About H26.3

H26.3 is the ICD-10-CM diagnosis code for drug-induced 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), H26.3 is specifically for drug-induced cataract. Related codes cover infantile and juvenile cataract (H26.0), traumatic cataract (H26.1), complicated cataract (H26.2), 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: H26.30 (unspecified eye), H26.31 (right eye), H26.32 (left eye) and H26.33 (bilateral).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
