How do I fix OHIP error code 45?

Look up the fee code in the Schedule of Benefits and check which specialties may bill it. If the physician is registered in a specialty that can bill it, the claim should carry that specialty. Otherwise, find the equivalent code in the physician's own specialty listing, if one fits. If the claim is on the RA, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, rather than a new claim.

When shouldn't I resubmit a 45 claim?

The physician has no registered specialty that can bill the code, and no other code fits. The claim is already on the RA. Changes to a claim on the RA go through an RAI, not a new claim.

Explanation

Updated October 26, 2026

The fee code can only be paid to certain specialties, and the specialty on the claim isn't one of them.

What it means

Code 45 means there is a specialty code restriction on the fee code. OHIP didn't pay it because the specialty billed isn't allowed to claim that code.

Specialists bill from the listings for their own specialty. When a specialist provides a service outside the scope of their specialty, the Schedule has its own rules for how it is paid (General Preamble GP9–GP10).

Common causes

A code from another specialty's listing billed under the physician's specialty
The wrong specialty code on the claim, for a physician registered in more than one
A typing error that turned the fee code into one reserved for another specialty
