Hyperplastic versus Adenomatous Colon Polyp
Coding Clinic, Second Quarter 2015, page 14, advised to assign code K63.5, Polyp of colon, when the physician documents a hyperplastic colon polyp regardless of the location in the colon. Therefore, would a hyperplastic polyp at any colonic site (e.g., ascending, descending, sigmoid, etc.) be assigned code K63.5, Polyp of colon, even though the ICD-10-CM subcategorizes specific locations of neoplastic polyps? For example, a patient had a colonoscopy with removal of an ascending colon polyp. No additional information is available regarding histology. Would code D12.2, Benign neoplasm of ascending colon, or code K63.5, Polyp of colon, be reported? ...

Article Overview
This article reviews an ICD-10-CM coding question involving colon polyp documentation and how coding guidance addresses different polyp types and an unspecified pathology scenario. It is relevant for coders, CDI staff, auditors, and clinicians working with colonoscopy documentation, pathology reporting, and diagnosis assignment. The discussion centers on the coding implications of broad polyp terminology, location-specific neoplasm categories, and related official guidance.
Why This Topic Matters
Accurate diagnosis coding for colon polyps depends on how the finding is documented and whether pathology or histology is available. This article helps readers understand the scope of ICD-10-CM guidance that affects coding consistency for colonoscopy-related diagnoses.
