What This Code Means

Bleeding between the skull and the outermost membrane covering the brain (epidural space), not caused by trauma.

Coding Tips

•Extradural hemorrhages are less common than subdural; confirm location on imaging reports
•Ensure nontraumatic etiology is documented to distinguish from traumatic epidural hemorrhage

Clinical Significance

Nontraumatic extradural (epidural) hemorrhage is a rare but serious condition involving bleeding between the skull and the outermost dural membrane, typically caused by arterial bleeding not related to trauma. Unlike the more common traumatic epidural hemorrhage, nontraumatic cases may be associated with coagulopathy, infections, or vascular malformations. This diagnosis reflects high-acuity neurological care needs and is important for risk adjustment.

Documentation Requirements

✓Imaging confirmation (CT) showing lens-shaped (biconvex) epidural collection
✓Clear documentation that the hemorrhage is nontraumatic in origin
✓Evaluation for underlying causes such as coagulopathy, infection, or dural arteriovenous fistula
✓Neurological examination and monitoring documentation
✓Documentation ruling out traumatic causes, especially recent head injury
✓Neurosurgical evaluation and treatment plan

Commonly Confused Codes

S06.4X — Traumatic epidural hemorrhage; the traumatic version is far more common I62.00-I62.03 — Nontraumatic subdural hemorrhage; bleeding beneath the dura, not above it I61.9 — Intracerebral hemorrhage; bleeding within the brain tissue itself I62.9 — Unspecified nontraumatic intracranial hemorrhage; less specific code
