R009 – Myocutaneous - osseous flaps
OHIP Radiology Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Myocutaneous - osseous flaps e.g. pectoralis major myocutaneous flap with rib graft, trapezius flap with scapula spine. To include closure of donor site defect by any means.
When to Use
- Use R009 for complex reconstructive procedures involving a composite flap that includes both soft tissue (myocutaneous) and bone (osseous), such as a pectoralis major flap with a rib graft.
- Select R009 when the surgical plan necessitates a single-stage transfer of a composite tissue unit to address a significant defect, as opposed to simple skin grafts or basic pedicle flaps.
- Apply this code when the operative report confirms the inclusion of both muscle/skin and bone components, distinguishing it from R008 which covers myocutaneous flaps without the osseous component.
Common Pitfalls
- Billing R009 alongside separate codes for the donor site closure is a common error; the fee for R009 explicitly includes the closure of the donor site defect by any means.
- Failure to document the specific components of the flap (muscle, skin, and bone) often leads to audit rejections, as the code is specific to the 'myocutaneous-osseous' nature of the graft.
- Submitting R009 for simple bone grafts or standard skin flaps is a frequent cause of claim adjustment, as this code is reserved for composite tissue transfers.
Billing Tips
- Ensure the operative report clearly details the harvesting of both the soft tissue and the osseous component to justify the use of this specific code over lower-valued flap codes.
- If the procedure is performed after hours, ensure the appropriate premium (E409 or E410) is linked to the R009 claim to maximize the procedural fee.
