Lesion Excision, Repair, and Tissue Transfer: What Includes What
The excision–repair–reconstruction chain has a precise inclusion hierarchy, and most plastics coding errors come from billing a layer that's already inside another.
The hierarchy
- Simple repair is included in excision. Lesion excision codes (benign 114xx, malignant 116xx — selected by site and excised diameter including margins) already cover single-layer closure.
- Intermediate (120xx) and complex (131xx) repairs are separately reportable with excision — coded by site group and the summed length of repairs in that group.
- Adjacent tissue transfer (14000–14302) includes the excision. When you close with a flap or rearrangement (rhomboid, bilobed, V-Y), the ATT code — selected by site and defect size in sq cm — is the only code. Never report the excision separately.
Measure and document
Excised diameter (lesion plus margins), repair length by layer, and defect size in square centimeters are the drivers — each belongs in the note as a number. Debridement codes (11042–11047) select by the deepest tissue level removed plus surface area, with add-ons per additional 20 sq cm; the depth must be explicit.
The reconstructive/cosmetic boundary
Purely cosmetic components are not billable to insurance. Blepharoplasty, breast reduction, and panniculectomy are payable on documented functional criteria; contralateral symmetry procedures after breast reconstruction are covered under federal law. Document the functional indication, not just the plan.
Clinical Capture applies the inclusion hierarchy automatically — if the note describes an ATT closure, it won't offer the excision as a separate line.

Always verify codes and values against the current CPT®, ICD-10-CM, and CMS Physician Fee Schedule, follow NCCI edits and payer policy, and confirm with a certified coder before submitting a claim. Document only work that was actually performed.
