What Does Code 238 Mean?

Group Code CO (Contractual Obligation): The provider has agreed to accept the payer's determination. The patient is generally not responsible for this amount.
Why Does This Happen?
The claim date range includes dates when the patient was not covered.
How to Resolve It
- 1Split the claim into eligible and ineligible date ranges
- 2Resubmit only for the covered dates of service
- 3Bill the patient for the non-covered period
