ICD-10 Code H50.332 – Intermittent monocular exotropia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.332 – Intermittent monocular exotropia, left eye
What it is
H50.332 identifies intermittent outward deviation of the left eye that occurs only some of the time. Use it when the left eye drifts outward, but alignment is not constantly present.
Clinical signs
Typical findings include intermittent left-eye exotropia noted on exam or reported by the clinician. Clinical features vary; refer to documentation for whether the deviation is monocular, intermittent, and left-sided.
When to use this code
Use this code when documentation clearly states intermittent monocular exotropia affecting the left eye. It fits ophthalmology or optometry notes describing alternating alignment with one eye drifting outward at times. If laterality or intermittency is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for constant exotropia, alternating exotropia, or right-eye involvement. Do not assign it when the record only says “strabismus” or “eye deviation” without the required detail.
Coding tip
Confirm both intermittency and left-eye laterality in the provider’s note before coding H50.332.
