CO-242: Services Not Provided by Network Provider
Services/procedures not provided by network/primary care providers.
Why Claims Get Denied with CO-242
Denial code CO-242 is triggered when services/procedures not provided by network/primary care providers. Understanding the root causes helps prevent future denials and strengthens your appeal when one occurs.
Provider is out of network for the patient's plan
Patient did not obtain required referral from PCP
HMO plan requires in-network provider for the service
Provider credentialing with the payer is not complete
How to Appeal CO-242
If you are in-network, provide your contract or credentialing documentation. For emergency services, cite the No Surprises Act and state balance billing protections. If the patient had no reasonable in-network alternative, document that and request a network gap exception.
Documentation Required for Appeal
A successful appeal of CO-242 requires thorough documentation. Gather these items before drafting your appeal letter:
Provider contract or credentialing confirmation
No Surprises Act applicability documentation
Network gap exception request with evidence
Emergency service documentation
How to Prevent CO-242 Denials
Verify your in-network status with each payer regularly. Confirm patient plan type (HMO, PPO, EPO) during registration. Complete credentialing before seeing patients under new payer contracts.
