R100

R100 – Delay, major flap

OHIP Radiology Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits

Delay of a major pedicle flap is a surgical procedure where a large flap of skin and subcutaneous tissue is partially incised and lifted from its bed but not immediately transferred. This process conditions the flap by encouraging an increased and more robust blood supply through its pedicle, improving its viability for a subsequent, definitive transfer to a recipient site.

When to Use

Use R100 when performing the initial stage of a multi-stage pedicle flap procedure where the flap is incised and elevated to improve vascularity before final transposition.
Use this code for the 'delay' procedure itself, distinct from the definitive transfer or inset of the flap, which would be billed under separate codes like R101.

Common Pitfalls

Billing R100 in conjunction with the definitive flap transfer on the same date of service is a common error; these stages must be performed and billed as separate procedures at different times.
Confusing R100 with simple debridement or minor skin excision codes; R100 is specifically for the surgical conditioning of a major pedicle flap.

Billing Tips

Ensure the operative report explicitly details the 'delay' technique, such as the partial incision and elevation of the flap, to justify the use of R100 over simpler integumentary codes.
If the procedure is performed on a pediatric patient, remember to apply the appropriate age-based premium (e.g., AGE_PREMIUM_UNDER_16Y) to maximize the claim value.
