ICD-10 Code H50.2 – Vertical Strabismus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.2 – Vertical strabismus
What it is
Vertical strabismus is an eye misalignment in which one eye turns upward or downward relative to the other. Use this code when the deviation is specifically vertical and documented as such.
Clinical signs
Common findings include one eye appearing higher or lower than the other, with possible diplopia or compensatory head posture. Clinical features vary; refer to documentation.
When to use this code
Use H50.2 when the provider documents vertical strabismus, hypertropia, hypotropia, or a vertical ocular deviation without a more specific diagnosis. It may apply in outpatient assessment, ophthalmology notes, or problem lists when the condition is being evaluated or followed. Check documentation if the record does not clearly specify the direction or type.
Do not use for
Do not use this code for horizontal strabismus, intermittent misalignment, or nonspecific “eye turning” without vertical deviation documented. If the chart describes another ocular motility disorder, code the documented condition instead.
Coding tip
Look for the exact direction of the deviation in the note before assigning H50.2.
