Z249 – Tenotomy or fasciotomy (closed) - Finger - three or more
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Tenotomy or fasciotomy (closed), for three or more fingers. This is a surgical procedure for the release of a tendon or fascia without making a large skin incision.
When to Use
- Use Z249 specifically for closed tenotomy or fasciotomy procedures involving three or more fingers simultaneously.
- Select this code when performing percutaneous release of contractures where no open incision is required for the three-finger threshold.
Common Pitfalls
- Billing Z249 for fewer than three fingers; Z247 and Z248 are the designated codes for single or two-finger procedures respectively.
- Attempting to bill Z249 in conjunction with Z247 or Z248; these codes are mutually exclusive and will trigger an automatic rejection.
- Failing to document the specific fingers treated, which is essential to justify the 'three or more' requirement during an audit.
Billing Tips
- Ensure the procedure is strictly closed; any open surgical approach requires different coding and Z249 will be considered an incorrect claim.
- Apply applicable age-based premiums if the patient is under 16, as Z249 is eligible for these percentage increases.
