H35.8Other specified retinal disorders

H35.8 is the ICD-10-CM diagnosis code for other specified retinal disorders. It belongs to category H35 (other retinal disorders), 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 3 subcodes must be used instead.

Within H35, choose H35.8 (Other specified retinal disorders) only when documentation doesn't support a more specific option: background retinopathy and retinal vascular changes (H35.0), retinopathy of prematurity (H35.1), other non-diabetic proliferative retinopathy (H35.2), degeneration of macula and posterior pole (H35.3), peripheral retinal degeneration (H35.4), hereditary retinal dystrophy (H35.5), retinal hemorrhage (H35.6), separation of retinal layers (H35.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: H35.81 (edema), H35.82 (ischemia) and H35.89 (disorders).

The conditions in its Excludes2 note aren't part of H35.8, but may be coded alongside it if the patient has both: retinal hemorrhage (H35.6-).

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