Ataxia, unspecified

This code represents a general diagnosis of ataxia, which is a neurological sign characterized by a lack of voluntary coordination of muscle movements. It manifests as impaired balance, gait, speech, and eye movements, indicating dysfunction in the cerebellum or its connections. This code is used when the specific underlying cause of the ataxia is unknown or not documented.

Use this code when the medical record clearly documents "ataxia" without further specification of its etiology. This applies to situations where the clinician has identified ataxia but has not yet determined if it's due to a specific disease, injury, or other identifiable cause. Supporting documentation would include physician notes describing the patient's uncoordinated movements, gait disturbances, or balance issues, explicitly stating "ataxia, unspecified."

• Avoid using this code if the documentation specifies a known cause for the ataxia; instead, code the specific condition.
• Per the Excludes1 note, never code this alongside codes for ataxia specifically documented as following cerebrovascular disease.
• Always query the provider for greater specificity if the documentation simply states "ataxia" and further investigation is ongoing or results are pending.
