Z238 – Tenotomy - closed - multiple
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Z238 is for a closed multiple tenotomy of the knee. This involves the cutting of multiple tendons without a large open incision. As a surgical procedure, it includes all common elements of insured services such as pre-procedure evaluation, obtaining consent, and post-procedure follow-up as described in the Schedule of Benefits on -.
When to Use
- Use Z238 for closed, percutaneous release of multiple tendons around the knee when a formal open incision is not performed.
- Select Z238 when the procedure involves multiple tendon releases; do not use it for a single tendon release, which may be covered under different specific codes.
Common Pitfalls
- Billing Z238 alongside an open procedure on the same site is a common audit trigger; ensure the documentation clearly supports the 'closed' nature of the technique.
- Attempting to bill Z238 as an add-on to other major knee surgeries is often rejected as the procedure is considered inclusive of the primary surgical site management.
Billing Tips
- If an assistant is required, use the anaesthetic unit value of 7 as the basis for the assistant's fee calculation as per the Schedule of Benefits.
- Always verify if the procedure meets the criteria for age-based premiums if the patient is under 16, as this is a significant percentage increase on the base fee.
