ICD-10 Code H36.819 – Nonproliferative sickle-cell retinopathy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H36.819 – Nonproliferative sickle-cell retinopathy, unspecified eye
What it is
This code identifies sickle-cell retinopathy that has not progressed to proliferative disease and affects an unspecified eye. Use it when the record confirms retinal involvement from sickle cell disease but does not name the right or left eye.
Clinical signs
Findings may include retinal vascular changes, peripheral ischemia, or small retinal hemorrhages. Clinical features vary; refer to documentation for the specific eye findings and whether the retinopathy is clearly nonproliferative.
When to use this code
Use H36.819 when the provider documents nonproliferative sickle-cell retinopathy and does not specify laterality. It also fits follow-up visits where the diagnosis is confirmed, but the note lacks a right-eye or left-eye designation. If the chart only says sickle-cell eye disease, check documentation before assigning this code.
Do not use for
Do not use this code for proliferative sickle-cell retinopathy or for unrelated retinal disorders. If the eye laterality is documented, choose the more specific code instead.
Coding tip
Always verify both disease stage and laterality in the ophthalmology note before coding.
