How do I fix OHIP error code ADM?

Check the A888 rules on page A5 and the holiday definition on GP3. Remove codes that aren't payable with A888, or bill the visit with the right code if A888 doesn't apply. Resubmit the corrected claim. Resubmit within three months of the service date if you can. If that window has passed but the claim was first submitted on time, use the Ministry's stale-dated resubmission process described under VJ7.

When shouldn't I resubmit a ADM claim?

The claim still pairs A888 with codes it can't be billed with.

Explanation

Updated October 26, 2026

The claim breaks the rules for emergency department equivalent (A888) visits. Check what can be billed with or instead of A888.

What it means

ADM relates to emergency department equivalent visits and other visits. An emergency department equivalent is an office, urgent care, walk-in or extended-hours clinic where only patients without pre-arranged appointments are seen (General Preamble GP3).

A888 is the partial assessment for an emergency seen in such a setting on a Saturday, Sunday or holiday. The Schedule says A888 is the only fee code payable for that service, no premiums are payable with it, and hypnotherapy or counselling by the same physician the same day isn't payable (A5). On the Remittance Advice, DM refers to the same Ministry policy.

Common causes

A888 billed with another visit or a premium
Hypnotherapy or counselling billed the same day as A888
A888 billed on a day that isn't a Saturday, Sunday or holiday
