Choosing Between 52317 and 52318

Question: The urologist performed cystoscopy with bladder irrigation and urethral placement of cyberwand for cystolitholapaxy. How should we code this procedure?

Answer: The correct code choice is based on the size of the stone the urologist treated. Check for the stone’s size in the operative report, and then choose either 52317 (Litholapaxy: crushing or fragmentation of calculus by any means in bladder and removal of fragments; simple or small [less than 2.5 cm]) or 52318 (… complicated or large [over 2.5 cm]). For the fragmentation of multiple bladder stones of any size choose 52318.
