E010C – Anaesthetic extra units for patient with BMI > 40
OHIP Surgical Assists Code — GENERAL PREAMBLE · Schedule of Benefits
E010C is an extra unit premium payable in addition to basic and time units when an anaesthesiologist administers an anaesthetic to a patient with a body mass index (BMI) greater than 40. These 2 extra units are added to the total unit count for the anaesthetic service. Per , BMI is calculated by dividing the patient's weight (in kilograms) by the square of the patient's height (in metres).
When to Use
- Use E010C when the patient's BMI is strictly greater than 40, calculated as weight in kg divided by height in meters squared.
- Apply this code in addition to your base anaesthetic units and time units for any elective or emergency procedure where the patient meets the BMI threshold.
Common Pitfalls
- Failure to document the specific height and weight in the anaesthetic record is the primary cause for audit recovery of this premium.
- Do not confuse E010C with ASA physical status premiums like E022C or E017C; E010C is strictly for BMI and is billed independently of the patient's ASA status.
Billing Tips
- Ensure your billing software or manual entry adds these 2 units to the total unit count before multiplying by the anaesthesiologist unit fee.
- Always record the BMI calculation directly in the patient's chart notes to provide immediate substantiation for the E010C claim.
