QUESTION 10
A patient with left breast cancer presented for bilateral skin and nipple sparing mastectomies with Goldilocks reconstruction. After the removal of the breast tissue, dermal autografts/flaps were created and tacked superomedially to create breast mounds. The medial inferior dermal flap was tacked on the pectoralis muscle in the upper inner quadrant and the lateral inferior dermal flap was tacked on the pectoralis in the central portion of the pectoralis muscle. The edges were brought together with staples creating small breast mounds consisting of dermal graft under the mastectomy incision prior to closing the mastectomy flaps. What is the correct code assignment for a mastectomy with Goldilocks reconstruction?
ANSWER
Assign CPT code 19303, Mastectomy, simple, complete, with modifier 50, Bilateral Procedure, for the bilateral mastectomies. Assign CPT code 14000, Adjacent tissue transfer or rearrangement, trunk; defect 10 sq cm or less, or code 14001, Adjacent tissue transfer or rearrangement, trunk; defect 10.1 sq cm to 30.0 sq cm, with the number of units of CPT code 14001 based on the documented square centimeters, for the reconstruction. In a Goldilocks reconstruction, redundant mastectomy flap tissue is utilized to create a breast mound and the technique may be captured with an adjacent tissue transfer code.
