How coders use this code
ICD-10-CM R85.616 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of satisfactory anal smear but lacking transformation zone. 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.
