M106 – Mediastinal tumour
OHIP Ophthalmology Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Surgical excision of a mediastinal tumour. The fee for the surgeon (suffix <suffix>A</suffix>) is a flat rate. The fee for the assistant (suffix <suffix>B</suffix>) is based on 9 basic units plus time units. The fee for the anaesthetist (suffix <suffix>C</suffix>) is based on 13 basic units plus time units. This procedure may be performed via an open, thoracoscopic, video-assisted thoracic surgery (VATS), or robotic-assisted approach. See E683 for the applicable premium. Reconstruction of the diaphragm with mesh may be claimed separately with E847. Standard surgical pre- and post-operative care rules apply per the Surgical Preamble (, ).
When to Use
- Use M106 for the surgical excision of a mediastinal tumour, regardless of whether the approach is open, thoracoscopic, VATS, or robotic-assisted.
- Use M106 when the primary intent of the procedure is the removal of a mediastinal mass, distinguishing it from M105 (mediastinotomy) or M107 (mediastinal cyst excision).
Common Pitfalls
- Failing to append the E683 premium when performing the procedure via VATS or robotic-assisted approach, which results in a 35% underpayment.
- Attempting to bill E847 for simple closure of the diaphragm; it is only eligible when reconstruction specifically requires mesh or equivalent synthetic material.
- Incorrectly billing M106 for a mediastinal biopsy; if only a biopsy is performed, use the appropriate mediastinoscopy or biopsy-specific code instead.
Billing Tips
- Always ensure the E683 premium is submitted on the same claim as M106A to trigger the 35% increase for minimally invasive approaches.
- If reconstruction of the diaphragm with mesh is performed during the same session, ensure E847 is included as an add-on to maximize the total procedural fee.
