What 51101 covers

This service drains the bladder through a suprapubic approach using a trocar or intracatheter. It is typically performed by a urologist or another physician when a patient with urinary retention needs bladder decompression and urethral access is unsuccessful or unsuitable. It may be performed in an office or facility setting. The service represents drainage, not placement of a suprapubic catheter for ongoing drainage.

Report 51101 when the documented technique uses a trocar or intracatheter; needle aspiration is described by 51100, while suprapubic catheter placement is 51102. Documentation should identify the indication, suprapubic approach, and drainage technique. The 0-day global period includes same-day preoperative and postoperative care. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

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.
