ICD-10-CM Excludes2 Notes ICD-10-CM
An Excludes2 note means "NOT INCLUDED HERE": the excluded condition is not part of this code, but a patient may have both, so both codes may be reported. The FY 2027 Tabular List has 2,529 Excludes2 Notes; 2,493 of them name other codes, with 2,799 references to 1,779 distinct codes, categories and ranges. Pick a chapter below to see every note in it, by the code that carries the note or by the code it names.
A type 2 Excludes note represents "Not included here". It indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
Excludes2 Notes by Chapter 22 chapters
“References to its codes” counts notes anywhere in the Tabular List that name a code in the chapter; “references in its notes” counts the codes named by notes printed in the chapter. Each chapter page shows both lists.
Questions About Excludes2 Notes
What does an Excludes2 note mean?
An Excludes2 note means “Not included here”: the excluded condition is not part of the condition represented by the code, but a patient may have both conditions at the same time (Section I.A.12.b). The FY 2027 Tabular List has 2,529 of them; 2,493 name other codes, with 2,799 references to 1,779 distinct codes, categories and ranges.
Can both codes be reported when there is an Excludes2 note?
Yes. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate: that is, when the patient has both conditions and both are documented.
What is the difference between Excludes1 and Excludes2?
Excludes1 means "not coded here": the two codes are never reported together, because the conditions cannot occur together. Excludes2 means "not included here": the excluded condition is not part of this code, but the patient may have both, so both codes may be reported (Section I.A.12).
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.
