ICD-10 Code H50.142 – Monocular exotropia with other noncomitancies, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.142 – Monocular exotropia with other noncomitancies, left eye
What it is
H50.142 identifies a left-eye exotropia, meaning the eye turns outward, with noncomitant findings. The deviation changes with gaze direction, so the misalignment is not the same in all positions.
Clinical signs
You may see outward deviation of the left eye, unequal alignment in different gaze positions, and possible diplopia or head turn. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents monocular exotropia of the left eye with noncomitant behavior. It fits ophthalmology or specialist notes describing gaze-dependent misalignment. Check documentation if laterality or comitancy is unclear.
Do not use for
Do not use it for alternating exotropia, unspecified exotropia, or comitant strabismus. Also avoid it when the chart does not confirm the left eye or noncomitant pattern.
Coding tip
Verify both laterality and noncomitancy in the exam note before assigning H50.142.
