Z231 – Tenotomy or fasciotomy (closed) - palmar or plantar
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Tenotomy or fasciotomy (closed) - palmar or plantar. This is a surgical procedure involving the cutting of a tendon or fascia without a large incision, performed on the palm of the hand or the sole of the foot.
When to Use
- Use for percutaneous needle fasciotomy (PNF) to release Dupuytren's contracture in the palm.
- Use for closed release of plantar fascia contractures or similar minor closed tenotomy procedures on the foot.
- Use when the procedure is performed via needle puncture or small stab incision without formal open surgical exposure.
Common Pitfalls
- Do not bill Z231 in conjunction with open surgical codes like Z247, as Z231 is strictly for closed procedures.
- Avoid billing Z231 for simple trigger finger releases, which are typically covered under specific tendon sheath release codes.
- Failure to document the 'closed' nature of the technique can lead to audit scrutiny if the claim is mistaken for an open fasciectomy.
Billing Tips
- Ensure the operative note explicitly describes the closed technique to justify the use of Z231 over more invasive surgical codes.
- If performing bilateral procedures, ensure the claim is submitted with the appropriate bilateral modifier to reflect the increased work.
