How do I fix OHIP error code AH?

Find the health exam paid for this patient and compare it with the refused line: date, physician and service. If the refused service was part of the health exam, there is nothing to fix. If it was a separate, medically necessary service for a different problem, check the Schedule rules for both codes and make sure your chart shows the separate service. If you believe the line should have been paid as billed, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details such as your chart notes.

When shouldn't I resubmit a AH claim?

The refused service was part of the health exam. The claim is already on the RA and you only disagree with the decision. Use an RAI, not a new claim.

OHIP didn't pay this service because it was billed in addition to a health exam for the same patient. Check whether it was part of the exam.

What it means

Code AH appears on the Remittance Advice when a service is refused because it was billed in addition to a health exam. The Ministry's description gives no more detail about which services it covers.

In family practice the health exam is usually the periodic health visit (K017, K130, K131, K132 or K133). It already includes an age- and gender-appropriate history, physical exam, health screening and counselling (GP21), so other services that cover the same ground may not be paid on top of it.

Common causes

A separate assessment billed for the same encounter as the health exam
Screening advice or counselling that is already part of the health exam billed as its own service

How to fix it

If the refused service was part of the health exam, there is nothing to fix.

If you believe the line should have been paid as billed, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details such as your chart notes.
