H35.4Peripheral retinal degeneration

H35.4 is the ICD-10-CM diagnosis code for peripheral retinal degeneration. 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 7 subcodes must be used instead.

Within H35 (other retinal disorders), H35.4 is specifically for peripheral retinal degeneration. Related codes cover 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), hereditary retinal dystrophy (H35.5), retinal hemorrhage (H35.6), separation of retinal layers (H35.7), other specified retinal disorders (H35.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: H35.40 (degeneration), H35.41 (retina), H35.42 (retina), H35.43 (retina), H35.44 (retina), H35.45 (degeneration) and H35.46 (degeneration).

Don't report H35.4 together with the conditions in its Excludes1 note: hereditary retinal degeneration (dystrophy) (H35.5-).

The conditions in its Excludes2 note aren't part of H35.4, but may be coded alongside it if the patient has both: peripheral retinal degeneration with retinal break (H33.3-).

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