CO-263: Adjustment for Shipping Cost (Pharmaceuticals Only)
CO-263 is a contractual adjustment to pharmaceutical shipping charges. Verify the payer's shipping policy and resubmit with corrections if applicable.
What Does CO-263 Mean?
When paired with Group Code CO, the pharmaceutical shipping cost adjustment is a contractual obligation. The provider absorbs the shipping cost difference and cannot transfer it to the patient.
CARC 263 is a pharmaceutical-specific adjustment that addresses shipping costs associated with drug delivery. When a pharmacy or provider bills for shipping medications to a patient, the payer may adjust the charge based on plan coverage, fee schedule limits, or documentation requirements.
This code applies exclusively to pharmaceutical shipping — not to general medical supply or equipment shipping. The adjustment may reflect that shipping costs are not separately reimbursable under the plan, that the billed amount exceeds the payer's maximum allowed shipping charge, that the shipping cost was bundled into the drug cost and should not be billed separately, or that required documentation (shipping receipts, invoices) was not provided.
Shipping cost coverage for pharmaceuticals varies widely. Some plans reimburse actual shipping costs up to a maximum, others bundle shipping into the drug price, and some exclude shipping charges entirely. Verify your payer's specific policy before billing shipping separately.
Common Causes
| Cause | Frequency |
|---|---|
| Pharmaceutical shipping costs not covered under plan The payer's plan does not cover or reimburse shipping costs associated with pharmaceutical products | Most Common |
| Shipping cost included incorrectly in pharmaceutical claim Shipping costs were mistakenly included in the claim when they should not be billed separately or are bundled into the drug cost | Common |
| Missing documentation for shipping charges Insufficient evidence justifying pharmaceutical shipping costs such as shipping invoices or receipts | Common |
| Shipping cost exceeds allowed maximum The billed shipping amount exceeds the payer's maximum allowable amount for pharmaceutical delivery | Occasional |
How to Resolve
- Review payer policy on shipping costs Check whether the payer reimburses pharmaceutical shipping separately.
- Verify coding Confirm pharmaceutical and shipping codes are correct.
- Provide shipping documentation Include shipping invoices and receipts with the corrected claim.
- Resubmit or appeal Correct the claim and resubmit, or appeal with comprehensive shipping documentation.
If pharmaceutical shipping costs should be covered under the contract, file an appeal with shipping invoices, receipts, contract provisions supporting the charge, and documentation of the shipping necessity.
