ICD-10 Code H50.3 – Intermittent heterotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.3 – Intermittent heterotropia
What it is
H50.3 identifies intermittent heterotropia, a form of strabismus where one eye occasionally turns out of alignment. The deviation is not constant and may appear only at certain times or viewing conditions.
Clinical signs
Clinical features vary; refer to documentation. Common findings include intermittent eye misalignment, reduced binocular control, or a drifting eye noted on exam, especially when the patient is tired or inattentive.
When to use this code
Use H50.3 when the record clearly documents intermittent heterotropia or intermittent strabismus affecting eye alignment. Apply it for outpatient, specialist, or problem-list documentation when the provider identifies the condition by name. If the note only says “eye turns sometimes,” check documentation for a more specific diagnosis.
Do not use for
Do not use this code for constant heterotropia, heterophoria, or unspecified strabismus without intermittent features. If the documentation does not confirm intermittent deviation, check documentation.
Coding tip
Code from the provider’s exact terminology and confirm whether the deviation is intermittent before assigning H50.3.
