What 55873 covers

A urologist uses probes placed through the perineum to freeze prostate tissue, with ultrasound used to guide and monitor treatment. The procedure is commonly performed in a hospital or ambulatory surgery setting for localized prostate cancer, including selected cases treated after recurrence following radiation. The treatment may target the gland or a defined area, depending on the clinical plan.

Report the service when the documented procedure uses cryotherapy to ablate prostate tissue; the operative note should identify the indication, treatment extent, probe placement, and freezing process. Ultrasound guidance and monitoring are included in the service. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

55873 billing questions

How does this differ from prostate HIFU ablation?

This code is for cryotherapy, which destroys tissue by freezing. HIFU uses focused ultrasound energy and is reported with the code specific to that technique.

Can ultrasound guidance be billed separately?

Ultrasound guidance and monitoring are included in the cryoablation service. Do not separately report them for guidance or monitoring integral to this procedure.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Can modifier 50 or an assistant-at-surgery modifier be used?

Modifier 50 is inappropriate for this prostate procedure. Medicare does not pay an assistant at surgery for this service.

What should the operative note support?

Document the prostate condition treated, the extent of tissue targeted, probe placement, and the cryotherapy performed. The record should also support that the treatment used freezing rather than another ablation method.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
