CO-283: Attending Provider Not Eligible to Direct Care

What Does CO-283 Mean?

CO-283 means the provider is contractually responsible for resolving the attending provider eligibility issue. The claim is denied because the listed attending provider does not meet the payer's requirements to direct care. The patient cannot be billed — the provider must fix the credentialing issue or correct the claim.

CARC 283 indicates the payer determined that the attending provider on the claim does not meet the eligibility requirements to direct patient care. This is a provider credentialing and enrollment issue — the payer's system flagged the attending provider as ineligible based on their records.

The denial can stem from several root causes: expired medical licenses or board certifications, the provider not being credentialed or enrolled with the patient's insurance plan, the provider type not being authorized to direct certain types of care (e.g., a mid-level provider directing inpatient care), or simply the wrong provider NPI being listed on the claim. Employment or contract status changes can also trigger this code if the provider's eligibility was revoked after leaving a practice.

This code primarily affects institutional claims where the attending provider field is critical — inpatient, skilled nursing, and other facility-based claims. The fix depends on whether the issue is a billing error (wrong provider listed) or a genuine credentialing gap (provider needs to renew credentials or enroll with the payer).

Common Causes

How to Resolve

Verify the attending provider's credentials and enrollment, correct any errors on the claim or credentialing gaps, and resubmit.

1. Verify provider information on claim Confirm the correct attending provider NPI and name are listed — a data entry error is the simplest fix.
2. Check credentials and enrollment Verify the provider's medical license, certifications, and payer enrollment are current.
3. Correct and resubmit If the wrong provider was listed or credentials were renewed, correct the claim and resubmit.
4. Substitute eligible provider If the provider type is ineligible for this type of care, determine if another qualified provider can be listed as attending.
5. Appeal with documentation If the provider is eligible and the payer's records are wrong, appeal with current license and enrollment documentation.
