R308 – Bone - Os calcis, talus
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Surgical procedure for the excision of the os calcis or talus bone. This service is listed under the Musculoskeletal System surgical procedures for the foot and ankle as found on page of the Schedule. The service fee includes payment for the surgeon (R308A), with separate unit-based calculations for the assistant (R308B - 6 base units) and anaesthetist (R308C - 7 base units). Payment for a second assistant requires authorization by a medical consultant. See for details.
When to Use
- Use R308 for the formal excision of the os calcis or talus bone, distinguishing it from lesser procedures like R307 (excision of other foot bones) or R309 (excision of metatarsals).
- Apply this code when the surgical intent is the complete removal of the bone, rather than a partial resection or debridement which may fall under different musculoskeletal codes.
Common Pitfalls
- Billing R308 in conjunction with other foot procedures without applying the multiple procedure rule (GP85/GP93), which mandates that assistant and anaesthetist units are based solely on the major procedure.
- Failing to document the Injury Severity Score (ISS) in the medical record when attempting to claim the E420 trauma premium for this procedure.
Billing Tips
- Ensure the surgical report clearly specifies the bone excised to avoid audit confusion with R307 or R309, as these codes carry different fee values.
- When performing bilateral procedures, remember that the assistant and anaesthetist base units are not additive; they must be calculated based on the primary procedure as per the Schedule of Benefits.
