ICD-10 Code H50.34 – Intermittent alternating exotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.34 – Intermittent alternating exotropia
What it is
Intermittent alternating exotropia is an eye alignment disorder where one eye or the other drifts outward, but not constantly. The deviation comes and goes, and either eye may fixate.
Clinical signs
You may see outward eye deviation that appears intermittently, often more noticeable when the patient is tired or daydreaming. Clinical features vary; refer to documentation.
When to use this code
Use H50.34 when the record clearly documents intermittent exotropia with alternating fixation between the eyes. Code it for confirmed strabismus diagnoses in ophthalmology or optometry notes. Check documentation if the note only says exotropia without the intermittent or alternating detail.
Do not use for
Do not use this code for constant exotropia, esotropia, or unspecified strabismus. If the chart does not state alternating involvement, check documentation before assigning H50.34.
Coding tip
Look for both elements: intermittent outward deviation and alternating eye fixation.
