Ask Dr. Z

Patient had a thrombectomy and revision of aorto-bi-femoral graft. After patch angioplasty the patient had exposure of graft, and physician did a sartorius muscle flap to cover the graft. Would this be coded as 14021 or 15738? See op note regarding this enclosed: "Because of the redo nature and the significant amount of prosthetic in the groin, I proceeded with a sartorius flap. This was done in the usual fashion by freeing up the sartorius muscle from the anterior superior iliac spine and turning the sartorius on top of the previously endarterectomized and patched repair. I placed a drain in the lateral portion of the wound. Closed the drain in multiple layers after securing the sartorius flap to the groin."
