ICD-10 Code H35.82 – Retinal Ischemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.82 – Retinal ischemia
What it is
H35.82 identifies retinal ischemia, a condition where the retina does not receive enough blood flow. This can impair retinal function and may threaten vision if the underlying cause is not addressed.
Clinical signs
Findings may include sudden or partial vision loss, blurred vision, or visual field defects. Clinical features vary; refer to documentation and ophthalmic examination results.
When to use this code
Use this code when the provider documents retinal ischemia as the diagnosis, including ischemic retinal changes confirmed on eye examination or imaging. It may also apply when the record clearly states retinal hypoperfusion affecting the retina. Do not infer it from nonspecific visual complaints alone.
Do not use for
Do not use H35.82 for general visual disturbance, retinal hemorrhage without ischemia, or other retinal disorders that are not documented as ischemic. Check documentation if the record only suggests vascular eye disease.
Coding tip
Assign H35.82 only when the note explicitly links the retinal finding to ischemia or inadequate retinal blood supply.
