M144 – Segmental resection, including segmental bronchus and artery
OHIP Ophthalmology Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Segmental resection is the surgical removal of a specific segment of a lung lobe, which includes the segmental bronchus and artery that supply it.
When to Use
- Use M144 for the anatomical resection of a specific lung segment, which must involve the ligation and division of the segmental bronchus and its corresponding segmental artery.
- Select M144 when performing a formal segmentectomy for early-stage lung malignancy or benign disease, as opposed to a wedge resection which does not require formal segmental bronchial and arterial dissection.
Common Pitfalls
- Billing M144 for a wedge resection is a common audit risk; ensure the operative report explicitly confirms the dissection and division of the segmental bronchus and artery.
- Failure to append E683 when performing the procedure via VATS or robotic-assisted approach results in a significant loss of the 35% premium.
Billing Tips
- Always verify that the BMI is documented in the chart before claiming E676A for morbidly obese patients, as this is a frequent target for post-payment recovery audits.
- Remember that M144 includes 14 days of post-operative care; do not bill routine follow-up visits within this window unless they fall under the specific exceptions like C124.
