How do I fix OHIP error code DG?

Check whether the patient was a hospital in-patient, or was admitted within 24 hours for the same condition. If so, there is nothing to fix. If the patient wasn't a hospital patient, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details such as your chart notes.

When shouldn't I resubmit a DG claim?

The patient was a hospital patient for this service. The claim is already on the RA and you only disagree with the decision. Use an RAI, not a new claim.

Explanation

OHIP didn't pay this line because diagnostic services for hospital patients are covered by the hospital's global budget, not paid fee-for-service.

What it means

Code DG means a diagnostic or miscellaneous service for a hospital patient isn't payable fee-for-service, because the hospital's global budget covers it.

The Schedule says the technical component of a diagnostic service (listed as 'technical component', or in an 'H' or 'T' column) is not eligible for payment when the patient is a hospital in-patient, or attends the hospital for the test and is admitted to the same hospital within 24 hours for the same condition (GP10).

Common causes

A technical component billed for a hospital in-patient
A technical component billed for a test before an admission within 24 hours for the same condition
A wrong in-patient indicator or service location

How to fix it

If the patient wasn't a hospital patient, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details such as your chart notes.

Don't resubmit if

The patient was a hospital patient for this service.
