What 51700 covers
This service involves flushing the bladder with fluid or instilling fluid through a urinary catheter. A urologist or another clinician may perform it in an office or facility to clear blood clots or debris, or to address a catheter that is not draining because of material in the bladder. The work is irrigation itself, rather than catheter placement alone.
Document the reason for irrigation, the method or catheter used, and the service performed, including the material flushed or instilled and the patient’s response when relevant. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When it is performed in the same session as other procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

51700 billing questions
How is irrigation different from bladder catheter insertion?
Irrigation describes flushing or instilling fluid in the bladder; catheter insertion codes describe placing a catheter. Choose based on the service documented, not simply on the presence of a catheter.
Can catheter insertion be reported with irrigation?
The irrigation service does not by itself describe catheter insertion. If both services were performed, document each distinctly and verify that reporting both is supported by applicable coding edits.
Is modifier 50 appropriate for irrigation of both sides?
No. The bladder is not a paired structure for this service, and CMS identifies bilateral adjustment as inappropriate.
What same-session payment rule applies?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures performed in the same session are paid at 50%.
Are assistant, co-surgeon, or team-surgery modifiers payable?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
What documentation supports the service?
Record the clinical reason for irrigation, the catheter or method used, what was flushed or instilled, and the patient’s response when relevant.
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.
