Need help coding this, the op report is as follows:
Drainage and debridement of infected seroma cavity, removal of infected prosthetic mesh and placement of acellular dermal matrix in onlay fashion
Patient wa moved in to the operating room and placed in supine position. General endotracheal anesthesia was induced. The patient's abdomen was prepped and draped in the usual sterile manner. The previous lower midline incision was opened. Upon entering the subcutaneous tissues, a thick-walled, infected seroma cavity was encountered. Aerobi, anaerobic cultures were obtained. The cavity was extensively debrided of contaminated and necrotic subcutaneous tissue and fat. After this had been adequtely debrided,inspection of the wound revealed the onlay mesh within the infected cavity. At this point the decision was made to remove the infected mesh. As much of the mesh as could possiblu be removed was done so using sharp dissection. After the mesh had been removed, a Zen matrix acellular dermal matrix was chosen and placed overlying the intact mesh in an onlay manner. The mesh was sutured in place using #0 PDS interrupted mattress sutures. The wound was copiously irrigated with sterily saline and carefully instected to ensure adequate hemostasis. A 15-mm Blake drain was placed in the subcutaneous tissues, brought through separate stab wound incisions in the left lower quadrant. The drain was sutured in place using 2-0 silk suture. The subcutaneous tissues were tacked down to the onlay mesh in attempts to obliterate the seroma cavity, using a 2-0 Vicryl interupted sutures. The rest of the subcutaneous tissues wre reapproximated in the midline using 2-0 Vicryl interrupted suture. The skin was closed with skin staples. My doctor wants me to use 15170, 15171 and 11008. I want to use 15330, 15331. and maybe unlisted for the removal of the mesh since CPT 11008 is an add-0n code and needs to be used in conjuction oly with 10180, 11004-11996.
