Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 55877 covers

A urologist uses percutaneously placed electrodes to deliver electrical pulses that disrupt tumor-cell membranes in one or more prostate tumors. This irreversible electroporation approach is used for targeted treatment of prostate cancer and differs from techniques that destroy tissue by freezing or focused ultrasound. Imaging guidance is included when performed. The service is generally performed in a procedural or surgical setting.

Report one unit for the treatment of one or more tumors; document the percutaneous approach, irreversible electroporation method, treated tumor site or sites, and any imaging guidance. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
