About H26.49

H26.49 is the ICD-10-CM diagnosis code for other secondary 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 H26.4, choose H26.49 (Other secondary cataract) only when documentation doesn't support a more specific option: unspecified secondary cataract (H26.40) and Soemmering's ring (H26.41).

To report this condition, pick the subcode that matches the documentation: H26.491 (right eye), H26.492 (left eye), H26.493 (bilateral) and H26.499 (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.
