ICD-10 Code H51.8 – Other specified disorders of binocular movement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H51.8 – Other specified disorders of binocular movement
What it is
H51.8 identifies binocular movement disorders that do not fit a more specific ICD-10 category. Use it when the record describes abnormal coordinated eye movement between both eyes, but a named diagnosis is not documented.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include impaired eye coordination, difficulty tracking objects, or abnormal alignment during gaze testing.
When to use this code
Use H51.8 when the clinician documents an unspecified but clearly described disorder of binocular movement and no more specific code applies. It may support outpatient, specialist, or problem-list coding when the assessment names a binocular motility abnormality. Check documentation if the note only mentions vague visual complaints.
Do not use for
Do not use this code for conditions with a more specific diagnosis, such as strabismus or other named ocular motility disorders. If the chart does not clearly describe a binocular movement disorder, check documentation.
Coding tip
Match the code to the provider’s exact wording and code the most specific eye-movement diagnosis available.
