CO-265: Adjustment for Administrative Cost (Pharmaceuticals Only)
CO-265 is a contractual adjustment to pharmaceutical administrative charges. Verify coverage and coding, then appeal with documentation if the charge is legitimate.
What Does CO-265 Mean?
When paired with Group Code CO, the pharmaceutical administrative cost adjustment is contractual. The provider absorbs the adjustment and cannot transfer it to the patient.
CARC 265 is a pharmaceutical-specific adjustment for administrative costs associated with dispensing or processing medications. This covers the overhead and administrative expenses a pharmacy incurs beyond the drug cost itself — processing fees, dispensing labor, clinical review, and related administrative activities.
The adjustment may occur because the plan does not reimburse administrative costs separately (they may be included in the drug reimbursement), the billed amount exceeds the payer's maximum allowable administrative fee, coding was incorrect, or supporting documentation was insufficient. Some payers bundle administrative costs into the dispensing fee, while others allow separate billing up to a maximum amount.
Common Causes
| Cause | Frequency |
|---|---|
| Pharmaceutical administrative costs not covered under plan The payer's plan does not cover or reimburse administrative costs associated with pharmaceutical dispensing or processing | Most Common |
| Incorrect coding for pharmaceutical administrative charges Wrong pharmaceutical code assignment on the claim caused the administrative cost to be denied or adjusted | Common |
| Insufficient documentation for administrative charges Missing supporting materials required by the insurer to justify pharmaceutical administrative costs | Common |
| Administrative cost exceeds allowed maximum The billed administrative cost for pharmaceuticals exceeds the payer's maximum allowable amount | Occasional |
How to Resolve
- Review claim for administrative cost appropriateness Confirm the charge is properly associated with pharmaceutical services.
- Verify documentation Check that supporting materials meet the payer's requirements.
- Evaluate coding Ensure the correct codes are used.
- Appeal if warranted Submit an appeal with documentation of administrative expenses and contract provisions.
If pharmaceutical administrative costs should be covered under the contract, file an appeal with documentation of administrative expenses, contract provisions, and a detailed breakdown of the charges.
