Questions About Includes Notes

What does an Includes note mean in ICD-10-CM?

An Includes note appears immediately under a three-character category title to further define, or give examples of, the content of the category (Section I.A.10). It describes what the category covers; it does not add a code. The FY 2027 Tabular List has 1,023 of them; 38 name other codes, with 89 references to 82 distinct codes, categories and ranges.

Does an Includes note apply to every code in the category?

Yes. The note sits under the category heading, so it describes every subcategory and code beneath it. ICD List code pages repeat the category’s Includes note on each code under it, marked as inherited.

Official Sources & Methodology

Every note on these pages is loaded verbatim from the FY 2027 ICD-10-CM Tabular List. Code references inside the notes are matched against the FY 2027 code set, so every link opens a valid code; scope counts (“applies to N codes”) count the billable codes under the note’s chapter, block or category.

ICD List is not affiliated with CMS or NCHS. These pages are a coding reference; the Tabular List and the Official Guidelines remain the authority.
