When your urologist fragments more than one stone located in two different locations within the urinary tract during one operative session, the proper coding might leave you scratching your head: Can you ever report both procedures? If you can, how do you sequence the codes? Tackle these tough questions by reviewing a sample scenario.

Your urologist performs a ureteroscopic laser lithotripsy of a left ureteral stone and lithotripsy of a bladder stone. How should you code these procedure performed during one operative session?

Separately Report Procedures Based on Anatomy

Depending on where the stones are in the urinary tract, you may be able to separately report and be paid for multiple fragmentation procedures during the same session. For a ureteroscopic fragmentation of a ureteral or renal pelvic stone your urologist performs, you’ll report 52353 (Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with lithotripsy [ureteral catheterization is included]). Remember that 52353 applies to “any type of fragmentation, whether you use a Holmium laser, a Candela laser, a mechanical lithotripsy, or an ultrasonic lithotripter,” says Michael A. Ferragamo, MD, FACS, clinical assistant professor of urology at the State University of New York at Stony Brook. If your urologist also fragments a bladder calculus during the same session, your coding will then depend on the different and separate anatomical location of the stones. Therefore, in the sample scenario, you can separately report those procedures. “We are dealing with two separate portions or parts of the urinary tract – a ureteral stone and a bladder stone,” Ferragamo explains.

According to the Correct Coding Initiative (CCI), codes 52317 (Litholapaxy: crushing or fragmentation of calculus by any means in bladder and removal of fragments; simple or small [less than 2.5 cm]) and 52318 (…complicated or large [over 2.5 cm]) are bundled with 52353. Because both bundles have a...
