CO-30 Denial Code Explained

CO-30 is a medical billing denial code that indicates the patient is not covered by the insurance plan on the date of service. This denial commonly occurs when eligibility information is incorrect or insurance coverage is inactive.

What Does CO-30 Mean?

The CO-30 denial code means the insurance payer determined the patient did not have active insurance coverage for the billed services on the reported service date.

This denial is often related to eligibility verification issues, terminated policies, or incorrect insurance information.

Common Reasons for CO-30

• Inactive insurance coverage

• Coverage terminated before service date

• Incorrect patient insurance information

• Billing incorrect payer

• Expired insurance policies

• Eligibility verification errors

How To Fix CO-30

Verify the patient’s active insurance coverage and confirm eligibility for the date of service. Providers may need to obtain updated insurance information, submit the claim to another payer, or discuss payment responsibility with the patient.

Performing eligibility checks before treatment can help reduce future denials.
