2025 ICD-10-CM code I63.6
(Active) Effective Date: N/A Diseases of the circulatory system - Cerebrovascular diseases 9 Feed
Cerebral infarction due to cerebral venous thrombosis, nonpyogenic.
Medical necessity for I63.6 relies on documented evidence of cerebral venous thrombosis causing cerebral infarction, distinguished from other types of stroke. The documentation must support the diagnosis and the need for related interventions.
Neurologists typically manage I63.6. Diagnosis involves neuroimaging (CT, MRI, MRV) and potentially, other tests to rule out infectious causes. Treatment focuses on managing the underlying cause, preventing further clot formation, and addressing neurological deficits.
In simple words: A stroke caused by a blood clot in the veins of the brain, not due to an infection.
Cerebral infarction resulting from a blockage in the cerebral venous system due to non-infectious thrombosis. This condition involves the formation of a blood clot within the veins responsible for draining blood from the brain, leading to an obstruction of blood flow and subsequent tissue death (infarction) in the affected brain region.It is crucial to distinguish this from infectious thrombosis (septic thrombophlebitis).
Example 1: A 35-year-old woman presents with headache, blurred vision, and seizures. Imaging reveals cerebral venous thrombosis and subsequent infarction, confirmed as nonpyogenic. I63.6 is used for the cerebral infarction, and additional codes may specify the location and extent of the thrombosis., A patient with a history of deep vein thrombosis (DVT) develops neurological symptoms.Diagnostic imaging confirms a cerebral venous thrombosis leading to infarction, without evidence of infection. Code I63.6 is applied, along with a code for the history of DVT., A postpartum woman experiences severe headaches and focal neurological deficits. Investigations reveal cerebral venous thrombosis with resulting infarction, not associated with infection.Code I63.6 is assigned, along with codes related to the postpartum state.
Documentation should include details from imaging studies (CT, MRI, MRV) confirming cerebral venous thrombosis and the resulting infarction.Lab results excluding infection/sepsis, details of neurological examination, and any underlying conditions should also be documented.
