Cerebral infarction (I63)

Browse all the diagnosis codes used for cerebral infarction (i63). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

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).

Embolic Stroke - An ischemic stroke due to a blood clot, emboli or other types of blockage which forms somewhere other than the brain and subsequently travels near and restricts blood flow to the brain. Most often the origin of the clot is from the heart and is referred to as cardioembolic stroke.

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.

Ischemic Stroke - Stroke due to BRAIN ISCHEMIA resulting in interruption or reduction of blood flow to a part of the brain. When obstruction is due to a BLOOD CLOT formed within in a cerebral blood vessel it is a thrombotic stroke. When obstruction is formed elsewhere and moved to block a cerebral blood vessel (see CEREBRAL EMBOLISM) it is referred to as embolic stroke. Wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.

Livedo Reticularis - A condition characterized by a reticular or fishnet pattern on the skin of lower extremities and other parts of the body. This red and blue pattern is due to deoxygenated blood in unstable dermal blood vessels. The condition is intensified by cold exposure and relieved by rewarming.

Livedoid Vasculopathy - A rare cutaneous thrombotic disease due to occlusion of dermal vessels. It is characterized by purpuric maculae and ulcerations especially during summer which form scars called atrophie blanche. It is more associated with other syndromes (e.g., PROTEIN C DEFICIENCY; HYPERHOMOCYSTEINEMIA). Livedo reticularis with systemic involvement and stroke is SNEDDON SYNDROME.

Sneddon Syndrome - A systemic non-inflammatory arteriopathy primarily of middle-aged females characterized by the association of LIVEDO RETICULARIS, multiple thrombotic CEREBRAL INFARCTION; CORONARY DISEASE, and HYPERTENSION. Elevation of antiphospholipid antibody titers (see also ANTIPHOSPHOLIPID SYNDROME), cardiac valvulopathy, ISCHEMIC ATTACK, TRANSIENT; SEIZURES; DEMENTIA; and chronic ischemia of the extremities may also occur. Pathologic examination of affected arteries reveals non-inflammatory adventitial fibrosis, thrombosis, and changes in the media. (From Jablonski, Dictionary of Syndromes & Eponymic Diseases, 2d ed; Adams et al., Principles of Neurology, 6th ed, p861; Arch Neurol 1997 Jan;54(1):53-60)

Thrombotic Stroke - A type of ischemic stroke resulting from obstruction due to a BLOOD CLOT formed within in a CEREBRAL ARTERY often associated with ATHEROSCLEROSIS. A stroke due to a blood clot in a cerebral vein is a venous infarction (see VENOUS INFARCTION, BRAIN).

Instructional Notations

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

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

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

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.
