conduct regular internal audits of contractual payment schedules and deferred amount balances
• Maintain comprehensive documentation of all prior contractual reductions and deferred payments
• Track deferred amounts reported on previous remittances to anticipate future reductions
• Establish clear communication with payers regarding contractual payment schedule terms and upcoming deductions
• Implement revenue cycle management software that tracks deferred payments and contractual reduction schedules
