I am new to coding and am having a dilemma--Recently, a doctor did a colonoscopy but could only reach half way through the decending colon. He removed the polyps he saw there. If he did not reach the splenic flexure to qualify for a complete colonoscopy, then should this be coded with a 52 modifier? Does the fact that he removed polyps make it a complete procedure even though he did not go far enough to qualify as complete? Any ideas?
