Summary & Overview
HCPCS C9726: Intraoperative Breast Applicator Placement and Removal
HCPCS Level II code C9726 identifies the placement and, if performed, removal of an applicator into the breast for intraoperative radiation therapy as an add-on to a primary breast surgical procedure. This code captures a discrete intraoperative service that supports targeted radiation delivery at the time of lumpectomy or other breast-conserving surgery, and it is consequential for hospital and ambulatory surgical coding, procedural documentation, and bundled payment considerations. Nationally, accurate use of C9726 affects episode-level reporting and facility billing for intraoperative radiation therapy workflows.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the code’s clinical context, typical sites of service, common billing modifiers, and payer coverage considerations. The publication outlines benchmarking concepts, coding guidance nuances, and policy updates that influence reimbursement and claims adjudication for intraoperative radiation therapy add-on services. The content aims to clarify when C9726 is reported in conjunction with primary breast procedures and what clinical activities it represents, supporting coding accuracy and administrative consistency across hospital and ambulatory settings.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult woman diagnosed with early-stage invasive breast carcinoma or ductal carcinoma in situ who is scheduled for breast-conserving surgery (lumpectomy). Intraoperative radiation therapy (IORT) using a localized applicator is planned at the time of the primary surgical procedure. During the operation, the breast surgeon performs the lumpectomy and prepares the tumor bed. The radiation oncologist or trained operative team places the IORT applicator (C9726 — placement and removal of applicator into breast for intraoperative radiation therapy, add‑on) into the surgical cavity, ensuring proper positioning and shielding as required. After device placement, intraoperative radiation delivery occurs (usually billed separately by the radiation service or device-specific code), then the applicator is removed prior to surgical closure if removal is performed. Typical perioperative workflow includes preoperative multidisciplinary planning, intraoperative coordination between surgery and radiation oncology/physics, documentation of applicator placement and removal times, and inclusion of this service as an add‑on to the primary breast procedure in the operative report and billing. Typical site of service is an operating room within an acute care hospital or ambulatory surgery center. The service is added to the primary breast procedure (e.g., lumpectomy) and is commonly performed for localized disease in appropriately selected patients seeking single‑fraction IORT at time of surgery.
