Type 2 Excludes
A type 2 excludes note represents "Not included here".

When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the H00–H05 Code Range
These conditions affect the eyelids, the tear gland and passages, or the orbit, the space around the eye.
The eyelid categories separate hordeolum and chalazion in H00, other inflammation in H01, and other disorders in H02. The other eyelid disorders include conditions affecting eyelid function and degenerative conditions.
H04 separates tear gland disorders from tear passage disorders, including acute or chronic inflammation and narrowing. H05 groups orbit disorders by condition, including acute or chronic inflammation, deformity, and a retained foreign body after a penetrating wound.
