Summary & Overview
CPT 15777: Biologic Implant Reinforcement for Breast or Trunk Soft‑Tissue
CPT code 15777 captures the intraoperative attachment of a biologic implant to reinforce soft tissue of the breast or trunk. This procedure is clinically relevant for reconstructive and reparative surgeries where additional structural support is required, such as post‑mastectomy reconstruction, complex hernia repairs of the chest wall, or revision procedures. Nationally, accurate reporting of this code supports appropriate surgical documentation, reimbursement mapping, and tracking of implant utilization trends.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how the service is described clinically, typical sites where the procedure is performed, and which major payers cover the service in national analyses. The publication provides benchmarks for utilization and reimbursement patterns, highlights relevant coding and billing contexts, and summarizes clinical scenarios where biologic implant reinforcement is applied. Data limitations and missing input fields are noted where applicable; specific ICD‑10 diagnoses, associated taxonomies, and payer‑specific policy language are not available in the input and are identified as such where relevant. This resource is intended to inform clinicians, coding professionals, and policy analysts seeking a national framing of CPT code 15777.
Billing Code Overview
CPT code 15777 describes the attachment of a biologic implant to reinforce soft tissue during a breast or trunk soft‑tissue procedure. The service involves securing a biologic graft or matrix to provide structural support, commonly used in reconstructive or reparative operations of the chest wall and breast.
-
Service type: Surgical reinforcement with biologic implant during breast or trunk soft‑tissue procedures
-
Typical site of service: Hospital operating room or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A 54-year-old woman with a history of left-sided invasive ductal carcinoma undergoes a partial mastectomy with oncoplastic reconstruction. During the breast soft-tissue procedure the surgeon elects to reinforce the inferolateral breast pocket with a biologic implant to support soft-tissue contour and provide additional coverage over the implant and/or native tissue. The procedure is performed in an outpatient ambulatory surgery center under general anesthesia. Intraoperative steps include tumor excision with margin assessment, hemostasis, creation or revision of a subglandular or subpectoral pocket, placement and fixation of a biologic matrix to the chest wall and native soft tissues, and layered wound closure. Typical documentation in the operative note includes the indication, size and type of the biologic implant, fixation technique, laterality, estimated blood loss, specimen description (if applicable), and any concurrent procedures (for example, axillary staging or contralateral symmetrization). Postoperative care instructions, drain management if present, and follow-up plan are documented in the discharge note.
