ICD-10 Code I63.6: Cerebral infarction due to cerebral venous thrombosis, nonpyogenic

I63.6 is a billable ICD-10 diagnosis code used to classify Cerebral infarction due to cerebral venous thrombosis, nonpyogenic in medical records and claims. You may see this code in hospital records, discharge summaries, insurance claims, encounter documentation, referrals, or other healthcare billing and coding records. ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the circulatory system (I00-I99).

What is this code?

ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the circulatory system (I00-I99).

đź“‹Clinical overview

This ICD-10 code is commonly used when documentation describes cerebral infarction attributed to nonpyogenic cerebral venous thrombosis. The final code is distinct from the more common arterial thrombosis, embolic, or unspecified-occlusion ischemic-stroke branches.

When is it used?

  • May be used when a clinician documents cerebral infarction due to cerebral venous thrombosis, nonpyogenic in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.
  • This code can be used as a clinically usable diagnosis entry in standardized coding workflows.

What it does not mean

  • A code alone does not explain severity, treatment plan, or outcome.
  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.

đź©şClinical context

When commonly used
  • Stroke, neurology, inpatient, and utilization-review documentation where cerebral infarction is linked to cerebral venous thrombosis rather than an arterial mechanism.
  • Coding workflows where the chart clearly identifies nonpyogenic cerebral venous thrombosis as the cause of the infarction.
Common management context
  • Evaluation often includes neurologic examination, brain imaging review, venous-thrombosis assessment context, and follow-up of ischemic deficits or prothrombotic risk factors.
  • Documentation becomes more specific when the chart clearly distinguishes venous thrombosis from arterial thrombosis, embolism, or hemorrhagic stroke.
  • Specialist context already linked on this page includes Cardiologist, General Physician, Neurologist, Stroke Specialist.

🔍Key distinctions

Important notes
  • This ICD-10 code describes ischemic stroke attributed to cerebral venous thrombosis rather than the more common arterial cerebral-infarction mechanisms.
  • The nonpyogenic venous-thrombosis mechanism is part of the code definition and separates this branch from arterial occlusive disease.
  • This title reflects ischemic stroke attributed to nonpyogenic cerebral venous thrombosis, which is coded separately from the more common arterial thrombosis, embolic, or unspecified-occlusion cerebral-infarction branches.
  • Documentation that links cerebral infarction to cerebral venous thrombosis is coded differently from infarction attributed to precerebral or cerebral arterial disease.
