Summary & Overview
CPT 0970T: Percutaneous Laser Ablation of Benign Breast Tumor
CPT code 0970T represents percutaneous laser ablation of benign breast tumors, such as fibroadenomas, using laser energy with image guidance. This minimally invasive, tissue-destructive procedure offers an alternative to surgical excision for selected patients and has implications for outpatient surgical practice patterns, device utilization, and payer coverage policies nationally. The code captures a specific, technology-driven procedure that can affect site-of-service decisions and resource use for breast lesion management.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical settings where the service is delivered, and the common modifiers associated with this code. The publication summarizes billing and coding considerations, benchmarks for utilization where available, and policy and coverage themes that influence access and reimbursement for image-guided breast tumor ablation.
This analysis helps clinicians, billing professionals, and policy stakeholders understand the procedural definition, typical use cases, and payer landscape relevant to CPT code 0970T. Data not available in the input are clearly noted where applicable.
Billing Code Overview
CPT code 0970T describes percutaneous laser ablation of a benign breast tumor (for example, a fibroadenoma). The procedure uses laser energy to destroy the tumor through a skin puncture, and providers may use imaging guidance (such as ultrasound or other imaging) to visualize and target the lesion.
Service type: Image-guided percutaneous tumor ablation
Typical site of service: Ambulatory surgical center or hospital outpatient department, and may also be performed in specialized outpatient imaging suites that support percutaneous, image-guided procedures.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult woman presenting with a palpable, well-circumscribed, benign breast mass identified on clinical exam and confirmed by imaging (diagnostic mammography and targeted breast ultrasound). The lesion is commonly a fibroadenoma measuring up to 3 cm, asymptomatic or causing focal discomfort or cosmetic concern. After imaging characterization and, when indicated, percutaneous core needle biopsy confirming benign histology, the patient is evaluated for minimally invasive treatment. The provider—most often an interventional radiologist, breast surgeon, or breast-specialist surgical oncologist—performs percutaneous laser ablation using local anesthesia in an outpatient setting with ultrasound or stereotactic guidance to target the lesion. Procedural workflow includes pre-procedure localization and imaging review, sterile prep, percutaneous needle insertion under image guidance, placement of laser fiber into the tumor, controlled application of laser energy to ablate the lesion, intraprocedural imaging to confirm adequate treatment margin, removal of the fiber, hemostasis, and short post-procedure observation before discharge. Typical site of service is an ambulatory surgical center or hospital outpatient department. Procedure documentation includes indication, lesion size and location, imaging guidance modality, anesthesia type, energy settings and duration, number of fibers used, immediate imaging assessment, complications if any, and post-procedure instructions and follow-up imaging plan.
Coding Specifications

53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances or those that threaten the patient. |
54 | Surgical care only | Use when reporting only the portion of care involving the surgical procedure (other providers report pre/post care). |
55 | Postoperative management only | Use when reporting only postoperative care separate from the operating physician. |
56 | Preoperative evaluation only | Use when reporting only the preoperative evaluation when another surgeon performs the procedure. |
62 | Two surgeons | Use when two surgeons with different specialties work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team | Use when multiple surgeons function as a surgical team for a complex case requiring multiple skilled surgeons. |
78 | Unplanned return to the operating room by same physician following initial procedure | Use when a return to the OR for related care occurs during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon provides intraoperative assistance. |
81 | Minimum assistant surgeon | Use when a minimum-level assistant surgeon assists. |
82 | Assistant surgeon (when a qualified resident is unavailable) | Use when assistance is provided because a qualified resident is not available. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice clinician acts as an assistant during the procedure. |
