Code
59
Description
WCB claim - practitioner notification

Explanation

Updated October 26, 2026

This claim relates to a WSIB (formerly WCB) case. OHIP is notifying you that the service is a Workers' Compensation matter.

What it means

Code 59 is a practitioner's notification about Workers' Compensation Board claims. The WCB is now the Workplace Safety and Insurance Board (WSIB).

It tells you that OHIP has linked the service to a workplace injury claim. The Ministry gives no further detail.

How to fix it

  1. Check whether the service was for a workplace injury or illness.
  2. If it was, the service is a WSIB matter. Follow WSIB's billing process for it.
  3. If it wasn't work-related, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, explaining why.

Don't resubmit if

  • The service was work-related. Resubmitting to OHIP won't change that.
