ICD-10 Code H50.132 – Monocular exotropia with V pattern, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.132 – Monocular exotropia with V pattern, left eye
What it is
This code identifies outward eye deviation in the left eye with a V-pattern, meaning the amount of exotropia changes between upgaze and downgaze. Use it when documentation specifies the left eye and the V-pattern alignment issue.
Clinical signs
Typical findings include intermittent or constant outward drift of the left eye, with the deviation increasing or decreasing in a V-shaped pattern on gaze testing. Clinical features vary; refer to documentation.
When to use this code
Use H50.132 when the provider documents monocular exotropia affecting the left eye and specifically notes a V pattern. It is appropriate for ophthalmology or optometry assessments that record gaze-dependent misalignment. Do not assume the pattern or laterality if the note is incomplete; check documentation.
Do not use for
Do not use this code for unspecified exotropia, alternating exotropia, or other pattern types such as A pattern. If the record does not clearly identify the left eye or V pattern, check documentation.
Coding tip
Confirm both laterality and the V-pattern detail in the exam note before assigning H50.132.
