What 52310 covers

A urologist typically performs this brief endoscopic service in an office, ambulatory surgery center, or hospital setting. Using a cystoscope, the physician removes a foreign body, small calculus, or ureteral stent from the urethra or bladder. A common use is removal of a ureteral stent that has reached the bladder. The service is limited to simple removal; a complicated removal belongs to the related higher-level code.

Choose the code from the documented site and complexity, and record the item removed and the work performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing affects payment. The bilateral adjustment is inappropriate for this service. CMS does not pay an assistant at surgery, 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.

Use 52315 when the removal is documented as complicated. This code describes simple removal from the urethra or bladder.

Can this code be used to remove a ureteral stone?

This code covers removal from the urethra or bladder. For a ureteral calculus removed endoscopically, compare the procedure with 52320 or the applicable ureteroscopic stone-removal code.

Does removal of a ureteral stent qualify?

Yes, when the stent is removed from the urethra or bladder by cystoscopy. Document the stent removal and the work performed.

Can modifier 50 be reported?

CMS endoscopy family pricing applies when related endoscopies are performed together, affecting payment for the combined session.

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.
