H35.0Background retinopathy and retinal vascular changes

H35.0 is the ICD-10-CM diagnosis code for background retinopathy and retinal vascular changes. 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 9 subcodes must be used instead.

Within H35 (other retinal disorders), H35.0 is specifically for background retinopathy and retinal vascular changes. Related codes cover 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), other specified retinal disorders (H35.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: H35.00 (retinopathy), H35.01 (appearance), H35.02 (retinopathy), H35.03 (retinopathy), H35.04 (unspecified), H35.05 (unspecified), H35.06 (vasculitis), H35.07 (telangiectasis) and 1 more.

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