ICD-10 Code H35.89 – Other specified retinal disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.89 – Other specified retinal disorders
What it is
H35.89 is used for retinal disorders that do not fit a more specific ICD-10-CM retinal diagnosis. It signals an eye condition involving the retina, but the documentation names a distinct retinal problem not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Retinal disorders may be identified on funduscopic exam, imaging, or specialist evaluation, with findings such as retinal abnormalities, visual disturbance, or other documented retinal changes.
When to use this code
Use H35.89 when the provider documents a specific retinal disorder that lacks a dedicated ICD-10-CM code. It is appropriate when the record clearly identifies a retinal condition, but a more exact code is unavailable or not supported by the documentation. Confirm laterality and specificity if the note provides them.
Do not use for
Do not use this code for common retinal diagnoses that have their own ICD-10-CM codes, such as diabetic retinopathy or retinal detachment. If the documentation is vague or incomplete, check documentation rather than defaulting to H35.89.
Coding tip
Before assigning H35.89, verify that no more specific retinal code matches the documented condition.
