Remittance Advice · Payment-time (remittance)
OHIP explanatory code AH
Not allowed in addition to health exam
What AH means
The Ministry of Health’s official wording for AH is: “Not allowed in addition to health exam.”
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 AH
This explains a payment adjustment. If you believe the claim was billed correctly, file a Remittance Advice Inquiry within the deadline; otherwise no resubmission is needed.
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.
