Description
Referring physician number required for this ICHSC fee

Explanation

Updated October 26, 2026

EF7 means this ICHSC fee needs a referring physician number on the claim. Add the referring physician's number and resubmit.

What it means

EF7 means the Integrated Community Health Services Centre (ICHSC) fee billed requires a referring physician number, and the claim didn't have a valid one. The claim was rejected.

Common causes

  • The referring physician number was left off the claim
  • The referral number was entered in the wrong field

How to fix it

  1. Find the referring physician on the requisition or referral.
  2. Add their billing number to the claim.
  3. Resubmit. 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.

Don't resubmit if

  • You don't have a referring physician number. Sending it blank again will reject again.
