Z243 – Tenotomy - closed - more than one toe
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is for the performance of a closed tenotomy, which is the surgical division of a tendon without a large skin incision, on more than one toe. It is a surgical procedure listed under the Musculoskeletal System section of the Schedule of Benefits. An anaesthetic service is payable with this procedure.
When to Use
- Use Z243 when performing a closed tenotomy on two or more toes during the same operative session.
- Use this code for percutaneous tendon releases where no formal open incision is required for the multiple toes treated.
Common Pitfalls
- Billing Z243 for a single toe; if only one toe is treated, you must use Z229 instead.
- Attempting to bill Z243 in addition to Z229 for the same foot; the code Z243 is intended to cover the multiple-toe procedure in its entirety.
- Failure to document the specific toes treated, which is essential for audit purposes to justify the 'more than one toe' requirement.
Billing Tips
- Ensure the operative report clearly identifies the number of toes involved to support the use of the plural code Z243 over the singular Z229.
- If an anaesthetist is involved, ensure they record the exact start and end times in the patient record, as this is a mandatory requirement for anaesthesia billing under GP7.
