ICD-10 Code H50.022 – Monocular esotropia with A pattern, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.022 – Monocular esotropia with A pattern, left eye
What it is
This code identifies inward turning of the left eye that is present in one eye only and changes with gaze position in an A pattern. Use it when documentation specifies monocular esotropia with an A-pattern deviation.
Clinical signs
Typical findings include the left eye turning inward, with the deviation greater in upgaze than downgaze. Clinical features vary; refer to documentation.
When to use this code
Use H50.022 when the provider documents monocular esotropia affecting the left eye and specifically notes an A pattern. You may also use it when the exam or ophthalmology note clearly supports that pattern and laterality. Check documentation if the record does not distinguish monocular from alternating or unspecified esotropia.
Do not use for
Do not use this code for unspecified esotropia, alternating esotropia, or esotropia without an A-pattern description. If the laterality or pattern is unclear, check documentation.
Coding tip
Capture both laterality and pattern exactly as documented, because missing either detail can lead to a different strabismus code.
