Question:
In a diagnostic colonoscopy, if the prep is incomplete and the scope cannot be advanced past the splenic flexure, do I report a diagnostic colonoscopy (45378) with a modifier?

Answer:
No. CPT says if the scope cannot advance past the splenic flexure, report a diagnostic sigmoidoscopy, code 45330.
