PR-B7 denial code
Provider was not certified or eligible to be paid for this procedure on this date of service
How to fix it
Check enrollment effective dates. If enrollment was later made retroactive, resubmit. If not, the revenue is generally unrecoverable.
How to prevent it
Begin credentialing well before a provider's start date and do not schedule payer-specific patients until enrollment is effective.
In practice
A practice hires a new physician who starts seeing patients on the first of the month. Claims go out normally for six weeks. Then a batch returns PR-B7: the provider was not certified or eligible to be paid for these services on those dates.
Credentialing was submitted, but the payer's enrolment effective date is three weeks after the start date. Every claim in that window is denied, and because the denial is about enrolment rather than the claim, correcting and resubmitting changes nothing.
The only recovery is retroactive enrolment, which some payers grant and many do not. Where it is refused, six weeks of a physician's production is unrecoverable — which is why this denial is discussed as a scheduling decision rather than a billing one.
What sits behind it
PR-B7 is the most expensive preventable denial in medical billing, because it does not affect one claim. It affects every claim a provider submits to that payer until enrolment is effective, and the volume accumulates silently for weeks before the first remittance reveals it.
The compounding factor is timing. Commercial credentialing commonly runs 90 to 180 days, and the effective date is set by the payer, not by the practice. A provider who starts before enrolment is effective is generating accounts receivable that may never convert, and the practice usually does not find out until the denials arrive in bulk.
The operational answer is not faster credentialing, which is largely outside the practice's control. It is to hold that payer's patients off the new provider's schedule until enrolment is confirmed effective and loaded, and to route them to an enrolled provider in the interim. That is a scheduling rule, and it is the only reliable defence.

Questions about PR-B7
Only through retroactive enrolment, which is at the payer's discretion. Some payers backdate to the application date, some to the credentialing committee approval date, and some refuse entirely. Where retroactive enrolment is granted, the claims are resubmitted; where it is not, the revenue is lost.
They describe the same underlying problem from slightly different angles. PR-B7 states the provider was not certified or eligible to be paid on that date of service; CO-185 states the rendering provider is not eligible to perform the service billed. Both usually resolve to a credentialing gap rather than a coding error.
Commercial payer credentialing commonly runs 90 to 180 days, and the effective date is set by the payer rather than the practice. That gap is why a provider's start date and their billable date should be treated as two different dates.
Do not schedule a payer's patients with a provider until enrolment with that payer is confirmed effective and loaded in the billing system. Begin credentialing months before the start date and route affected patients to an enrolled provider until then.
