ICD-10 Code H50.03 – Monocular esotropia with V pattern (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.03 – Monocular esotropia with V pattern
What it is
H50.03 identifies inward eye deviation in one eye with a V-pattern, meaning the amount of esotropia changes between upgaze and downgaze. Use it when the documentation specifies monocular esotropia with this pattern.
Clinical signs
Typical findings include one eye turning inward, with the deviation greater in upgaze or downgaze in a V-pattern. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents monocular esotropia and specifically notes a V-pattern. It may also apply when the record describes pattern strabismus with inward deviation affecting one eye. Check documentation if laterality or pattern is unclear.
Do not use for
Do not use it for exotropia, intermittent esotropia, or esotropia without a documented V-pattern. Do not assign it when the chart does not clearly identify monocular involvement.
Coding tip
Confirm both the pattern and the monocular nature of the esotropia before assigning H50.03.
