How do I fix OHIP error code ESD?

Check whether the service was given in an emergency department under an alternative funding agreement. If you worked a shift there, submit it under that agreement's arrangements, not as a regular fee-for-service claim. If you are the patient's family physician and were called in, consider A100 with the department's master number. Resubmit the corrected claim within three months of the service date. If that window has passed but the claim was first submitted on time, use the Ministry's stale-dated resubmission process.

Code: ESD
Description: Emergency department under APP funding on service date

Explanation

Updated October 26, 2026

ESD means the emergency department was under an alternative funding agreement on the service date, so the claim isn't payable as billed.

What it means

ESD means the hospital emergency department where the service was given is part of an alternative funding agreement, and your group affiliation on the service date means the claim is not payable as billed.

In an emergency department funded under an Emergency Department Alternative Funding Agreement (ED-AFA), physician work in the department is funded through the agreement. The patient's own family physician who is called in may bill A100 instead (Schedule A7, GP41).

Common causes

Emergency department work billed fee-for-service by a physician affiliated with the hospital's ED funding group
The wrong group or billing number on the claim
