About H35

H35 is the ICD-10-CM diagnosis code for other retinal disorders. It belongs to block H30-H36 (disorders of choroid and retina) 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H35.0 (changes), H35.1 (prematurity), H35.2 (retinopathy), H35.3 (pole), H35.4 (degeneration), H35.5 (dystrophy), H35.6 (hemorrhage), H35.7 (layers) and 2 more.

The conditions in its Excludes2 note aren't part of H35, but may be coded alongside it if the patient has both: diabetic retinal disorders (E08.311-E08.359, E09.311-E09.359, E10.311-E10.359, E11.311-E11.359, E13.311-E13.359).

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