M142 – Pneumonectomy
OHIP Ophthalmology Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Pneumonectomy is the surgical removal of an entire lung. This procedure may also include radical mediastinal node dissection, lymph node sampling, or resection of the pericardium requiring repair. As a non-Z code surgical procedure, the fee includes pre-operative hospital visits one or two days prior to surgery and post-operative care for up to two weeks following the surgery, with the exception of the first and second post-operative visits and the MRP day of discharge visit (C124), which are separately payable. For further details, see the Surgical Preamble ().
When to Use
- Use M142 for the complete surgical removal of an entire lung, which inherently includes radical mediastinal node dissection or lymph node sampling.
- Use M142 when the procedure involves resection of the pericardium requiring repair, as this is considered part of the base procedure.
Common Pitfalls
- Billing for routine post-operative hospital visits within the 14-day post-operative period is a common rejection; only the first and second post-operative visits and the C124 discharge visit are separately payable.
- Failing to document the specific use of an intercostal muscle bundle, pericardium, Azygos vein, or pericardial fat pad will result in the denial of the E609 add-on code.
Billing Tips
- Always append E683 when performing the pneumonectomy via VATS, robotic-assisted, or uniportal approach to secure the 35% fee increase.
- Ensure the E644 add-on is only applied when radical mediastinal node dissection is performed specifically following pre-operative chemotherapy or radiotherapy.
