ICD-10 Code H53.2 – Diplopia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.2 – Diplopia
What it is
Diplopia means double vision, where you see two images of one object. Use this code when the chart documents binocular or monocular double vision without a more specific underlying diagnosis.
Clinical signs
Patients may report seeing side-by-side, overlapping, or vertical images. Clinical features vary; refer to documentation, and note whether the diplopia is constant, intermittent, binocular, or monocular.
When to use this code
Use H53.2 when the provider documents diplopia as the diagnosed problem or as a symptom being evaluated. It is appropriate when the record does not identify a more specific cause, such as cranial nerve palsy or strabismus.
Code the documented type when available, and follow the provider’s assessment if the double vision is linked to another confirmed condition. Check documentation if the cause is uncertain.
Do not use for
Do not use this code for blurred vision, visual disturbance, or eye strain without documented double vision. Do not assign it when diplopia is already explained and coded by a more specific diagnosis.
Coding tip
Capture laterality, binocular versus monocular status, and any documented underlying cause to support accurate coding.
