ICD-10 Code H36.821 – Proliferative sickle-cell retinopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H36.821 – Proliferative sickle-cell retinopathy, right eye
What it is
This code identifies proliferative sickle-cell retinopathy affecting the right eye. It means abnormal retinal blood vessel growth or related proliferative changes are documented in a patient with sickle-cell disease.
Clinical signs
Findings may include retinal neovascularization, vitreous hemorrhage, or peripheral retinal ischemia on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states proliferative sickle-cell retinopathy in the right eye. It is appropriate for ophthalmology assessments, retinal imaging reports, or specialist notes that specify laterality.
If the documentation mentions sickle-cell retinopathy without proliferative change or without eye laterality, check documentation before coding. You need support for both the proliferative nature and the right-eye designation.
Do not use for
Do not use this code for nonproliferative sickle-cell retinopathy, unspecified eye, or retinopathy from another cause. Check documentation if the laterality or diagnosis wording is incomplete.
Coding tip
Always confirm the note states both “proliferative” and “right eye” before assigning H36.821.
