ICD-10 Code H51 – Other disorders of binocular movement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H51 – Other disorders of binocular movement
What it is
H51 identifies disorders affecting coordinated eye movement between the two eyes. Use it when the chart documents abnormal binocular movement that does not fit a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see impaired eye coordination, abnormal gaze alignment, or difficulty moving both eyes together in a controlled way.
When to use this code
Use H51 when the provider documents a binocular movement disorder without naming a more specific condition. It can apply when the note describes abnormal conjugate eye movement, ocular motility problems, or related coordination deficits. If the record is unclear, check documentation before coding.
Do not use for
Do not use H51 for isolated refractive errors, eyelid disorders, or unrelated neurologic symptoms. If the provider specifies a different eye movement diagnosis, code that condition instead.
Coding tip
Code the most specific documented eye movement disorder first; use H51 only when the record supports a nonspecific binocular movement problem.
