ICD-10 Code H50.32 – Intermittent alternating esotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.32 – Intermittent alternating esotropia
What it is
H50.32 identifies intermittent alternating esotropia, a form of strabismus where one eye turns inward at times, then the other eye may take over. The deviation is not constant and alternates between eyes.
Clinical signs
You may see intermittent inward deviation, alternating fixation, and possible eye misalignment that becomes more obvious with fatigue or inattention. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states intermittent alternating esotropia or equivalent wording. It is appropriate for outpatient, specialty, or problem-list documentation when the diagnosis is confirmed by the clinician. Check documentation if laterality, constancy, or type of deviation is unclear.
Do not use for
Do not use this code for constant esotropia, exotropia, or unspecified strabismus. If the chart does not confirm alternating involvement, check documentation before assigning H50.32.
Coding tip
Code only when the provider documents both intermittency and alternating esotropia; otherwise, query or use the more specific documented strabismus code.
