OHIP explanatory code B1

Service Not Eligible for Payment When Delivered by Telephone

What B1 means

The Ministry of Health’s official wording for B1 is: “Service Not Eligible for Payment When Delivered by Telephone.”

This code appears as an explanatory code on your monthly Remittance Advice (RA). It means the claim was adjudicated — paid, reduced, or refused — for the reason below. A claim already on your RA generally shouldn't be blindly resubmitted; follow the suggested action.

How to fix B1

This service isn't payable when delivered by telephone - review the virtual care eligibility rules and file a Remittance Advice Inquiry if you believe the service qualified as delivered. Don't bill the patient unless you've confirmed the service as delivered is genuinely uninsured.

Payment-time codes appear on the monthly Remittance Advice after adjudication. Some are informational, some explain a reduced or refused payment. Where you disagree with the outcome, the usual route is a Remittance Advice Inquiry or written inquiry — not resubmitting the same claim, which can create a duplicate.
