BMI Supplements

Surgeons and Anesthesiologists – BMI Supplements for Morbidly Obese Patients

Body Mass Index (BMI) supplemental payments are claimable by the primary Surgeon and the primary Anesthesiologist for certain eligible surgical services on morbidly obese patients.

In order to claim a BMI supplement, the tariff corresponding to the surgical service must be listed under one of the BMI supplement tariffs. The primary Surgeon may claim one of either tariff 0021, 0022, 0023 or 0024 while the primary Anesthesiologist may claim one of tariffs 0025, 0026, 0027 or 0028.
For purposes of these tariffs Morbidly Obese patients are adults with a BMI greater than 40 or a BMI greater than 45 if pregnant. For patients under eighteen (18) years of age, the supplements may be claimed for patients above the 97th percentile for BMI based on an approved paediatric growth curve.
