M143 – Lobectomy
OHIP Ophthalmology Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Lobectomy is the surgical removal of a lobe of the lung. The procedure may include radical mediastinal node dissection or sampling. The fee for this procedure includes the standard components of a surgical service as defined in the Surgical Preamble (), such as pre-operative assessment (excluding the major pre-operative visit), the surgical procedure itself, and post-operative care for up to two weeks. Payment for the surgeon (`M143A) is a flat fee. Payment for the assistant (M143B) and anaesthetist (M143C) is calculated based on base units plus time-based units. The assistant service has 10 base units (:645), and the anaesthesia service has 13 base units (:645).
When to Use
- Use M143 for the standard surgical resection of a lung lobe, including cases where radical mediastinal node dissection or sampling is performed.
- Use M143 in conjunction with E683 when the procedure is performed via VATS, robotic-assisted surgery, or a uniportal approach to capture the 35% fee increase.
- Use M143 with E644 specifically when performing a radical mediastinal node dissection on a patient who has received prior chemotherapy or radiotherapy.
Common Pitfalls
- Attempting to bill a second surgical assistant without prior authorization from a medical consultant, as M143 is not on the pre-approved list for a second assistant.
- Failing to document the specific BMI in the patient's permanent record when attempting to claim the E676A or E676B morbid obesity add-ons.
- Incorrectly applying E676A or E676B when the procedure is performed thoracoscopically, as these add-ons require an open surgical technique.
Billing Tips
- Ensure the 14-day post-operative care period is accounted for, as all standard post-operative visits are included in the M143 flat fee.
- Always verify if the procedure qualifies for E409 or E410 premiums for non-elective cases occurring after hours, as these are calculated as a percentage of the M143 base fee.
