Intermittent alternating esotropia

This code describes a type of strabismus where one eye deviates inward (esotropia), and the deviation alternates between the left and right eye. The misalignment is not constant, meaning the patient can fixate with either eye, while the other eye turns inward. This condition affects binocular vision and can lead to amblyopia if not managed.

Use this code when documentation clearly indicates an intermittent inward turning of the eye that alternates between the left and right eyes. This diagnosis is typically made by an ophthalmologist or optometrist during an eye examination. Supporting documentation should specify "intermittent," "alternating," and "esotropia."

• Differentiate from constant alternating esotropia (H50.22) or monocular intermittent esotropia (H50.31-).
• Ensure the documentation specifies "alternating" to distinguish it from intermittent monocular esotropia.
• Consider laterality if the documentation specifies a predominant eye, though this code inherently implies both eyes are involved in the alternation.
