Summary & Overview
CPT 0686T: Image-Guided Focused Ultrasound Ablation of Liver Tumor
CPT code 0686T denotes an image-guided focused ultrasound procedure used to ablate cancerous liver tissue. This code captures a minimally invasive, device-based intervention where therapeutic ultrasound energy is delivered under real-time imaging to destroy targeted hepatic tumors. The technique is relevant nationally as a noninvasive or minimally invasive alternative to thermal ablation and surgical resection for selected liver malignancies, with implications for outpatient procedural coding, device utilization, and payer coverage policies.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service (hospital outpatient and ambulatory surgical centers), common modifier usage where available, and how the code fits into procedural service lines. The publication highlights benchmark considerations for utilization and coding consistency, summarizes national policy and coverage themes affecting adoption, and outlines areas where payers commonly request supporting documentation. The content is organized to support coding staff, clinical administrators, and policy analysts seeking a clear, national-level briefing on the code’s purpose, typical clinical setting, and billing implications.

Billing Code Overview
CPT code 0686T describes an image-guided therapeutic procedure in which a provider uses a specialized device to deliver focused ultrasound energy into the body to ablate cancerous liver tissue. The procedure is performed with continuous imaging guidance to monitor targeting and treatment effect.
-
Service type: Image-guided focused ultrasound ablation of liver tumors
-
Typical site of service: Hospital outpatient department or ambulatory surgical center with advanced imaging capabilities
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old with a known primary hepatocellular carcinoma or a solitary metastatic liver lesion referred for percutaneous tumor ablation. The patient undergoes pre-procedure evaluation including cross-sectional imaging (contrast-enhanced CT or MRI), laboratory testing (liver function, coagulation profile), and anesthesia assessment. On the day of the procedure the patient is positioned in an interventional radiology suite or hybrid operating room under moderate sedation, monitored anesthesia care, or general anesthesia depending on complexity and comorbidities. The interventional radiologist uses image guidance (ultrasound and/or CT) to place a specialized high‑intensity focused ultrasound device or applicator into or adjacent to the tumor. Ultrasound energy is delivered to thermally ablate the targeted liver tissue while real‑time imaging confirms applicator position and assesses ablation margins. Post‑procedure, immediate imaging documents ablation extent and checks for complications; the patient is recovered in a post‑anesthesia care unit and receives follow‑up imaging and oncology clinic coordination for ongoing cancer management.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, or intensity substantially exceeds typical for this ablation. |
52 | Reduced services | Use when the ablation is partially reduced or not completed. |
53 | Discontinued procedure | Use when the ablation is started but terminated due to extenuating circumstances. |
62 | Two surgeons | Use when two surgeons/physicians of different specialties share responsibility for the procedure. |
66 | Surgical team | Use when a surgical team performs the ablation requiring multiple physicians with defined roles. |
73 | Discontinued outpatient hospital/ASC procedure before anesthesia | Use when the procedure is discontinued prior to anesthesia administration. |
74 | Discontinued outpatient hospital/ASC procedure after anesthesia | Use when discontinued after anesthesia but before intended ablation. |
78 | Unplanned return to OR for related procedure during postoperative period | Use if unplanned reoperation for complication occurs related to the ablation. |
80 | Assistant surgeon present | Use for a qualified assistant surgeon during the ablation. |
81 | Minimum assistant surgeon | Use when a minimal assistance role is documented. |
82 | Assistant not available in facility | Use when a qualified resident or other approved assistant performs the assistant role. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when services are performed by an advanced practice clinician. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Use when the anesthesiologist directs concurrent anesthetics for this procedure. |
