ICD-10 Code H53.132 – Sudden visual loss, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.132 – Sudden visual loss, left eye
What it is
H53.132 identifies a sudden loss of vision affecting the left eye. Use it when the record documents abrupt visual decline without a more specific eye disorder code.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe sudden blurred vision, marked decrease in visual acuity, or near-complete loss of sight in the left eye.
When to use this code
Use this code when the clinician documents sudden visual loss limited to the left eye and does not name a more specific cause. It may fit emergency or outpatient evaluations when the symptom is the primary finding. Check documentation if the chart suggests retinal, optic nerve, or vascular disease.
Do not use for
Do not use it when the vision loss is bilateral, chronic, or already explained by a definitive diagnosis. Also avoid it if the record identifies a different eye, such as the right eye.
Coding tip
Code the laterality exactly as documented and look for an underlying diagnosis before assigning the symptom code.
