ICD-10 Code H36.8 – Other retinal disorders in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H36.8 – Other retinal disorders in diseases classified elsewhere
What it is
H36.8 identifies retinal disorders that are caused by another underlying disease, but do not have a more specific retinal code. Use it when the record links the retinal problem to a separate condition.
Clinical signs
Clinical features vary; refer to documentation. Retinal findings may include visual disturbance, abnormal fundus changes, or other eye findings attributed to a systemic or local disease.
When to use this code
Use this code when the clinician documents a retinal disorder secondary to another disease and no more specific retinal diagnosis is stated. Make sure the underlying condition is also documented and coded when required. If the chart does not clearly connect the retinal disorder to another disease, check documentation.
Do not use for
Do not use H36.8 for primary retinal diseases that have their own ICD-10-CM code. Do not use it when the retinal condition is unspecified or when the documentation does not support a disease-in-elsewhere relationship.
Coding tip
Code the underlying disease first when it is the cause and the record supports a causal link.
