CO-263: Pharmaceutical Shipping Cost Adjustment
Shipping cost is a contractual write-off. Verify contract terms and either appeal if shipping is covered or accept the adjustment.
What Does CO-263 Mean?
CO-263 designates the pharmaceutical shipping cost as a contractual write-off. The payer's contract either excludes shipping as a separately reimbursable charge or caps it at a specific allowed amount. The difference is the provider's responsibility and cannot be billed to the patient.
CARC 263 appears on a remittance when the payer adjusts the shipping cost component of a pharmaceutical claim. This code is restricted to pharmaceutical billing and addresses the charges for physically shipping medication — distinct from delivery (CARC 262), postage (CARC 264), and administrative handling (CARC 265). When you see CARC 263, the payer has either reduced the shipping charge to a lower allowed amount or denied it outright.
Mail-order pharmacies, specialty pharmacies, and providers that ship medications directly to patients encounter this code regularly. The adjustment typically reflects either a contractual limit on reimbursable shipping costs or a determination that the shipping charge is not a separately billable item under the payer's payment methodology. Some payers bundle shipping costs into the drug reimbursement rate and will not pay for shipping as a separate line item.
Under CO, this is a straightforward contractual write-off. The provider absorbs the shipping cost per the terms of the payer contract. Before accepting the adjustment, confirm that the correct billing codes were used and that the shipping charge was not inadvertently applied to a non-pharmaceutical item. If your contract explicitly allows separate shipping reimbursement and the payer denied it, request reprocessing with your contract terms and shipping documentation as evidence.
Common Causes
| Cause | Frequency |
|---|---|
| Shipping costs included on pharmaceutical claim incorrectly Shipping charges were mistakenly bundled into the pharmaceutical claim when the payer expects them to be excluded or billed separately | Most Common |
| Shipping not a covered benefit The patient's plan does not cover pharmaceutical shipping charges, making the billed amount ineligible for reimbursement | Most Common |
| Insufficient shipping documentation Lack of supporting evidence such as shipping invoices, tracking confirmations, or receipts to justify the billed shipping amount | Common |
| Non-pharmaceutical items billed with shipping code The CARC 263 code was applied to a non-pharmaceutical item in error, as this code is restricted to pharmaceutical claims only | Occasional |
| Billing or data entry errors Mistakes in calculating shipping costs or entering shipping charge data on the claim | Occasional |
How to Resolve
Confirm whether shipping costs are separately reimbursable under your payer contract, correct any coding issues, and resubmit or accept the adjustment.
- Review contract shipping coverage Determine whether pharmaceutical shipping is a covered benefit under your contract with this payer. If not, the write-off is valid.
- Correct billing errors if applicable If shipping was coded incorrectly, fix the codes and resubmit. Verify that shipping charges are properly separated from the drug cost.
- Post the contractual adjustment or request reprocessing Accept the write-off if the contract does not cover shipping. If shipping is covered and was denied in error, request reprocessing with supporting documentation.
How to Prevent CO-263
- Maintain a reference of which payer contracts include separate pharmaceutical shipping reimbursement
- Verify shipping cost coverage for each payer before submitting separate shipping charges
- Ensure shipping codes are properly applied only to pharmaceutical shipments
- Audit pharmaceutical shipping billing quarterly to catch recurring issues
General Prevention
- Maintain detailed shipping documentation and records for all pharmaceutical deliveries
- Verify payer-specific guidelines on shipping cost coverage before billing
- Ensure shipping costs are billed only for pharmaceutical items and not incorrectly applied to non-pharmaceutical products
- Implement systematic claim review processes to catch shipping cost errors before submission
- Provide regular staff training on pharmaceutical shipping billing requirements
