About 50845: Appendix-based catheterizable bladder channel
Creation of an appendix-based channel from the bladder to the abdominal wall, typically allowing a patient with difficult urethral access to catheterize and empty the bladder.
The surgeon uses the appendix to form a channel between the bladder and an abdominal opening that can be catheterized to drain urine. Urologists, including pediatric urologists, commonly perform this reconstruction for patients with neurogenic bladder or congenital urinary tract conditions who need a reliable catheterization route but cannot readily catheterize through the urethra. The procedure is performed in an operating room and may be part of a broader urinary reconstruction.
Report 50845 when the operative work creates this appendiceal channel; document the channel’s construction and its connection to the bladder and abdominal wall. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. If another separately reportable procedure is performed in the same 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 anatomy. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

50845 billing questions
How is 50845 different from a continent urinary diversion?
50845 describes a catheterizable channel made using the appendix to connect the bladder with an abdominal opening. A bowel-based continent diversion involves a different reconstruction and should be selected according to the anatomy and work documented.
Is bladder augmentation included in 50845?
The code describes creation of the appendiceal catheterization channel, not bladder enlargement. If augmentation is also performed, document that distinct work and determine separate reporting under the applicable coding edits.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
