Knowing which fee codes are available within your specialty is an important aspect of billing correctly.

If you’re an anesthesiologist then submitting claims can be a bit more complicated than other specialties since fee codes don’t always have a set price, as they differ depending on time units or your patient’s BMI.

Thus, it’s really important to make sure you calculate time units correctly in order to avoid rejections.

In an attempt to make things easier, we’ve created a cheat sheet that lists all of the OHIP fee codes available for Anaesthesia. Go ahead and bookmark this page for a quick referencing, or for a downloadable PDF scroll to the bottom.

Here’s what you’ll find in the cheat sheet:
