R953 – Bone transport - circular external fixation (less than or equal to 6 cm)
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R953 is listed as a surgical procedure within the Musculoskeletal System section of the Schedule of Benefits. As the content for page was not provided, a specific description of the procedure is unavailable. The service is eligible for payment to the operating surgeon (suffix A), a surgical assistant (suffix B), and an anaesthesiologist (suffix C), as per . Fees for assistant and anaesthetist services are calculated based on basic units (specific to the procedure, details not available) and time-based units as defined in and respectively. This procedure may be eligible for various premiums, including: - Age-based premiums for patients under 16 years of age (). - After-hours premiums for non-elective procedures (). - Trauma premium (E420) for severely injured patients ().
When to Use
- Use R953 for the application of a circular external fixation device specifically for bone transport procedures where the transport distance is 6 cm or less.
- Select this code when performing limb reconstruction or deformity correction requiring controlled bone segment movement via a circular frame.
Common Pitfalls
- Billing R953 for bone transport distances exceeding 6 cm, which requires a different procedural code to reflect the increased complexity.
- Failing to document the specific transport distance in the operative report, which is essential to justify the use of the 'less than or equal to 6 cm' code classification during an audit.
- Attempting to bill R953 in conjunction with other musculoskeletal fixation codes that are considered inclusive of the primary procedure without prior review of the Schedule of Benefits' bundling rules.
Billing Tips
- Ensure the operative note explicitly states the measured transport distance to support the selection of R953 over higher-complexity alternatives.
- Verify that all applicable age-based premiums from GP64 are applied if the patient is under 16, as these are calculated as a percentage increase on the R953 procedural fee.
