ICD-10 Code H53.12 – Transient Visual Loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.12 – Transient visual loss
What it is
H53.12 identifies a temporary loss or reduction of vision that resolves. You use it when the record documents transient visual loss without a more specific underlying diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe sudden, brief vision loss in one or both eyes, with full or near-full recovery afterward.
When to use this code
Use this code when the clinician documents transient visual loss as the assessed problem and no more specific cause is established. It may appear in emergency, neurology, or ophthalmology records when symptoms have resolved by the time of evaluation.
If the chart identifies an underlying disorder, such as vascular, neurologic, or ocular disease, code that condition instead or in addition, as supported by documentation. Check documentation for laterality, duration, and whether the episode was monocular or binocular.
Do not use for
Do not use H53.12 for chronic visual impairment, unspecified blurred vision, or a confirmed diagnosis with a different code. Do not use it when the note only says “vision changes”; check documentation.
Coding tip
Code the symptom only when transient visual loss is explicitly documented and no more specific etiology is confirmed.
