R912 – Ileoinguinal, radical resection
OHIP Radiology Code — HAEMATIC AND LYMPHATIC SURGICAL PROCEDURES · Schedule of Benefits
R912 is a surgical procedure for the radical resection of the ilioinguinal lymph nodes. It is listed under the Haematic and Lymphatic Surgical Procedures section. The fee for the surgeon (suffix A) is a set amount, while fees for the surgical assistant (suffix B) and anaesthesiologist (suffix C) are calculated based on basic units plus time units. The basic units are specified in the Schedule of Benefits as 6 for the assistant and 8 for the anaesthetist. See - for assistant fee calculations and - for anaesthetist fee calculations.
When to Use
- Use R912 for the formal radical resection of ilioinguinal lymph nodes, typically performed as part of a lymphadenectomy for malignancy.
- Select R912 when the procedure involves the comprehensive removal of the ilioinguinal nodal basin, distinguishing it from simpler lymph node biopsies or excisions (e.g., R910).
Common Pitfalls
- Billing R912 alongside other lymph node procedures (e.g., R913) without clear evidence of separate, distinct anatomical sites may trigger a rejection for unbundling.
- Failing to document the specific surgical extent of the radical resection can lead to audit scrutiny, as the fee is significantly higher than standard node excisions.
Billing Tips
- Ensure the surgical assistant (R912B) and anaesthesiologist (R912C) claims correctly utilize the specified basic units (6 and 8, respectively) plus time units as per GP85-86 and GP92-93.
