Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I63:

Includes

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • occlusion and stenosis of cerebral and precerebral arteries, resulting in cerebral infarction

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
  • code, if applicable, to identify status post administration of tPA rtPA in a different facility within the last 24 hours prior to admission to current facility Z92.82

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • neonatal cerebral infarction P91.82

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • sequelae of cerebral infarction I69.3

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.

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Cerebrovascular diseases (I60-I69)
      • Cerebral infarction (I63)

Code History

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016

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.
