Z309 – Biopsy - single
OHIP Psychiatric Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
This procedure is for a single biopsy of the nose. It is classified as an Independent Operative Procedure (IOP), which has specific billing rules regarding pre-operative and post-operative care as detailed on page of the Schedule of Benefits. If a flexible endoscope is utilized during the procedure, the add-on code E839 may be claimed. This service is eligible for age-based premiums for patients under 16 years of age (), after-hours procedure premiums (), and the trauma premium (E420) under specific circumstances ().
When to Use
- Use Z309 for a single diagnostic biopsy of the nasal mucosa or turbinate when performed as a standalone procedure.
- Use Z309 in conjunction with E839 when the biopsy is performed specifically using a flexible endoscope for visualization.
- Use Z309 for biopsies performed in an office or clinic setting where the procedure is the primary service provided.
Common Pitfalls
- Claiming a consultation or assessment fee on the same day as Z309 is restricted; if the major preoperative visit occurred within the last 12 months, only a minor or partial assessment is eligible.
- Failing to account for the 85% rule when performing Z309 alongside other surgical procedures under the same anesthesia, which reduces the benefit for the secondary procedure.
- Attempting to bill Z309 with a hospital admission assessment; as an Independent Operative Procedure (IOP), the assessment is bundled unless it qualifies as the major preoperative visit.
Billing Tips
- Always append E839 to the claim if a flexible endoscope was used to ensure the additional $19.20 flat fee is captured.
- Verify the patient's age at the time of service to automatically apply the appropriate age-based premium (10% to 30%) as defined in GP64.
