CO-265: Pharmaceutical Administrative Cost Adjustment

What Does CO-265 Mean?

CO-265 classifies the pharmaceutical administrative cost adjustment as a contractual write-off. The payer's contract either excludes administrative fees or caps them at a specified rate, and the provider must absorb the difference. This is the expected pairing for administrative cost adjustments under most payer contracts. The patient cannot be billed for the adjusted amount.

When CARC 265 appears on a remittance, the payer has adjusted the administrative cost portion of a pharmaceutical claim. This code applies exclusively to pharmaceutical billing and covers operational expenses such as dispensing fees, handling charges, processing costs, and other administrative overhead associated with preparing and fulfilling medication orders. It sits alongside CARC 262 (delivery), 263 (shipping), 264 (postage), and 266 (compound preparation) in the family of pharmaceutical-specific cost adjustment codes.

Pharmacies, particularly specialty and compounding pharmacies, encounter this code when payers determine that the billed administrative charge exceeds what the contract allows or when administrative fees are not a separately reimbursable item. Some payers include administrative costs in the overall drug reimbursement rate and will not pay for them as standalone line items. Others may cap administrative fees at a flat rate regardless of the complexity of the dispensing process.

The most common pairing is with Group Code CO, which classifies the administrative cost adjustment as a contractual write-off. The provider cannot pass this charge to the patient under a CO adjustment. Before posting the write-off, verify that the correct billing codes were used and that the administrative charge falls within the payer's allowed parameters. If your contract specifically allows administrative cost reimbursement and the payer adjusted it in error, you have standing to request reprocessing or file an appeal.

Common Causes

How to Resolve

Confirm whether pharmaceutical administrative costs are separately reimbursable under your payer contract, verify billing accuracy, and resubmit or accept the adjustment.

1. Review contract language on administrative fees Determine whether your payer contract includes pharmaceutical administrative costs as a reimbursable charge. Note any caps or documentation requirements.
2. Correct billing errors if found If administrative charges were incorrectly coded, fix the codes and resubmit. Ensure administrative fees are properly separated from drug costs.
3. Post the adjustment or request reprocessing Accept the write-off if administrative fees are not separately covered. If they are covered and were denied in error, request reprocessing with supporting documentation.

How to Prevent CO-265

• Maintain a reference of which payer contracts allow separate pharmaceutical administrative fee billing
