I63: ICD10 Code for Cerebral infarction

I63 refers to Cerebral infarction, which includes types of hemorrhagic or ischemic strokes and their sequelae. These conditions affect the blood vessels supplying the brain, causing neurological deficits, long-term disability, or even death without rapid intervention.

Symptoms

• Sudden severe headache – Often described as "thunderclap" in subarachnoid hemorrhage (I60)
• Loss of consciousness or altered mental status – Seen in I60–I62
• Unilateral weakness or numbness – Characteristic of cerebral infarction (I63)
• Slurred speech or difficulty understanding – Indicates cortical involvement
• Vision changes or double vision – May result from posterior circulation stroke
• Transient ischemic symptoms – Occur with I65–I66 without infarction
• Chronic symptoms – Including hemiplegia, aphasia, or cognitive decline (I69)

Diagnosis

Diagnosis of Cerebral infarction involves CT scan, MRI brain, angiography (CTA/MRA), carotid ultrasound, and blood tests. Time-sensitive evaluation determines if thrombolysis or thrombectomy is indicated in ischemic cases. Monitoring and neurosurgical consultation are critical in hemorrhagic strokes.

ICD10 Code Usage

ICD10 code I63 is essential in emergency, neurology, ICU, and rehabilitation settings. It supports acute stroke management, tPA eligibility, long-term disability classification, sequelae tracking (I69), and interventional coding for surgery or rehab.

Related Codes

• I60 – Nontraumatic subarachnoid hemorrhage
• I61 – Nontraumatic intracerebral hemorrhage
• I62 – Other and unspecified nontraumatic intracranial hemorrhage
• I65 – Occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction
• I66 – Occlusion and stenosis of cerebral arteries, not resulting in cerebral infarction
• I67 – Other cerebrovascular diseases
• I68 – Cerebrovascular disorders in diseases classified elsewhere
• I69 – Sequelae of cerebrovascular disease

FAQs

Q1: What is ICD10 code I63?
A: It documents Cerebral infarction, which includes different types of stroke (hemorrhagic and ischemic), vascular narrowing, and post-stroke complications.

Q2: What distinguishes I60–I62?
A: I60 is bleeding into the subarachnoid space; I61 is intracerebral bleeding; I62 includes other or unspecified intracranial hemorrhage types.

Q3: Can artery occlusions (I65–I66) occur without stroke?
A: Yes—these codes are used when arteries are narrowed or blocked without infarction.

Q4: What are I69 sequelae?
A: They refer to long-term effects of stroke such as paralysis, speech loss, or cognitive impairment requiring rehabilitation.

Q5: Who manages these conditions?
A: Stroke teams, neurologists, neurosurgeons, rehabilitation therapists, and primary care physicians collaborate based on phase of care.

Conclusion

ICD10 code I63 ensures proper classification of Cerebral infarction, supporting acute intervention, rehabilitation planning, long-term monitoring, and prevention of recurrent cerebrovascular events.
