ICD-10 Code H50.9 – Unspecified Strabismus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.9 – Unspecified strabismus
What it is
H50.9 identifies strabismus when the eye misalignment is documented but the type is not specified. Use it for crossed eyes, wandering eyes, or other ocular deviation when no more precise diagnosis is recorded.
Clinical signs
Clinical features vary; refer to documentation. Common findings include visible eye misalignment, abnormal ocular positioning, and possible complaints of double vision or poor binocular coordination.
When to use this code
Use this code when the provider documents strabismus but does not identify esotropia, exotropia, hypertropia, or another specific form. It also fits when the record confirms ocular misalignment, but laterality or subtype is not stated.
If the note is unclear, code only what is documented and avoid assuming the exact deviation pattern. Check documentation for the specific type if it affects code selection.
Do not use for
Do not use H50.9 when the record names a more specific strabismus diagnosis. Do not use it for non-strabismic eye movement disorders or for suspected cases without documented confirmation.
Coding tip
Choose the most specific strabismus code available; if the subtype is missing, H50.9 is the correct fallback.
