Nontraumatic extradural hemorrhage

This code represents bleeding that occurs in the extradural space (between the dura mater and the skull or vertebral column) that is not caused by trauma. This condition is typically spontaneous and can be associated with underlying vascular malformations, coagulopathies, or tumors.

Use this code when documentation clearly indicates an extradural hemorrhage without any history or evidence of traumatic injury. This often applies to cases of spontaneous epidural hematomas in the cranial or spinal regions. Supporting documentation should explicitly state "nontraumatic" or "spontaneous" extradural hemorrhage.

• Differentiate carefully between traumatic and nontraumatic etiologies; if trauma is present, a code from the S06.xxx or S20.xxx series would be more appropriate.
• Always review the medical record for the cause of the hemorrhage; if a specific underlying condition (e.g., arteriovenous malformation, tumor) is identified, it should be coded as a primary or secondary diagnosis.
• Do not confuse with subarachnoid or subdural hemorrhages, which involve different anatomical spaces and have distinct ICD-10-CM codes.
