OHIP explanatory code 35

What 35 means

The Ministry of Health’s official wording for 35 is: “OHIP records show this service rendered has been claimed previously (used on Pay Practitioner duplicate claims).”

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 35

OHIP shows this was already paid - confirm it is not a true duplicate; file a Remittance Advice Inquiry with detail if the service was genuinely separate.

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.
