I need help in regards to when 74420 should be used and when it shouldn't. Pt had cystoscopy , ureteroscopy w/laser lithotripsy and ureteral stent insertion. We billed 52356-50 and 74420-TC to the ins and the insurance denied 74420-TC. I am still unsure when to use 74420 over 52005. Any help would be greatly appreciated! Pam
