About H26.1

H26.1 is the ICD-10-CM diagnosis code for traumatic 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), H26.1 is specifically for traumatic cataract. Related codes cover infantile and juvenile cataract (H26.0), complicated cataract (H26.2), 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: H26.10 (cataract), H26.11 (opacities), H26.12 (cataract) and H26.13 (cataract).

Use an additional code (Chapter 20) to identify external cause.

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