Urology procedure
About 51100: Percutaneous bladder needle aspiration
Reports suprapubic needle aspiration of the bladder, commonly to obtain urine when urethral catheterization is unsuitable or cannot be performed.
A clinician punctures the bladder through the lower abdominal wall with a needle and aspirates its contents, commonly urine for a specimen when urethral catheterization is unsuitable or cannot be performed. Urologists and other physicians may perform the procedure in an office, emergency department, or hospital setting. The distinguishing feature is needle aspiration without placement of a suprapubic drainage catheter; a catheter or trocar approach belongs to a different code.
Report 51100 for the needle aspiration itself. Documentation should identify the percutaneous needle approach and the reason for the procedure, such as obtaining urine when urethral access is not suitable. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur 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. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

51100 billing questions
How is 51100 different from 51101?
51100 is needle aspiration without catheter placement. 51101 describes bladder drainage using a trocar or catheter approach.
Does 51100 include placement of a suprapubic catheter?
No. It covers needle aspiration; when a suprapubic catheter is inserted, consider 51102 instead.
Can 51100 be billed with a catheterization code?
A separate urethral catheterization should reflect a distinct service, not merely another way of describing the bladder access used for the aspiration. 51701 describes non-indwelling urethral catheterization, rather than percutaneous needle aspiration.
Should modifier 50 be appended?
No. The bladder procedure is not reported bilaterally, and the CMS bilateral adjustment does not apply.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure. If multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 51100. Co-surgeons and team surgery are not permitted.
