R913
R913 – Axillary or inguinal lymph nodes - radical resection, unilateral
OHIP Radiology Code — HAEMATIC AND LYMPHATIC SURGICAL PROCEDURES · Schedule of Benefits
This procedure involves the radical surgical excision of axillary or inguinal lymph nodes on one side of the body. It is listed in the Schedule of Benefits under Haematic and Lymphatic Surgical Procedures on page of the section.
When to Use
- Use R913 for a formal radical lymph node dissection in the axillary or inguinal region, typically performed for oncological staging or therapeutic clearance.
- Distinguish this from R914, which is used for the bilateral version of the same radical resection procedure.
Common Pitfalls
- Billing R913 alongside a primary tumor excision (e.g., mastectomy or wide local excision) may trigger a 'multiple procedure' rule reduction; ensure the primary procedure is billed at 100% and the secondary at 50% if applicable.
- Attempting to bill R913 for simple lymph node biopsies or limited sampling is incorrect; those procedures fall under different, lower-valued codes.
Billing Tips
- If a second surgical assistant is required for this procedure, you must obtain prior authorization from a medical consultant and submit a letter of explanation, as R913 is not on the pre-approved list for dual assistance.
