Z233 – Tenotomy - open adductors
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
`Z233` is a surgical procedure for an open tenotomy of the adductors. As a 'Z' code, it is subject to specific rules regarding admission assessments if performed by a specialist who has recently assessed the patient for the same condition. See for details.
When to Use
- Use Z233 for the surgical release of adductor contractures in patients with cerebral palsy or other spastic disorders where percutaneous methods are insufficient.
- Use Z233 specifically for open surgical approaches; do not use this code for percutaneous tenotomies, which are billed under different procedural codes.
Common Pitfalls
- Billing Z233 alongside an admission assessment code is frequently rejected if the surgeon has already provided a consultation or assessment for the same condition within the restricted timeframe defined in GP23.
- Attempting to bill Z233 bilaterally without the appropriate bilateral indicator or modifier often leads to automatic payment of only one side.
Billing Tips
- Ensure the operative report clearly specifies an 'open' procedure to justify the use of Z233 over less invasive alternatives, as this is the primary audit trigger for this code.
- Always verify if the patient qualifies for the age-based premiums (e.g., AGE_PREMIUM_LT_16Y) as these are significant additions to the base fee of $97.35 for pediatric orthopedic cases.
