About H26.23
H26.23 is the ICD-10-CM diagnosis code for glaucomatous flecks (subcapsular). It belongs to category H26 (other cataract), block H25-H28 (disorders of lens) 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 H26.2 (complicated cataract), H26.23 is specifically for glaucomatous flecks (subcapsular). Related codes cover unspecified complicated cataract (H26.20), cataract with neovascularization (H26.21) and cataract secondary to ocular disorders (degenerative) (inflammatory) (H26.22).
To report this condition, pick the subcode that matches the documentation: H26.231 (right eye), H26.232 (left eye), H26.233 (bilateral) and H26.239 (unspecified eye).
Code first: underlying glaucoma (H40-H42).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
