Typical Clinical Scenarios

A 62-year-old woman with a recently diagnosed, multifocal invasive ductal carcinoma involving multiple quadrants of the left breast elects to undergo definitive surgical management. Preoperative imaging and biopsy support that complete removal of the left breast is indicated; no immediate reconstruction is planned during the same operative episode. An open resection is performed to remove all breast tissue on the left side to achieve oncologic control. Typical codes: 0HTU0ZZ
A 48-year-old woman presents urgently with a rapidly enlarging, necrotic mass and superimposed cellulitis of the left breast causing systemic inflammatory response despite antibiotics. Because breast-conserving options are not feasible and the infection involves most of the breast tissue, an open procedure is performed to remove the entire left breast to control infection and source. Typical codes: 0HTU0ZZ
A 70-year-old woman with a prior partial mastectomy on the left side has recurrent extensive disease identified on imaging and biopsy that cannot be adequately treated with re-excision. The surgical plan is completion removal of the remaining left breast tissue without placement of implant or flap reconstruction during the same hospitalization. An open resection of the left breast is carried out to achieve local control. Typical codes: 0HTU0ZZ
