ICD-10 Code H53.129 – Transient Visual Loss, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.129 – Transient visual loss, unspecified eye
What it is
This code identifies a temporary loss of vision affecting an unspecified eye. It is used when the chart documents transient visual loss but does not specify the eye or a more precise cause.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe brief, reversible visual dimming, blackout, or partial loss that resolves spontaneously and leaves no permanent deficit.
When to use this code
Use this code when the provider documents transient visual loss and does not identify the right or left eye. It also fits cases where the episode is recorded without a confirmed underlying diagnosis. If the record specifies a cause, laterality, or a different visual disorder, code that information instead.
Do not use for
Do not use this code for permanent vision loss, blurred vision alone, or documented visual symptoms with a known alternate diagnosis. Check documentation.
Coding tip
Confirm whether the episode is truly transient and whether laterality is documented before assigning H53.129.
