OHIP Error Report code CNA

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.
What to do depends on the claim
The right fix depends on the details of the claim. Read the ministry's description closely, compare it with what was submitted, and correct whichever field it points to.
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.
