ICD-10 Code H50.0 – Esotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.0 – Esotropia
What it is
Esotropia is a form of strabismus in which one eye turns inward toward the nose. Use this code when the record documents a manifest inward deviation, whether constant or intermittent.
Clinical signs
Typical findings include inward eye misalignment, possible double vision, and poor binocular coordination. Clinical features vary; refer to documentation.
When to use this code
Use H50.0 when the provider documents esotropia, inward deviation, or convergent strabismus as the diagnosis. It also applies when the note identifies a specific esotropia type but still uses the general esotropia diagnosis. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for exotropia or other non-inward ocular deviations. Do not assign it when the chart only notes suspected misalignment without a confirmed diagnosis.
Coding tip
Match the code to the provider’s exact wording and confirm whether the deviation is manifest, not just a history of eye crossing.
