R282 – Bone - Exostosis (dorsal, subungual)
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service covers the surgical removal of a benign bony outgrowth (exostosis) from the foot or under a toenail. This service is listed under the Musculoskeletal System Surgical Procedures section of the Schedule of Benefits. As a surgical procedure, the fee for R282A covers the surgeon's professional service, which includes all constituent and common elements of insured services as described in the General Preamble (e.g., , ). This typically includes a pre-operative assessment, the operation itself, and standard post-operative care. Fees for an assistant (R282B) and anaesthetist (R282C) are claimed separately and are calculated based on basic and time units specified in the Schedule.
When to Use
- Use R282A for the surgical excision of a subungual exostosis causing chronic pain or nail deformity, distinct from simple nail avulsion (e.g., Z105).
- Use R282A for the removal of a symptomatic dorsal bony exostosis on the foot that requires formal surgical dissection and bone smoothing.
Common Pitfalls
- Billing R282A alongside a minor procedure like a simple nail avulsion (Z105) is often rejected as 'included' in the surgical fee; ensure the excision of the bony outgrowth is the primary operative focus.
- Failing to document the specific anatomical location and the nature of the bony outgrowth can lead to audit scrutiny, as R282 is specific to exostosis and not general soft tissue lesions.
Billing Tips
- Ensure the operative report clearly describes the excision of the bony exostosis to justify the R282A fee, as simple soft tissue excision codes (e.g., S060) are not appropriate for bone pathology.
- If the procedure is performed in a hospital setting, verify that the assistant (R282B) and anaesthetist (R282C) claims are submitted with the corresponding base units to avoid processing delays.
