R029 – Scar revision - other areas - greater than 10 cm
OHIP Radiology Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Surgical revision of a scar greater than 10 cm in length, on any area of the body excluding the face or neck. The service fee is for any method of closure. This procedure has 6 base units for an assistant (R029B) and 7 base units for anaesthesia (R029C). As per the note on page of the Schedule, prior authorization is required for scar revisions in areas other than the face or neck (see Appendix D).
When to Use
- Use R029 for the surgical revision of a scar exceeding 10 cm in length located on the trunk or extremities, provided you have obtained prior authorization.
- Use this code for complex scar excisions where the primary goal is functional or aesthetic improvement of a non-facial/non-cervical scar that meets the length threshold.
Common Pitfalls
- Billing R029 without obtaining prior authorization as required by Appendix D will result in automatic claim rejection.
- Confusing R029 with R028 (scar revision 5-10 cm) or R027 (scar revision < 5 cm); ensure the measured length of the scar exceeds 10 cm before billing.
- Attempting to bill R029 for facial or neck scars; these areas are specifically excluded and require different codes from the Schedule.
Billing Tips
- Always document the exact length of the scar in the operative report to justify the use of R029 over the shorter scar revision codes.
- Ensure the prior authorization reference number is available or noted in your records, as it is a mandatory prerequisite for this specific procedure code.
