CO-215: Based on Subrogation of a Third Party Settlement
Payment was reduced due to a third-party settlement. Review the settlement terms and accept or negotiate.
What Does CO-215 Mean?
With CO (Contractual Obligation), the subrogation adjustment is contractual. The payer is exercising its right to reduce payment based on the third-party settlement.
CARC 215 indicates that the payer's payment was reduced or denied because a third-party settlement (such as an auto insurance settlement, workers compensation settlement, or personal injury settlement) includes funds designated for the medical expenses billed on this claim. The payer is exercising its subrogation rights to recover or reduce payment because the patient has already received compensation for these services from another source.
Subrogation is the legal right of the insurance company to seek reimbursement from a third party that caused the injury or from settlement funds designated for medical costs. This is common in auto accident cases, slip-and-fall injuries, and workers compensation claims where a third party is financially responsible.
Common Causes
| Cause | Frequency |
|---|---|
| Third party liability settlement received The patient received a settlement from a third party (auto insurance, workers comp, liability) that covers the medical expenses, and the health insurer is exercising subrogation rights | Most Common |
| Auto accident claim with third party recovery The patient was involved in an auto accident and the at-fault party's insurance has settled or is expected to settle the medical claims | Common |
| Workers compensation subrogation Workers compensation has been identified as the responsible payer for the services and the health insurer is subrogating the claim | Common |
| Liability insurance recovery in progress The payer has identified that a third party may be liable for the medical costs and is pursuing subrogation | Occasional |
How to Resolve
- Review settlement documentation Obtain the settlement agreement and allocation details.
- Verify the adjustment amount Confirm the subrogation amount matches the settlement allocation for medical expenses.
- Negotiate if incorrect If the adjustment amount is wrong, submit documentation showing the correct allocation.
Appeal if no third party settlement has been received and no third party liability exists. Include documentation demonstrating the absence of third party involvement, such as a statement from the patient confirming no accident or liability claim. If the subrogation amount is incorrect, provide documentation of the actual settlement amount.

How to Prevent CO-215
- Track third-party liability cases and settlements to anticipate subrogation adjustments

- Bill the correct payer (auto insurance, workers comp, liability insurer) first when third party liability is identified
- Coordinate with the patient and their attorney when a third party settlement is pending
