Summary & Overview
CPT 0655T: Transperineal Laser Ablation of Malignant Prostate Tissue
CPT code 0655T denotes a transperineal, image-guided laser ablation procedure for malignant prostate tissue that incorporates enhanced imaging such as MR–fused ultrasound. This emerging, incision-sparing intervention matters nationally as it reflects growing use of targeted, image-guided focal therapies in prostate cancer management and potential impacts on surgical volume, imaging utilization, and ambulatory procedure adoption. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of what CPT code 0655T covers, the clinical context of transperineal laser ablation with MR–fused imaging, and typical sites where the procedure is performed. The publication summarizes expected billing considerations and common modifiers (listed separately), outlines payer coverage presence, and highlights benchmarks and policy topics relevant to adoption and reimbursement. The content is intended to help stakeholders understand the code’s scope, clinical role in prostate cancer care, and where to look for payer guidance and utilization trends. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0655T describes a minimally invasive ablative procedure in which the provider uses a laser to destroy malignant prostate tissue via a transperineal approach with transrectal imaging guidance. The service includes the use of enhanced ultrasound imaging, such as MR–fused images that combine a magnetic resonance image of the prostate with real-time ultrasound to guide ablation.

Service type: Image-guided transperineal prostate laser ablation with MR–fused ultrasound guidance

Typical site of service: Ambulatory surgical center or hospital outpatient setting
Clinical & Coding Specifications
Clinical Context
A typical patient is a man aged 60–80 years with biopsy-proven localized prostate cancer who is a candidate for focal or partial gland ablation. The patient often presents after rising prostate-specific antigen (PSA) levels, suspicious multiparametric MRI findings, and targeted biopsy confirming clinically significant cancer (e.g., Grade Group 1–3 localized to discrete prostate regions). The clinical workflow includes preprocedure evaluation (history, physical, laboratory testing including PSA, imaging review with MRI and transrectal ultrasound correlation), informed consent discussing transperineal ablative approach and alternatives, perioperative planning (antibiotic prophylaxis, anticoagulation management), and selection of fusion imaging strategy to integrate prior MRI with real-time transrectal ultrasound.
On the day of service the patient is positioned for a transperineal approach under general or regional anesthesia in an ambulatory surgery center or hospital outpatient setting. The proceduralist obtains MR–fused ultrasound guidance to localize the tumor, inserts transperineal needles or laser fiber(s), and performs laser ablation of malignant prostate tissue. Postprocedure monitoring includes immediate recovery observation for bleeding, urinary retention, infection, and pain management, with discharge instructions and planned follow-up PSA and imaging to assess treatment response.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for 0655T (document rationale for increased complexity). |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for a procedure that is usually performed with local or monitored anesthesia care. |
51 | Multiple procedures | Use when 0655T is billed on the same date as other unrelated surgical procedures by the same provider. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned but still performed. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances or patient safety. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team | Use when a surgical team performs the procedure and billing reflects team services. |
78 | Unplanned return to OR by same surgeon | Use when the patient returns to the operating room for a related procedure during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon participates in the procedure. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when an eligible nonphysician practitioner is billing under their own NPI for a portion of the procedure (payer dependent). |
| Taxonomy Code | Specialty | Notes |

2084P0705X | Urology | Urologists commonly perform prostate ablation procedures. |
207RP1001X | Interventional Radiology | Interventional radiologists may perform image-guided prostate ablations using transperineal approach and fusion imaging. |
363L00000X | Radiation Oncology | Radiation oncologists may be involved in multidisciplinary planning and follow-up for prostate cancer ablation. |
