About H26.2
H26.2 is the ICD-10-CM diagnosis code for complicated cataract. 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 (other cataract), H26.2 is specifically for complicated cataract. Related codes cover infantile and juvenile cataract (H26.0), traumatic cataract (H26.1), drug-induced cataract (H26.3), secondary cataract (H26.4), other specified cataract (H26.8) and unspecified cataract (H26.9).
To report this condition, pick the subcode that matches the documentation: H26.20 (cataract), H26.21 (neovascularization), H26.22 ((inflammatory)) and H26.23 ((subcapsular)).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
