Excludes2 Notes in Chapter 7: Diseases of the eye and adnexa 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. In Chapter 7 (H00-H59), notes printed in the chapter name other codes 69 times, and Excludes2 Notes anywhere in the Tabular List name the chapter’s codes 81 times, covering 52 distinct codes, categories and ranges. Switch views to read the list either way.

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.
