R354 – Interdental wiring for temporomandibular joint disorder
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Interdental wiring for temporomandibular joint disorder. This is a surgical procedure listed under the of the Schedule of Benefits. The service has an anaesthesia base unit value of 7.
When to Use
- Use R354 when performing the specific surgical application of interdental wiring to stabilize the mandible for the management of temporomandibular joint (TMJ) disorder.
- Select R354 for patients requiring temporary immobilization of the jaw where non-surgical interventions like splint therapy (Z239) have failed to provide adequate stabilization.
Common Pitfalls
- Do not bill R354 in conjunction with general dental procedures or routine TMJ assessments (Z240), as the Ministry considers these bundled or distinct from the surgical intervention.
- Avoid billing R354 for simple orthodontic stabilization, as the code is strictly defined for the surgical management of TMJ pathology rather than routine dental alignment.
Billing Tips
- Ensure the surgical nature of the procedure is clearly documented to support the claim, as R354 is subject to audit for medical necessity compared to non-surgical TMJ codes like R652.
- Always apply the 15% age premium for patients 65 years or older, as R354 is explicitly classified as a surgical procedure eligible for this enhancement under GP64.
