OHIP Error Codes

A key part of medical billing in Ontario is reconciling your OHIP claims. Even the best billing agents experience the occasional error code and rejected claims. It’s frustrating but necessary to ensure payments are fair and accurate.

To help make things easier, we’ve compiled the most common OHIP error codes. You can find the error code using our unprocessed claims report. Each page below has a full explanation of the error and how to fix it. In most cases, you will need to resubmit the claim or complete an RA inquiry.

We’ve grouped the errors into buckets to make it easier to find what may be causing the issue with your claim. Click on the link to jump to the most appropriate section.
