ICD-10 Code H53.34 – Suppression of binocular vision (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.34 – Suppression of binocular vision
What it is
H53.34 identifies suppression of binocular vision, a condition where the brain reduces input from one eye to avoid double vision or visual conflict. It is an abnormal binocular vision finding, not a refractive error.
Clinical signs
Clinical features vary; refer to documentation. Commonly, one eye is ignored during binocular viewing, and patients may show reduced binocular fusion or a history of amblyopia, strabismus, or intermittent diplopia.
When to use this code
Use H53.34 when the provider documents suppression of binocular vision as the diagnosed finding. It may be appropriate in ophthalmology or orthoptic assessments when testing shows the patient is not using both eyes together normally. Do not assume it from strabismus alone; check documentation.
Do not use for
Do not use this code for simple decreased visual acuity, refractive error, or unspecified visual disturbance. If the record only mentions strabismus or amblyopia without suppression, code the documented condition instead.
Coding tip
Code H53.34 only when suppression is explicitly documented or clearly supported by the exam note.
