Denial code CO-B7

What does Denial code CO-B7 mean on a medical bill?

CO-B7 means the plan's records show this provider was not set up to be paid for this service on that day. It is an enrollment problem: paperwork never finished, a credential that lapsed, or a doctor billing under a group they had not been added to yet. The care happened; the payment path was not in place when it did. Because it comes through as a CO line, the contract puts the problem on the provider's side. It is one of the more common reasons a clean, necessary visit ends up unpaid.

What should I watch out for with Denial code CO-B7?

• Ask the billing office whether the provider's enrollment with your plan was active on the date of service
• Ask them to refile once the enrollment is sorted out, and ask for that commitment in writing
• Ask your plan to confirm the provider's network status for that date before any money changes hands
