ICD-10 Code G96.12 – Meningeal adhesions (cerebral) (spinal) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96.12 – Meningeal adhesions (cerebral) (spinal)
What it is
Meningeal adhesions are abnormal scar-like bands that bind the meninges around the brain or spinal cord. They can restrict normal movement or fluid flow and may reflect prior inflammation, surgery, or bleeding.
Clinical signs
Clinical features vary; refer to documentation. Patients may have pain, neurologic deficits, or symptoms related to impaired cerebrospinal fluid circulation, depending on the adhesion location and severity.
When to use this code
Use G96.12 when the provider documents cerebral or spinal meningeal adhesions as the diagnosed condition. Apply it for confirmed adhesions seen on imaging, during surgery, or in specialist assessment. Check documentation if adhesions are only suspected or described indirectly.
Do not use for
Do not use this code for general meningitis, meningeal irritation, or nonspecific scarring without documented adhesions. If the record identifies a different neurologic disorder as the main issue, code that condition instead.
Coding tip
Code G96.12 only when the record clearly states meningeal adhesions and identifies whether they are cerebral or spinal.
