Z247 – Tenotomy or fasciotomy (closed) - Finger - one
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
A closed tenotomy or fasciotomy performed on one finger. As a surgical procedure, this service is subject to the general rules for surgical procedures, including common elements (, ), suffix usage (), anaesthesia calculation (-), and supervision of medical trainees (-).
When to Use
- Use Z247 for a single-digit closed tenotomy or fasciotomy, such as a percutaneous release of a trigger finger.
- Use Z247 when performing a single-site procedure; if you treat a second finger during the same session, you must switch to Z248, or Z249 for three or more.
Common Pitfalls
- Billing Z247 alongside a consultation or assessment on the same day without a valid diagnostic code or explicit documentation of a separate, identifiable service.
- Attempting to bill for a surgical assistant using this code, as Z247 is explicitly ineligible for assistant fees unless prior authorization is obtained via M400B.
Billing Tips
- Always append the appropriate suffix (e.g., LT, RT) to Z247 to specify the anatomical location, as this is a surgical procedure subject to GP10 rules.
- If the procedure is performed in an emergency or after-hours setting, ensure you meet the non-elective criteria before applying E409 or E410 premiums to the $49.20 base fee.
