Specific Coding for Cerebral infarction due to thrombosis of precerb arteries

Non-specific codes like I63.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for cerebral infarction due to thrombosis of precerb arteries:

  • BILLABLE CODE - Use I63.00 for Cerebral infarction due to thrombosis of unspecified precerebral artery
  • NON-BILLABLE CODE - I63.01 for Cerebral infarction due to thrombosis of vertebral artery
  • BILLABLE CODE - Use I63.011 for Cerebral infarction due to thrombosis of right vertebral artery
  • BILLABLE CODE - Use I63.012 for Cerebral infarction due to thrombosis of left vertebral artery
  • BILLABLE CODE - Use I63.013 for Cerebral infarction due to thrombosis of bilateral vertebral arteries
  • BILLABLE CODE - Use I63.019 for Cerebral infarction due to thrombosis of unspecified vertebral artery
  • BILLABLE CODE - Use I63.02 for Cerebral infarction due to thrombosis of basilar artery
  • NON-BILLABLE CODE - I63.03 for Cerebral infarction due to thrombosis of carotid artery
  • BILLABLE CODE - Use I63.031 for Cerebral infarction due to thrombosis of right carotid artery
  • BILLABLE CODE - Use I63.032 for Cerebral infarction due to thrombosis of left carotid artery
  • BILLABLE CODE - Use I63.033 for Cerebral infarction due to thrombosis of bilateral carotid arteries
  • BILLABLE CODE - Use I63.039 for Cerebral infarction due to thrombosis of unspecified carotid artery
  • BILLABLE CODE - Use I63.09 for Cerebral infarction due to thrombosis of other precerebral artery

Ischemic Stroke

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Ischemic stroke is the more 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:

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.
