Z727 – Percutaneous silicone core needle biopsy
OHIP Psychiatric Code — ENDOCRINE SURGICAL PROCEDURES · Schedule of Benefits
Percutaneous silicone core needle biopsy is an incision procedure performed on the thyroid gland. This procedure is eligible for anaesthesia services, calculated with 7 basic units plus time units.
When to Use
- Use Z727 specifically for a percutaneous silicone core needle biopsy of the thyroid gland when a tissue sample is required for histological diagnosis.
- Choose Z727 over fine-needle aspiration (FNA) codes when the clinical intent is to obtain a core specimen rather than just cytological fluid.
Common Pitfalls
- Billing Z727 in conjunction with an office visit code (A007) is a common rejection; surgical procedure fees are intended to be comprehensive of the visit unless a separate, unrelated problem is addressed.
- Attempting to bill Z727 alongside diagnostic ultrasound guidance (e.g., G367) often triggers manual review or rejection if the guidance is not documented as a distinct, medically necessary component of the procedure.
Billing Tips
- Since Z727 does not have assigned surgical assistant units, you must use the 7 basic units assigned to the anaesthesiologist as the basis for claiming surgical assistant services under M400B, provided you obtain prior authorization and submit a letter of necessity.
