R306 – Bone - Tarsal bar
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R306 represents the surgical excision of a tarsal bar. This procedure falls under the Musculoskeletal System section of the Schedule of Benefits. Payment may be claimed for the surgeon (suffix A), surgical assistant (suffix B), and anaesthetist (suffix C), each with specific billing rules and unit calculations.
When to Use
- Use R306 specifically for the surgical excision of a tarsal bar (coalition) to restore subtalar or midtarsal joint motion.
- Select R306 when the procedure involves the resection of the bony or fibrous bar, distinguishing it from simple arthrodesis codes like R308 or R309.
Common Pitfalls
- Billing R306 in conjunction with other foot/ankle procedures without checking for 'incidental' or 'included' status in the Schedule of Benefits, which can lead to automatic rejections.
- Failing to document the specific anatomical location of the tarsal bar, which is required to justify the surgical approach and complexity of the excision.
Billing Tips
- Ensure that if the procedure is performed bilaterally, the second side is billed with the appropriate 'B' suffix or indicator as per the Schedule of Benefits rules for musculoskeletal procedures.
