Ataxia following other nontraumatic intracranial hemorrhage

This code describes the presence of ataxia, a neurological sign characterized by impaired coordination of voluntary movements, as a sequela of a nontraumatic intracranial hemorrhage other than subarachnoid or intracerebral hemorrhage. This condition represents a long-term neurological deficit resulting from a previous bleeding event within the skull not caused by trauma.

Use this code when documentation clearly indicates that a patient is experiencing ataxia that is directly attributed to a past nontraumatic intracranial hemorrhage, such as an intraventricular hemorrhage or other specified nontraumatic intracranial hemorrhage. The medical record should specify the type of nontraumatic hemorrhage and the resulting ataxia.

• Always sequence this code after the code identifying the specific type of nontraumatic intracranial hemorrhage (e.g., I61.x, I62.x) if the hemorrhage is still active.
• Ensure documentation specifies "nontraumatic" to differentiate from sequelae of traumatic brain injury.
• Do not use this code for ataxia due to active hemorrhage or other causes; it is specifically for sequelae.
