Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note 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.

open wound of eyelid and periocular area S01.1
retained foreign body in eyelid H02.8
retained old foreign body in penetrating wound of orbit and eye ball H05.5 H44.6 H44.7

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

The appropriate 7th character is to be added to each code from category T15

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

A - initial encounter
D - subsequent encounter
S - sequela

About the T15 Code Range

A foreign object on the outside of an eye may be identified by where it is and which eye is affected.

Within T15, the first split identifies the eye part: the cornea (T15.0), conjunctival sac (T15.1), other or multiple parts (T15.8), or an unspecified part (T15.9). Each branch then separates the right eye, left eye, and unspecified eye. The seventh character distinguishes an initial encounter (A), subsequent encounter (D), or sequela, a later effect (S).
