ICD-10 Code H50.031 – Monocular esotropia with V pattern, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.031 – Monocular esotropia with V pattern, right eye
What it is
This code identifies inward eye deviation affecting the right eye, with a V-pattern change in alignment across gaze positions. Use it when the chart specifically documents monocular esotropia with V pattern on the right.
Clinical signs
Typical findings include right-eye esodeviation that changes with upgaze and downgaze, often more noticeable in certain directions of gaze. Clinical features vary; refer to documentation.
When to use this code
Use H50.031 when the provider clearly documents monocular esotropia with V pattern in the right eye. It also fits ophthalmology notes describing pattern strabismus with laterality confirmed as right eye. Check documentation if the record only says esotropia or pattern deviation without laterality.
Do not use for
Do not use this code for unspecified esotropia, alternating strabismus, or a different pattern such as A pattern. If the right eye is not identified, or the diagnosis is uncertain, check documentation.
Coding tip
Capture both the pattern and the eye laterality exactly as documented to avoid using an unspecified strabismus code.
