About H40.119
H40.119 is the ICD-10-CM diagnosis code for primary open-angle glaucoma, unspecified eye. It belongs to category H40 (glaucoma), block H40-H42 (glaucoma) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.
Within H40.11, choose H40.119 (unspecified eye) only when documentation doesn't support a more specific option: right eye (H40.111), left eye (H40.112) and bilateral (H40.113).
Codes in this range require a 7th character: 0 for stage unspecified, 1 for mild stage, 2 for moderate stage, 3 for severe stage and 4 for indeterminate stage. Use placeholder "X" characters to fill any empty positions before the 7th character.
It was added in FY2017, effective October 1, 2016.
