How coders use this code
ICD-10-CM C20 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of malignant neoplasm of rectum. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
