ICD-10 Code H50.131 – Monocular exotropia with V pattern, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.131 – Monocular exotropia with V pattern, right eye
What it is
This code identifies outward deviation of the right eye that follows a V-pattern. Use it when the record specifically states monocular exotropia with V pattern affecting the right eye.
Clinical signs
Typical findings include the right eye drifting outward, with the deviation changing between upgaze and downgaze in a V-shaped pattern. Clinical features vary; refer to documentation.
When to use this code
Use H50.131 when the clinician documents monocular exotropia with V pattern in the right eye. It is appropriate for ophthalmology or optometry notes that clearly identify laterality and the V-pattern alignment abnormality.
Do not use for
Do not use this code for unspecified exotropia, alternating exotropia, or horizontal strabismus without a V pattern. Check documentation if laterality or pattern is not clearly stated.
Coding tip
Confirm both laterality and the V-pattern term in the assessment before assigning this code.
