Explanation
Updated October 26, 2026
DR means OHIP paid this diagnostic service at 50% because it was treated as self-referred. Check the referring physician on the claim.
What it means
DR appears on the Remittance Advice (RA) when a diagnostic service is paid at 50% of the fee because OHIP treated it as self-referred. It explains a reduced payment. It is not a rejection.
The Ministry's description is the only source we have for this rule. Check the payment against the claim before deciding whether to follow up.
How to fix it
- Check the referring physician field on the claim.
- If another physician referred the patient, make sure their billing number was on the claim. Fix your claim settings so future claims carry it.
- If the service was referred by someone else and you think the 50% reduction is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with the referral details.
Don't resubmit if
- The claim is already on your RA. A new claim for the same service will be treated as a duplicate. Use an RAI instead.
