ICD-10 Code G93.5 – Compression of brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G93.5 – Compression of brain
What it is
G93.5 identifies compression of the brain, a condition where pressure on brain tissue is documented. It is a diagnosis code for the underlying anatomic problem, not a symptom-only complaint.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include altered mental status, focal neurologic deficits, headache, or signs of increased intracranial pressure.
When to use this code
Use G93.5 when the provider documents brain compression as the diagnosis or a confirmed imaging-based finding. It may apply in trauma, mass effect, edema, hemorrhage, or other intracranial processes causing pressure on the brain.
Code it only when the record supports compression rather than a nonspecific neurologic complaint. If the documentation instead describes a mass, hemorrhage, or edema without stating compression, check documentation before assigning this code.
Do not use for
Do not use G93.5 for general headache, concussion, or altered consciousness without documented brain compression. Avoid using it when the record only notes an intracranial lesion or swelling and does not confirm compression.
Coding tip
Assign G93.5 only when the provider clearly links the brain compression to the encounter documentation.
