R534 – Tendon sheath - incision and drainage
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R534 is a surgical procedure listed in the Haematic and Lymphatic System section of the Schedule of Benefits. As an insured surgical service, it includes all common elements as described in and . When performed by a surgeon (suffix A), it includes pre-operative, intra-operative, and post-operative care. When an assistant is required (suffix B), the service includes all specific elements of surgical assistance as outlined in . When anaesthesia is provided (suffix C), the service includes pre-anaesthetic evaluation, anaesthetic procedure, and post-anaesthetic follow-up as outlined in .
When to Use
- Use R534 for the formal incision and drainage of a tendon sheath infection (tenosynovitis) where the sheath is opened to allow for irrigation and decompression.
- Select R534 when the procedure involves a surgical incision into the sheath, distinguishing it from simple aspiration or percutaneous drainage which may not meet the criteria for this surgical code.
Common Pitfalls
- Do not bill R534 in conjunction with minor procedure codes for simple wound debridement or abscess drainage; R534 is specific to the tendon sheath and carries a higher fee reflecting the surgical nature of the site.
- Avoid billing R534 for simple digital nerve blocks or local anesthetic infiltration, as these are considered inclusive components of the surgical procedure fee.
Billing Tips
- Ensure the operative report explicitly documents the opening of the tendon sheath to justify the use of R534 over generic incision and drainage codes.
- If the procedure is performed in an emergency setting after hours, ensure the appropriate E-series procedural premium is applied to the base fee of $313.60 to maximize reimbursement for non-elective surgical intervention.
