ICD-10 Code H50.00 – Unspecified Esotropia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H50.00 – Unspecified esotropia
What it is
H50.00 identifies esotropia, a form of strabismus where one or both eyes turn inward. Use this code when the record says esotropia but does not specify the type, laterality, or cause.
Clinical signs
Common findings include inward eye deviation, poor ocular alignment, and possible diplopia or reduced binocular vision. Clinical features vary; refer to documentation.
When to use this code
Use H50.00 when the clinician documents esotropia without further detail. It is appropriate for initial evaluations or notes that do not distinguish accommodative, intermittent, constant, alternating, or monocular forms. If laterality or subtype is documented, code that more specific diagnosis instead.
Do not use for
Do not use this code when the chart specifies a more exact esotropia type or a different strabismus diagnosis. Check documentation if the inward deviation is part of another eye disorder.
Coding tip
Query for laterality, subtype, and any associated condition before defaulting to H50.00.
