OHIP Error Report code A1A
Outside Service Period
Ontario Ministry of Health, Error Report Rejection Conditions
Where you’ll see it
On your Error Report. The claim was rejected before OHIP assessed it. Error Reports arrive within about 48 hours of a submission.
The fee code doesn't fit this claim
The service code billed doesn't fit the claim as submitted: wrong for the date, the patient, or the other codes on the same claim. Check the Schedule of Benefits rule for the code, choose the one that matches what was done, and resubmit.
A rejected claim was never assessed, so the corrected claim goes back in as a new submission. The three-month limit still runs from the date of service, and a rejection doesn't reset it.
Our summary is a guide, not a ruling. The ministry’s wording and the current Schedule of Benefits are what OHIP applies. See OHIP Error Report vs Remittance Advice: reading the codes for how the two reports differ.
