Summary & Overview
CPT 55709: Transperineal Ultrasound-Guided Prostate Biopsy
CPT code 55709 denotes a transperineal ultrasound-guided prostate biopsy in which the clinician collects cores from standard mapped sextants and any sonographically identified lesions. This procedure is a key diagnostic tool for detecting prostate cancer and guiding subsequent management decisions. Nationally, transperineal approaches have grown in relevance due to potential differences in infection risk and sampling patterns compared with transrectal techniques. Coverage and coding guidance for 55709 influences access to image-guided prostate biopsy across outpatient settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service delivery for 55709, a review of typical sites of service and operational considerations, and where available, payer coverage patterns and policy notes.

Clinical & Coding Specifications
Clinical Context
A 66-year-old male with an elevated prostate-specific antigen (PSA) and a suspicious region noted on transrectal ultrasound (TRUS) or prior MRI is scheduled for a transperineal ultrasound-guided prostate biopsy. The patient presents to an outpatient urology clinic or ambulatory surgical center on the day of the procedure after pre-procedure counseling and consent. In the pre-procedure area the nurse confirms allergies, reviews anticoagulation status, and ensures appropriate antibiotics have been given per local protocol. The urologist uses ultrasound to map the prostate and performs systematic sampling from standard sextant regions and targets any discrete lesions seen on ultrasound. Local anesthesia, sedation, or general anesthesia may be used depending on patient factors and facility protocols. Post-procedure, the patient is monitored briefly for bleeding or urinary retention, given post-biopsy instructions, and discharged with arrangements for pathology follow-up and results review.
