OHIP explanatory code DP

Procedure paid previously allowed at 50% in addition to this procedure-fee adjusted to pay the difference

What DP means

The Ministry of Health’s official wording for DP is: “Procedure paid previously allowed at 50% in addition to this procedure-fee adjusted to pay the difference.”

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 DP

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.
