Cracking the Code
DIEP Breast Reconstruction
With a deep inferior epigastric perforator (DIEP) procedure, fat, skin, and blood vessels are cut from the wall of the lower belly and moved up through a person’s chest to rebuild the breast. When coding a DIEP procedure, it is important to remember that the harvesting of the flap is NOT coded separately. With this procedure, the “Replacement” code fully specifies the fact that an autograft was harvested, and the qualifier value describes the DIEP flap.
Q: A 42-year-old female patient who is post mastectomy secondary to breast cancer was admitted for left breast DIEP flap reconstruction with nerve conduit neurotization. The surgeon dissects the abdominal fascia and harvests the perforator flap. The nerve repair is accomplished using a Neurogen alloplastic conduit. The ends of the nerves were secured to the conduit with a suture. Patient tolerated procedure well.
