How coders use this code
ICD-10-CM N80.549 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of endometriosis of the appendix, unspecified depth. 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.
