ICD-10 Code H50.311 – Intermittent monocular esotropia, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.311 – Intermittent monocular esotropia, right eye
What it is
H50.311 identifies intermittent inward turning of the right eye that occurs only part of the time. You use it when the deviation is monocular and limited to the right eye.
Clinical signs
Findings may include occasional right-eye esodeviation, eye misalignment that comes and goes, and possible reduced binocular control. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states intermittent monocular esotropia affecting the right eye. It fits ophthalmology or optometry documentation describing a right-eye inward turn that is not constant. Check documentation if the note does not specify laterality or whether the deviation is intermittent.
Do not use for
Do not use H50.311 for constant esotropia, alternating esotropia, or left-eye involvement. Do not assign it when the provider documents only nonspecific strabismus. Check documentation.
Coding tip
Match both laterality and intermittency exactly as documented before assigning H50.311.
