Z248 – Tenotomy or fasciotomy (closed) - Finger - two
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Z248 is for a closed tenotomy or fasciotomy performed on two fingers. This procedure involves releasing a tendon or fascia through the skin without a formal open incision. It is part of a series of codes for this procedure, with Z247 for a single finger and Z249 for three or more fingers. The surgical fee (suffix A) is a flat rate, while the anaesthesia fee (suffix C) is calculated using 7 base units plus time units. Surgical assistance (suffix B) is not explicitly assigned units but may be payable on an Independent Consideration basis as per the general rules in .
When to Use
- Use Z248 when performing a closed tenotomy or fasciotomy on exactly two fingers during the same operative session.
- Select Z248 when the procedure is performed percutaneously without a formal open incision, distinguishing it from open surgical releases.
Common Pitfalls
- Billing Z248 in combination with Z247 or Z249 for the same patient on the same day will trigger an automatic rejection as these codes are mutually exclusive based on finger count.
- Attempting to bill surgical assistant units automatically; since this code has no assigned units, you must use M400B with a supporting letter for Independent Consideration.
Billing Tips
- Ensure the operative report explicitly documents the number of fingers treated to justify the selection of Z248 over Z247 or Z249.
- If an assistant is required, submit M400B alongside the surgeon's letter detailing the clinical necessity to meet the requirements of GP85.
