ICD-10 Code H53.131 – Sudden visual loss, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.131 – Sudden visual loss, right eye
What it is
This code identifies a sudden decrease or loss of vision in the right eye. It describes the symptom, not the underlying cause, so you should code the diagnosed condition separately when known.
Clinical signs
Patients may report abrupt blurred vision, dimming, or complete loss of sight in the right eye. Clinical features vary; refer to documentation for associated findings such as pain, field loss, or neurologic symptoms.
When to use this code
Use H53.131 when the record documents sudden visual loss limited to the right eye and no more specific diagnosis is established at the encounter. It is appropriate for symptom-based coding while evaluation is ongoing. If the provider identifies a cause, code that condition instead of, or in addition to, this symptom.
Do not use for
Do not use this code for chronic, gradual, or bilateral vision loss. It is also not the best choice when the chart documents a specific ocular or neurologic disorder causing the symptom.
Coding tip
Check whether the provider documented laterality and a definitive cause before assigning this symptom code.
