What 45505 covers
This service involves reaching a rectal defect through the anal canal and closing it directly. A colorectal or general surgeon may perform it for a localized rectal wall injury or defect that can be exposed and repaired from below, typically in an operating room. The operative approach distinguishes this service from repairs requiring perineal or abdominal access.
Select the code from the approach and work documented, not from the diagnosis alone. The operative report should identify the rectal defect, its location, the transanal access, and the repair performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one 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 code; co-surgeons and team surgery are not permitted.

45505 billing questions
How does this differ from 45500?
The approach is the key distinction: 45505 is for repair reached through the anal canal, while 45500 represents a perineal approach. The operative report should support the approach used.
When would an abdominal repair code be more appropriate?
Use the applicable abdominal exploration-and-repair code when the surgeon explores and repairs the rectum through an abdominal approach. Codes 45562 and 45563 are alternatives to consider for that operative circumstance.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50 for the rectal repair.
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. The global period is tied to this major surgery.
What documentation supports reporting 45505?
Document the rectal defect or injury, the transanal route used to reach it, and the repair performed. Those details distinguish this service from perineal or abdominal repair.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
