What 51800 covers
A urologist uses this code for reconstructive surgery at the bladder neck and adjoining urethral outlet, which may include removing a wedge of bladder-neck tissue. The procedure is performed in an operating room to correct an outlet abnormality requiring reconstruction, rather than to suspend the bladder neck for support or simply close a bladder wound.
Select the code from the operative report’s description of the reconstructed anatomy and technique. Documentation should identify the indication, the bladder-neck and urethral work performed, and any wedge resection. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures 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 not appropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

- 51841Bladder suspensionComplicated repair

- 51860Bladder repairSimple wound suture
- 51860 is for repair of a bladder wound. It is not the same as reconstructing the bladder neck and adjoining urethral outlet.
51800 billing questions
How is this different from bladder-neck suspension?
This code describes reconstruction of the bladder-neck and adjoining urethral outlet. A suspension code is considered when the operative objective is to support the bladder neck or urethra, such as for stress urinary incontinence.
What documentation supports reporting this code?
The operative report should describe the outlet abnormality, the anatomy reconstructed, and the surgical steps, including whether a bladder-neck wedge was removed. The documented work should establish reconstruction rather than suspension or wound closure.
Are related postoperative visits included?
Yes. Medicare’s 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used?
No. The procedure is not treated as bilateral for payment adjustment, and modifier 50 is not appropriate.
How are other procedures in the same session paid?
When 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?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
