Explanation
Updated October 26, 2026
DH explains a payment: OHIP allowed ventilatory support together with haemodialysis for the patient. There is usually nothing to fix.
What it means
DH appears on the Remittance Advice (RA) when OHIP allows a ventilatory support fee together with a haemodialysis service. It explains why both services were paid. It is not a rejection.
In the Schedule of Benefits, ventilatory support in an intensive care area is billed with the per diem codes G405 (first day), G406 (days 2 to 30) and G407 (day 31 onward) (page J31). Acute haemodialysis is listed separately, for example G325 and G323 (page J37).
How to fix it
- Check the amount paid on the line against what you billed.
- If it was paid as expected, there is nothing to do.
- If you think the payment is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting 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.
