Adjacent Tissue Transfer
A 67 year old patient status post previous fracture repair and free flap presents now with an infected nonunion fracture of right tibia. Debridement of the bone is scheduled to be performed and a plastic surgeon is called into surgery to re-elevate the 6 square centimeters of free flap so that the orthopedic surgeon can perform the debridement. Following completion of the debridement procedure the plastic surgeon returns to the OR for revision and advancement of latissimus dorsi free flap and advancement of local tissues. What code(s) should we use for the plastic surgeons portion of the procedure? Should the free flap be coded as initial free flap? ...

Article Overview
This premium article discusses how to approach coding for the plastic surgeon’s portion of a postoperative lower-extremity reconstruction case in which prior flap work is revisited during bone debridement and then revised. It is aimed at coders, billers, and clinical documentation staff who handle orthopedic-plastic surgery overlap, flap-related services, and CPT reporting questions. The article focuses on determining the relevant CPT service category, understanding when flap-related work is considered part of the original reconstruction versus a separate adjacent tissue transfer service, and reviewing the scope of the applicable CPT code family.
Why This Topic Matters
Cases involving multiple surgeons and staged reconstructive work are common sources of coding uncertainty. Correctly distinguishing the reported service category affects claim accuracy, compliance, and reimbursement integrity.
