Z198 – Toes
OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Service for the application of a cast, classified as a musculoskeletal surgical procedure. As per the rules on page of the Schedule of Benefits, this procedure can be delegated. When delegated, it must be performed by a physician's employee in the physician's office, and the physician must be physically present in the office, with some exceptions. See the 'Delegated Procedure' section on pages and for full requirements.
When to Use
- Use Z198 for the initial application of a cast to the toes following a fracture or soft tissue injury requiring immobilization.
- Use this code when a cast is applied by a physician's employee in the office under the physician's physical presence as a delegated procedure.
Common Pitfalls
- Billing Z198 for a simple splint or dressing, which are not considered casts and may be rejected or subject to recovery upon audit.
- Failing to document the specific identity of the non-physician staff member who performed the delegated procedure, which is a mandatory requirement under GP62.
- Attempting to bill an office visit fee (e.g., A007) in addition to Z198 on the same day without a separate, distinct, and medically necessary assessment unrelated to the casting procedure.
Billing Tips
- Ensure the medical record contains a clear, dated note detailing the procedure performed by the delegate to satisfy the documentation requirements for delegated services.
- Verify that the casting material and application meet the definition of a musculoskeletal surgical procedure to avoid confusion with basic nursing or dressing supplies.
