Summary & Overview
CPT 0353T: Intraoperative OCT for Breast Margin Assessment
CPT code 0353T identifies an intraoperative optical coherence tomography (OCT) imaging procedure used to evaluate the surgical cavity following breast excision to determine if margins are clear of cancer cells. The code matters nationally as it supports immediate intraoperative decision-making that can reduce re-excision rates and influence operative time, resource use, and downstream costs in breast-conserving surgery. Adoption and coverage of this code affect hospitals, surgical oncologists, and imaging vendors deploying OCT technology.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of what the code represents clinically, how it is commonly applied in the operating room setting, and the major payer landscape influencing coverage and payment. The publication summarizes benchmarking metrics where available, highlights recent policy or coding updates impacting clinical adoption, and situates the procedure in operative workflow and quality-of-care discussions. Practical context includes expected service line (intraoperative diagnostic imaging) and typical site of service (operating room/procedure suite). Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 0353T describes an intraoperative imaging procedure using optical coherence tomography (OCT) to assess the surgical cavity after breast excision. The technology provides immediate, high-resolution visualization of tissue margins to detect residual cancer cells at the time of surgery.
-
Service type: Intraoperative diagnostic imaging
-
Typical site of service: Operating room or procedure suite during breast-conserving surgery

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old woman who presents for breast-conserving surgery (lumpectomy) after imaging and core biopsy confirmed invasive ductal carcinoma. Intraoperative optical coherence tomography (OCT) imaging using 0353T is performed by the operating surgeon or a trained intraoperative imaging specialist immediately after tumor excision. The imaging device scans the surgical cavity margins to identify residual cancer cells at the resection bed, providing real-time feedback on margin status. If OCT identifies suspicious areas, the surgeon performs additional targeted shave excisions and repeats imaging until margins are assessed as clear or the clinical team determines further resection is not feasible. Typical site of service is an ambulatory surgical center or hospital operating room during a breast-conserving procedure. Usual providers include breast surgical oncologists, general surgeons with breast specialization, and operating room staff supporting intraoperative imaging.
