What 51840 covers
A urologist or urogynecologist performs this operation through an abdominal approach to support the bladder neck or urethra. Common techniques include Burch colposuspension and Marshall-Marchetti-Krantz repair, used for stress urinary incontinence related to inadequate urethral support. The service is generally performed in an operating room, rather than as an office procedure.
Choose this code when the operative report documents the abdominal suspension technique and the work is not described as complicated; a complicated or secondary repair is distinguished by code 51841. Document the indication, surgical approach, and structures supported. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

51840 billing questions
When should 51841 be used instead?
Use 51841 when the abdominal suspension is documented as complicated, such as a secondary repair. The operative report should support that distinction.
How does 51840 differ from a sling operation?
51840 describes abdominal bladder-neck or urethral suspension, such as a Burch or Marshall-Marchetti-Krantz procedure. A sling operation uses a sling to support the urethra and is reported with the code that matches its approach.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What documentation supports reporting 51840?
Document the stress-incontinence indication, abdominal approach, suspension technique, and structures supported. The operative details should also establish whether the repair was complicated or secondary.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, while team-surgery payment is not permitted.
