OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure for the correction of hallux valgus, such as a Mayo or Keller arthroplasty.

The surgeon's fee (suffix A) is a flat rate, while fees for an assistant (suffix B) and anaesthetist (suffix C) are calculated based on base units plus time units. (Source: :).
When to Use
- Use R304 for definitive hallux valgus correction procedures such as Mayo or Keller arthroplasty when the primary intent is joint reconstruction or resection.
- Select R304 when performing surgical correction of hallux valgus that does not involve the specific osteotomy techniques covered under R355 or R360.
Common Pitfalls
- Billing R304 in conjunction with R355 or R360 is considered unbundling; these codes are mutually exclusive for the same foot.
- Failure to document the specific surgical technique (e.g., Mayo vs. Keller) in the operative report can lead to audit recovery if the procedure performed does not align with the R304 definition.
Billing Tips
- Ensure the operative report clearly distinguishes the procedure from R355 (osteotomy) or R360 (arthrodesis) to prevent automatic rejection during post-payment review.
