Z409 – Percutaneous retroperitoneal lymph node biopsy - two or more groups
OHIP Psychiatric Code — HAEMATIC AND LYMPHATIC SURGICAL PROCEDURES · Schedule of Benefits
Percutaneous retroperitoneal biopsy of two or more lymph node groups. This is a surgical procedure with a fee for the surgeon (suffix A), and unit-based fees for the assistant (suffix B) and anaesthetist (suffix C).
When to Use
- Use Z409 when performing a percutaneous biopsy on two or more distinct retroperitoneal lymph node groups during a single operative session.
- Select Z409 instead of Z407 when the clinical requirement necessitates sampling multiple anatomical lymph node regions rather than a single site.
Common Pitfalls
- Billing Z409 alongside Z407 for the same procedure is a common error; Z409 is intended to encompass the complexity of multiple sites.
- Failure to document the specific anatomical locations of the two or more lymph node groups will lead to audit recovery, as the code definition requires evidence of multiple distinct groups.
Billing Tips
- Ensure the operative report explicitly details the sampling of at least two separate lymph node groups to justify the higher complexity fee compared to single-site codes.
