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.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician’s interpretation of the OCT imaging separate from technical equipment charges. |
TC | Technical component | Use when billing only the technical component (imaging device, technologist) for intraoperative OCT. |
52 | Reduced services | Use when OCT was performed but limited in scope or incomplete relative to full procedure due to technical or clinical constraints. |
53 | Discontinued procedure | Use when OCT was started but discontinued for reasons such as intraoperative instability or equipment failure. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during the breast procedure and both report involvement in imaging-guided decisions. |
22 | Increased procedural services | Use when intraoperative complexity required substantially greater work due to difficult anatomy or extensive margin sampling. |
56 | Pre-operative care only | Use when the provider billed only for preoperative work related to planning OCT-guided surgery and did not perform intraoperative services. |
55 | Post-operative care only | Use when the provider billed only for postoperative care when another surgeon performed the intraoperative imaging-guided excision. |
52 | Reduced services | Use when OCT imaging was performed in a limited manner (duplicate entry omitted in final billing — see above). |
AS | Ambulatory surgical center facility | Use to indicate the service was performed in an ambulatory surgical center setting when required by payer rules. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207XS0104X | Surgical Oncology | Breast surgical oncologists who perform lumpectomy and intraoperative margin assessment. |
| 207P00000X | General Surgery | General surgeons with breast specialization who perform intraoperative imaging and re-excision. |
| 2080S0110X | Plastic and Reconstructive Surgery | Reconstructive surgeons who may be involved when oncoplastic techniques are combined with intraoperative margin assessment. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
C50.911 | Malignant neoplasm of unspecified site of right female breast | Common primary diagnosis indicating invasive breast cancer treated with lumpectomy and intraoperative margin assessment using OCT. |
C50.912 | Malignant neoplasm of unspecified site of left female breast | As above, for left-sided breast cancer where OCT is used intraoperatively to assess margins. |
D05.10 | Lobular carcinoma in situ of unspecified breast | High-risk lesion or in situ disease where precise margin assessment is relevant during breast-conserving surgery. |
D05.91 | Unspecified type of intraductal carcinoma in situ of breast | DCIS often requires careful margin assessment intraoperatively to reduce re-excision rates; OCT can assist. |
Z90.11 | Acquired absence of right breast and nipple | Relevant when assessing contralateral or reconstructive planning; may impact surgical approach though less commonly the indication for OCT. |
