ICD-10 Code H50.13 – Monocular exotropia with V pattern (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.13 – Monocular exotropia with V pattern
What it is
H50.13 identifies a monocular exotropia with a V pattern, meaning one eye turns outward and the deviation changes with gaze direction in a V-shaped pattern. Use it when documentation specifies this exact strabismus pattern.
Clinical signs
Typical findings include outward deviation of one eye that is greater in upgaze or downgaze, depending on the pattern described. Clinical features vary; refer to documentation.
When to use this code
Use H50.13 when the clinician documents monocular exotropia with a V pattern on exam or in the assessment. It also fits when the record clearly states the pattern and laterality is not needed beyond monocular exotropia. Check documentation if the note only says exotropia without pattern details.
Do not use for
Do not use this code for esotropia, intermittent exotropia, or exotropia without a documented V pattern. If the eye deviation type or pattern is unclear, check documentation.
Coding tip
Code only when both monocular exotropia and V pattern are explicitly documented.
