Deficient smooth pursuit eye movements

This code describes an impairment in the ability of the eyes to smoothly track a moving object. This can manifest as jerky or saccadic eye movements when attempting to follow a target, rather than a continuous, fluid gaze. It indicates a dysfunction in the neurological pathways responsible for maintaining steady fixation on a moving stimulus.

Use this code when documentation explicitly states "deficient smooth pursuit," "impaired smooth pursuit," or "saccadic pursuit." This condition is often noted during neurological examinations, ophthalmological assessments, or when evaluating patients with suspected brainstem, cerebellar, or cortical lesions affecting oculomotor control.

• Ensure the documentation clearly specifies "smooth pursuit" and not other types of eye movement deficits (e.g., saccades, nystagmus).
• Consider sequencing this code after a more definitive diagnosis if the deficient smooth pursuit is a symptom of an underlying neurological condition.
• Do not use this code for normal, age-related decline in smooth pursuit unless specifically documented as deficient or impaired.
