About H40.15
H40.15 is the ICD-10-CM diagnosis code for residual stage of open-angle glaucoma. 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 4 subcodes must be used instead.
Within H40.1 (open-angle glaucoma), H40.15 is specifically for residual stage of open-angle glaucoma. Related codes cover unspecified open-angle glaucoma (H40.10), primary open-angle glaucoma (H40.11), Low-tension glaucoma (H40.12), pigmentary glaucoma (H40.13) and capsular glaucoma with pseudoexfoliation of lens (H40.14).
To report this condition, pick the subcode that matches the documentation: H40.151 (right eye), H40.152 (left eye), H40.153 (bilateral) and H40.159 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
