ICD-10 Code H50.04 – Monocular esotropia with other noncomitancies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.04 – Monocular esotropia with other noncomitancies
What it is
Use this code for a convergent eye deviation affecting one eye, with misalignment that does not stay the same in all gaze positions. It identifies a monocular esotropia with associated noncomitant features.
Clinical signs
Clinical features vary; refer to documentation. You may see inward turning of one eye, unequal alignment in different directions of gaze, and possible diplopia or abnormal head posture.
When to use this code
Use H50.04 when the provider documents monocular esotropia and specifically notes other noncomitancies. This fits ophthalmology or optometry assessments where the deviation changes with gaze or is described as noncomitant. Do not infer the diagnosis from strabismus alone; check documentation.
Do not use for
Do not use this code for comitant esotropia, intermittent misalignment without the documented noncomitant pattern, or unspecified strabismus. If the record does not clearly support the subtype, check documentation.
Coding tip
Confirm both laterality and the noncomitant description in the note before assigning H50.04.
