ICD-10 Code H55.82 – Deficient Smooth Pursuit Eye Movements (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H55.82 – Deficient smooth pursuit eye movements
What it is
This code identifies impaired smooth pursuit, the normal ability to follow a moving target with steady eye movements. It describes a neurologic eye-movement abnormality rather than a disease itself.
Clinical signs
Patients may show jerky tracking, frequent catch-up saccades, or inability to maintain smooth eye follow. Clinical features vary; refer to documentation.
When to use this code
Use H55.82 when the record specifically documents deficient smooth pursuit eye movements on exam or testing. It may appear in neurologic, neuro-ophthalmic, or developmental evaluations when the finding is described as a distinct abnormal eye movement pattern.
Use the code when the provider records the finding as an assessment result, not just a vague complaint of blurred vision or dizziness. Check documentation if the note mentions broader nystagmus, gaze palsy, or another primary diagnosis instead.
Do not use for
Do not use this code for general vision loss, eye strain, or nonspecific abnormal eye findings without documented pursuit impairment. Do not substitute it for other ocular motor disorders unless the chart clearly states deficient smooth pursuit.
Coding tip
Code the documented eye-movement abnormality exactly as written and confirm whether a separate neurologic diagnosis also needs reporting.
