What 53855 covers
A urologist places a stent through the urethra into the prostatic segment to help keep the passage open when prostate enlargement obstructs urine flow. The service is used for men with lower urinary tract obstruction related to benign prostatic enlargement; cystoscopic placement is typical. It differs from procedures that ablate or remove prostate tissue because the treatment is stent placement rather than tissue destruction.
Report the insertion when the stent is placed, and document the indication, the device and its location, and the placement procedure. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

53855 billing questions
How does this differ from prostate tissue treatment codes?
This code represents placement of a prostatic urethral stent to maintain an open channel. Codes such as 53850, 53852, and 53854 describe prostate tissue treatment methods instead.
What documentation supports the service?
Document the obstructive indication, the stent placed and its prostatic location, and the procedural details confirming insertion.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inapplicable because this is not a bilateral procedure.
Is same-day care included in the procedure?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
When is an assistant-at-surgery payable?
Only when medical necessity for the assistant is documented. Co-surgeons and team surgery are not permitted for this code.
