R411 – Arthrotomy - shoulder
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This code represents a surgical procedure on the musculoskeletal system. As specific details for R411 are not available in the provided context, billing should follow the general principles for surgical procedures outlined in the Schedule of Benefits. This includes rules for calculating fees for the surgeon, assistant, and anaesthetist based on basic and time units.
When to Use
- Use R411 for a formal surgical arthrotomy of the shoulder joint, such as for joint debridement or biopsy, where the procedure is distinct from a simple diagnostic arthroscopy.
- Select R411 when the shoulder joint is surgically opened to address pathology that cannot be managed via percutaneous or arthroscopic techniques.
Common Pitfalls
- Do not bill R411 in conjunction with arthroscopic procedures on the same joint during the same operative session, as this is considered unbundling.
- Avoid billing R411 for minor procedures that are more accurately captured by specific minor surgical codes, as this may trigger an audit for over-billing.
Billing Tips
- Ensure the operative report explicitly describes an open arthrotomy to justify the use of R411 over less invasive diagnostic or therapeutic codes.
- If the procedure is performed on an emergency basis after hours, ensure the appropriate premium (E409 or E410) is appended to the claim to maximize the fee.
