ICD-10 Code H50.1 – Exotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.1 – Exotropia
What it is
Exotropia is an eye misalignment where one eye turns outward. Use this code for the documented outward deviation of the visual axes.
Clinical signs
Common findings include intermittent or constant outward drifting of one eye, eyes that are not aligned, and possible diplopia or reduced binocular control. Clinical features vary; refer to documentation.
When to use this code
Use H50.1 when the record clearly states exotropia, intermittent exotropia, or outward deviation of an eye. Code it when the clinician documents the condition as the diagnosis being addressed. If the note only says “strabismus” or is unclear, check documentation before coding.
Do not use for
Do not use this code for unspecified strabismus when exotropia is not documented. Do not assign it for a past history of eye deviation without a current diagnosis.
Coding tip
Match the code to the exact eye alignment term in the provider note, and verify laterality or intermittency only if documented.
