Nontraumatic extradural hemorrhage

This code signifies bleeding that occurs outside the dura mater of the brain or spinal cord, not caused by an injury. It represents a collection of blood in the extradural space, often resulting from a ruptured blood vessel. This condition can lead to increased intracranial pressure and neurological deficits.

Use this code for spontaneous extradural hemorrhages, such as those caused by an underlying vascular malformation, aneurysm, or coagulopathy. Documentation should clearly state "nontraumatic" or "spontaneous" extradural hemorrhage, and specify the location (e.g., intracranial, spinal). This code is appropriate when trauma has been explicitly ruled out as the cause.

• Differentiate carefully between traumatic and nontraumatic etiologies; the documentation must explicitly support the nontraumatic nature.
• Do not use this code if the hemorrhage is a direct result of an injury; instead, refer to codes for traumatic intracranial hemorrhage.
• Consider additional codes for any underlying conditions contributing to the hemorrhage, such as hypertension or coagulopathy.
