OHIP Error Report code V18

Invalid Amission/First Visit date

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.

A submission or documentation step

Something about how the claim was submitted needs to change: a missing field, a manual-review indicator, supporting documentation, or prior approval. Follow the instruction in the ministry's description, then 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.
