Hi! This patient is status post left PCN placement and has a left ureteral stone and left ureteral stricture. At first I thought this would be 50080 and possibly 50575, but need some help. The provider states "proceedure performed" is a left renal endoscopy with left ureteroscpy with holium laser lithotripsy, Dilation of left ureteral stricture and placement of left ureteral stent. Please see note below. Thanks!
