ICD-10 Code H50.30 – Unspecified intermittent heterotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.30 – Unspecified intermittent heterotropia
What it is
H50.30 identifies intermittent heterotropia, meaning an eye misalignment that comes and goes rather than staying constant. Use it when the chart does not specify the direction or type of deviation.
Clinical signs
Clinical features vary; refer to documentation. You may see intermittent eye deviation, reduced binocular control, or complaints of occasional double vision. Diagnosis is typically based on the documented ocular misalignment pattern.
When to use this code
Use this code when the provider documents intermittent heterotropia without naming a more specific form. It also fits when the record notes alternating or occasional strabismus but does not identify the exact eye involved. Check documentation if laterality or subtype is stated.
Do not use for
Do not use this code for constant heterotropia or for exotropia/esotropia documented with a specific type. If the note describes a different strabismus pattern, code that documented condition instead.
Coding tip
Code the most specific strabismus term documented; if the chart only says “intermittent heterotropia,” H50.30 is appropriate.
