ICD-10 Code H53.123 – Transient Visual Loss, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.123 – Transient visual loss, bilateral
What it is
This code identifies a temporary loss of vision affecting both eyes. The episode resolves, but the cause may still need evaluation.
Clinical signs
Patients may report sudden dimming, blackout, or brief inability to see in both eyes. Clinical features vary; refer to documentation.
When to use this code
Use H53.123 when the record clearly documents transient visual loss in both eyes, and no more specific diagnosis is established. It may fit brief, self-limited episodes described as bilateral vision loss or bilateral visual blackout. Check documentation if the note only mentions blurred vision or an unspecified visual complaint.
Do not use for
Do not use this code for persistent vision loss, unilateral episodes, or diagnoses that specify a different cause. If the chart documents a confirmed underlying disorder, code that condition instead.
Coding tip
Confirm that the provider documented both the transient nature and bilateral involvement before assigning H53.123.
