ICD-10 Code H35.021 – Exudative retinopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.021 – Exudative retinopathy, right eye
What it is
H35.021 identifies exudative retinopathy in the right eye. Use it when documentation specifies retinal exudation or a related exudative retinal disorder limited to the right eye.
Clinical signs
Findings may include retinal exudates, retinal vascular leakage, and visual disturbance. Clinical features vary; refer to documentation for the exact retinal description and laterality.
When to use this code
Use this code when the provider documents exudative retinopathy in the right eye, or an equivalent diagnosis clearly tied to that eye. It is appropriate when the record supports a unilateral right-eye condition and does not identify a more specific retinal disorder.
If the note only mentions retinal exudation without laterality, check documentation before coding. You should also confirm whether another retinal diagnosis better describes the encounter.
Do not use for
Do not use H35.021 for left-eye or bilateral disease, or when the record does not specify the right eye. Check documentation if the condition is better classified under another retinal diagnosis.
Coding tip
Verify laterality in the ophthalmology note before assigning H35.021.
