How coders use this code
ICD-10-CM C77.9 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of secondary and unspecified malignant neoplasm of lymph node, unspecified. 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.
