CPT 55710 Transperineal MRI–US Fusion Reimbursement

CPT code 55710 represents a transperineal, ultrasound-guided prostate biopsy that performs systematic sextant sampling alongside MRI–ultrasound fusion targeting of suspicious lesions. This procedure is increasingly used in diagnostic pathways for men with elevated prostate-specific antigen (PSA) or suspicious imaging because it combines systematic coverage of standard prostate regions with focused sampling of MRI-identified targets, improving detection of clinically significant prostate cancer while reducing sampling error.

Key payers considered in this national overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on clinical context and service delivery, payer coverage patterns, billing and coding considerations, and related codes. The publication highlights benchmarks for utilization and reimbursement trends where available, summarizes relevant policy updates affecting imaging–fusion biopsy coverage, and outlines common billing scenarios and documentation elements necessary for claims adjudication.

This summary is intended to inform payers, providers, and revenue cycle teams about the clinical role of 55710, typical sites of service, and the kinds of analyses and benchmarks contained in the full publication. Data not available in the input is noted where applicable in the detailed sections.

Billing Code Overview

CPT code 55710 describes a transperineal ultrasound–guided prostate biopsy that includes systematic sampling of mapped sextant areas and MRI–ultrasound fusion targeting of a suspicious lesion. The procedure combines standard mapped biopsies with image-fusion technology to increase the likelihood of detecting clinically significant prostate cancer.

Service type: Image-guided diagnostic prostate biopsy combining systematic (sextant) sampling and MRI–ultrasound fusion–targeted sampling
Typical site of service: Outpatient urology clinic or ambulatory surgical center where ultrasound and MRI-fusion equipment are available

Clinical Context

A 64-year-old man with elevated prostate-specific antigen (PSA) and a suspicious region identified on multiparametric prostate MRI is scheduled for a transperineal ultrasound–guided prostate biopsy with MRI–ultrasound fusion targeting. The patient presents to an outpatient ambulatory surgical center after pre-procedure counseling and informed consent. Under monitored anesthesia care or light general anesthesia, the urologist or interventional radiologist performs a sterile transperineal approach using a transrectal ultrasound probe for imaging and an MRI–ultrasound fusion platform to overlay the suspicious lesion onto real-time ultrasound. Systematic sampling is performed from mapped sextant regions and additional targeted cores are obtained from the fused MRI lesion. Hemostasis is confirmed, local measures are applied, and the patient is recovered and discharged with post-biopsy instructions and arrangements for pathology results and follow-up.

`26`	Professional component	Use when billing is split and only the physician interpretation/procedure component is reported separately from technical services.
`TC`	Technical component

Taxonomy Code	Specialty	Notes
`208800000X`	Urology	Urologists commonly perform prostate biopsies, including transperineal MRI–fusion techniques.
`2084P0800X`	Diagnostic Radiology	Interventional radiologists may perform image-guided transperineal biopsies using fusion platforms.
`363L00000X`	Physician Assistant	PAs may assist in pre-procedure, intra-procedure support, and post-procedure care under supervision.
`207RR0500X`	Nurse Practitioner	NPs provide peri-procedural care, consent, and follow-up for biopsy patients.
`206E00000X`	Anesthesiology	Anesthesia providers deliver monitored anesthesia care or general anesthesia for patient comfort during the procedure.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`R97.2`	Elevated prostate specific antigen [PSA]	Common indication for targeted prostate biopsy when PSA is persistently elevated.
`N40.0`	Enlarged prostate without lower urinary tract symptoms	May be listed as a comorbidity; can coexist with indications for biopsy.
`N41.9`	Inflammatory disease of prostate, unspecified	Prostatitis can cause PSA elevation and may be considered in differential before biopsy.
`C61`	Malignant neoplasm of prostate	Primary diagnosis when biopsy confirms prostate cancer; biopsy is diagnostic.
`R92.8`	Other abnormal and inconclusive findings on diagnostic imaging of breast (used here analogously)	Data not typically used for prostate MRI; do not use this code for prostate—Data not available in the input.
`Z12.5`	Encounter for screening for malignant neoplasm of prostate	Used when biopsy is performed following abnormal screening or as part of screening protocols.
