CO-B7 denial code

Code B7 is a date stamped statement about the provider. On the day you delivered the care, this payer's records did not show the provider as eligible to be paid for it.

The code list's own wording: This provider was not certified/eligible to be paid for this procedure/service on this date of service.

What it means: The payer's provider file did not show this provider as eligible for this service on that date. Enrolment, credentialling, licensure or a specialty restriction all produce it.
Who owes the money: The practice CO normally. Do not bill the patient. A patient cannot owe your fee because your enrolment paperwork was incomplete.
Is appealing worth it: Better handled through enrolment than appeals. Once the record is corrected, ask for the claims to be reprocessed, and ask specifically about the effective date.

Ask about the effective date, not just the status. This is the question that recovers money. Many payers backdate enrolment to the application date rather than the approval date, which makes claims from the waiting period payable on resubmission. Nobody offers this. You have to ask.

Why the payer sent it

Enrolment with the payer had not completed on the date of service.
Enrolment lapsed, usually because a revalidation deadline passed unnoticed.
The provider is enrolled but not for that service or that specialty.
A licence or certification had expired on the payer's record.
The claim carried the wrong provider identifier.
The practice location was not enrolled, although the provider was.

Read the letters in front of the B7

CO-B7: Contractual obligation. The usual pairing, and it should not stay a write-off while the record can still be corrected.
PI-B7: Payer initiated. Not the patient's money.
PR-B7: Patient responsibility. Not defensible on an enrolment problem. Worth a call.

What to do next

Check the enrolment record for the date of service

Status today is not the question. Status on the day you saw the patient is.
If enrolment completed later: ask what effective date they used and whether it can be applied from the application date.
Check for a lapsed revalidation

Revalidation deadlines pass quietly and take the enrolment with them. A run of B7 denials starting on one date is nearly always this.
Verify the identifiers on the claim

Rendering, billing, group and location. A wrong one produces this even for a fully enrolled provider.
Resubmit everything once the record is right

Do not stop at the one claim in front of you. If enrolment was wrong for a period, every claim in that period carries the same denial, and they are all recoverable together.

Codes that get mixed up with B7

Code	How it differs from B7
185	The rendering provider is not eligible to perform the service. About scope rather than enrolment. See CO-185.
170	Payment denied when performed by this type of provider. About provider type rather than the individual. See CO-170.
242	Services not provided by network providers. Network rather than eligibility. See CO-242.
8	The procedure is inconsistent with the provider type or specialty. See CO-8.

Code B7 in dental

Same story as CO-242 and it hits the same practices: those adding associates. Dental credentialling regularly takes months, and every claim for a new dentist in that window is denied.

Ask every payer the backdating question once

Whether a payer backdates enrolment to the application date is a fact about that payer, not about your case. Asking once and writing the answer down tells you which payers you can safely schedule against during credentialling and which you cannot.

Questions people ask about CO-B7

Can I bill the patient for a CO-B7?

No. The care was delivered and the problem is your enrolment record with the payer. A patient cannot owe your full fee because paperwork between you and the plan was incomplete.

Can claims from before enrolment completed be paid?

Often, yes. Many payers set the effective date to the application date rather than the approval date, which makes claims from the waiting period payable on resubmission. This is rarely offered, so ask specifically what effective date was used.
