Z413 – Scalene node fine needle aspiration
OHIP Psychiatric Code — HAEMATIC AND LYMPHATIC SURGICAL PROCEDURES · Schedule of Benefits
Performs a fine needle aspiration on a scalene lymph node. This procedure is categorized under 'Incision' within the Haematic and Lymphatic Surgical Procedures section of the Schedule of Benefits.
When to Use
- Use Z413 specifically for fine needle aspiration of a scalene lymph node when diagnostic tissue sampling is required for staging or pathology.
- Do not use this code for general lymph node biopsies; use R910 or R912 for excision or incision of other lymph nodes.
Common Pitfalls
- Billing Z413 in addition to a consultation or assessment code on the same day is often flagged unless the procedure is clearly distinct and medically necessary as a separate service.
- Submitting Z413 for a core needle biopsy or open surgical biopsy is incorrect, as this code is restricted to fine needle aspiration techniques.
Billing Tips
- Ensure the procedure note explicitly states 'scalene' location, as generic lymph node aspiration codes will be rejected or audited if the anatomical site is not clearly specified.
