ICD-10-CM Code I63.89

Other cerebral infarction

Version 2021 Billable Code

Valid for Submission

I63.89 is a billable code used to specify a medical diagnosis of other cerebral infarction. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code I63.89 might also be used to specify conditions or terms like cerebellar stroke syndrome, cerebral infarction due to cerebral artery occlusion, cerebral ischemic stroke due to aortic arch embolism, cerebral ischemic stroke due to dissection of artery, cerebral ischemic stroke due to global hypoperfusion with watershed infarct, cerebral ischemic stroke due to hypercoagulable state, etc

Short Description:Other cerebral infarction
Long Description:Other cerebral infarction

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I63.89 are found in the index:


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Cerebellar stroke syndrome
  • Cerebral infarction due to cerebral artery occlusion
  • Cerebral ischemic stroke due to aortic arch embolism
  • Cerebral ischemic stroke due to dissection of artery
  • Cerebral ischemic stroke due to global hypoperfusion with watershed infarct
  • Cerebral ischemic stroke due to hypercoagulable state
  • Cerebral ischemic stroke due to subarachnoid hemorrhage
  • Chronic cerebrovascular accident
  • Embolic infarction
  • Hemorrhagic cerebral infarction
  • Infarct of cerebrum due to iatrogenic cerebrovascular accident
  • Infarction of basal ganglia
  • Left sided cerebral infarction
  • Paralytic stroke
  • Periventricular hemorrhagic venous infarct
  • Posterior circulation stroke of uncertain pathology
  • Right sided cerebral hemisphere cerebrovascular accident
  • Right sided cerebral infarction
  • Stroke of uncertain pathology
  • Superior cerebellar artery syndrome
  • Thalamic infarction

Clinical Information

  • CEREBRAL INFARCTION-. the formation of an area of necrosis in the cerebrum caused by an insufficiency of arterial or venous blood flow. infarcts of the cerebrum are generally classified by hemisphere i.e. left vs. right lobe e.g. frontal lobe infarction arterial distribution e.g. infarction anterior cerebral artery and etiology e.g. embolic infarction.
  • INFARCTION MIDDLE CEREBRAL ARTERY-. necrosis occurring in the middle cerebral artery distribution system which brings blood to the entire lateral aspects of each cerebral hemisphere. clinical signs include impaired cognition; aphasia; agraphia; weak and numbness in the face and arms contralaterally or bilaterally depending on the infarction.

Replacement Code

Information for Patients

Ischemic Stroke

Also called: Embolic Stroke, Thrombotic stroke

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Ischemic stroke is the most common type. It is usually caused by a blood clot that blocks or plugs a blood vessel in the brain. This keeps blood from flowing to the brain. Within minutes, brain cells begin to die. Another cause is stenosis, or narrowing of the artery. This can happen because of atherosclerosis, a disease in which plaque builds up inside your arteries. Transient ischemic attacks (TIAs) occur when the blood supply to the brain is interrupted briefly. Having a TIA can mean you are at risk for having a more serious stroke.

Symptoms of stroke are

  • Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
  • Sudden confusion, trouble speaking or understanding speech
  • Sudden trouble seeing in one or both eyes
  • Sudden trouble walking, dizziness, loss of balance or coordination
  • Sudden severe headache with no known cause

It is important to treat strokes as quickly as possible. Blood thinners may be used to stop a stroke while it is happening by quickly dissolving the blood clot. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage.
