I63.6 is the authoritative medical code for Cerebral infarction due to cerebral venous thrombosis, nonpyogenic. This classification is used in medical billing and clinical recording to specify the clinical criteria for cerebral infarction due to cerebral venous thrombosis, nonpyogenic (ICD-10-CM I63.6), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Official Registry Overview & Definition
Cerebral infarction due to cerebral venous thrombosis, nonpyogenic is a billable ICD-10-CM diagnosis code I63.6. Includes: occlusion and stenosis of cerebral and precerebral arteries, resulting in cerebral infarction. Excludes1 (not coded here): neonatal cerebral infarction P91.82-; traumatic intracranial hemorrhage S06.-. Excludes2 (not included here): chronic, without residual deficits sequelae Z86.73; sequelae of cerebral infarction I69.3-. Use 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; code, if known, to indicate National Institutes of Health Stroke Scale NIHSS score R29.7-; code to identify presence of:; alcohol abuse and dependence F10.-; exposure to environmental tobacco smoke Z77.22; history of tobacco dependence Z87.891; hypertension I10-I1A; occupational exposure to environmental tobacco smoke Z57.31; tobacco dependence F17.-; tobacco use Z72.0.

Frequently Asked Questions (FAQ) & Clinical Guidance
What can't be coded together with I63.6?
Per Excludes1 instructions, I63.6 must not be reported with: neonatal cerebral infarction (P91.82-); traumatic intracranial hemorrhage (S06.-).
Can I63.6 be reported alongside related conditions?
Per Excludes2 instructions, I63.6 and the following may both be reported when both are present: chronic, without residual deficits (sequelae) (Z86.73); sequelae of cerebral infarction (I69.3-).
Is an additional code needed with I63.6?
Use additional code(s) to specify: 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); code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-); code to identify presence of:; alcohol abuse and dependence (F10.-).
