Summary & Overview
CPT 55873: Ultrasound-Guided Prostate Cryoablation
CPT code 55873 represents ultrasound-guided prostate cryoablation, a minimally invasive procedure that destroys cancerous prostate tissue by rapid freezing. Nationally, this code is important for tracking use of targeted prostate cancer treatments offered in outpatient surgical settings and for aligning clinical documentation with payer coverage and coding policies. Key payers in the national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn what the code represents clinically, where the service is typically provided, and the policy and billing context that commonly surrounds this procedure. The publication outlines typical sites of service, common billing considerations, and which payers are most relevant for coverage and claims adjudication. It also highlights benchmarks and policy updates where available and notes when data elements are not provided. This summary is intended for coding professionals, billing managers, and policy analysts seeking a concise reference on CPT code 55873 and its role in prostate cancer care pathways.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with clinically localized prostate cancer undergoes cryoablation of the prostate under transrectal ultrasound guidance as definitive or salvage therapy. He presents preoperatively after diagnosis by prostate biopsy (e.g., elevated PSA and confirmatory biopsy showing adenocarcinoma). The procedure is scheduled in an outpatient ambulatory surgery center or hospital operating room under monitored anesthesia care or general anesthesia. Intraoperative workflow includes ultrasound localization of the prostate, placement of cryoprobes under image guidance, controlled freeze-thaw cycles to ablate cancerous tissue, temperature monitoring, and urethral warming catheter placement to protect the urinary sphincter. Postprocedure recovery involves short observation for urinary retention, bleeding, or pain, catheter management, and discharge instructions with follow-up for PSA monitoring and urology clinic assessment.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When billing only the physician’s professional work separate from facility technical component (rare for this procedure). |
50 | Bilateral procedure | When cryoablation is documented and performed on both lobes of the prostate and payer requires bilateral modifier reporting. |
