OHIP explanatory code MA
Maximum number of sessions has been reached
What MA means
The Ministry of Health’s official wording for MA is: “Maximum number of sessions has been reached.”
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 MA
The fee was reduced or capped under this rule. If you believe the full amount was payable, file a Remittance Advice Inquiry with supporting detail.
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.
