What 52001 covers

A urologist passes a cystoscope through the urethra into the bladder, then irrigates and evacuates multiple clots obstructing bladder drainage. The procedure is commonly performed in a hospital or other procedural setting for gross hematuria with clot retention, such as when clots prevent adequate emptying or catheter drainage. The code describes endoscopic clot removal, not simple catheter irrigation alone.

Report the service for the cystoscopic treatment of multiple obstructing clots; document the obstruction, endoscopic irrigation and evacuation, and clinical reason for intervention. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery 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.

52001 billing questions

When is 52001 more appropriate than diagnostic cystoscopy?

Use 52001 when cystoscopy includes irrigation and evacuation of multiple obstructing clots. A diagnostic examination without that clot treatment is a different service.

Can bladder irrigation by catheter be reported instead?

Simple irrigation through a catheter is distinct from cystoscopic evacuation of multiple obstructing clots. Select the service that matches the documented method and work performed.

Should 52001 be reported once for each clot?

No. The code represents the cystoscopic clot-evacuation procedure, not a separate unit for every clot removed.

How are related endoscopies priced when performed together?

CMS endoscopy-family pricing applies when related endoscopies are performed together. Document each distinct procedure performed during the session.

Can modifier 50 or an assistant-at-surgery claim be used?

No. Modifier 50 is inappropriate for this code, and Medicare does not pay an assistant at surgery for it.

Are co-surgeons or team surgery allowed?

CMS does not permit co-surgeons or team surgery for this service.

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.
