ICD-10 Code D32.9 – Benign neoplasm of meninges, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D32.9 – Benign neoplasm of meninges, unspecified
What it is
D32.9 identifies a noncancerous tumor arising from the meninges, the membranes covering the brain and spinal cord, when the site is not further specified. Use it when the record confirms a benign meningeal neoplasm but does not name a more precise location.
Clinical signs
Clinical features vary; refer to documentation. Benign meningeal tumors may be found on imaging or after symptoms from pressure on adjacent structures, such as headache, seizures, or focal neurologic findings.
When to use this code
Use D32.9 when the provider documents a benign neoplasm of the meninges and the chart does not specify the exact meningeal site. It also fits when pathology or imaging confirms a benign meningeal mass, but the anatomic detail is unavailable in the note.
Do not use for
Do not use this code for malignant or uncertain neoplasms, or for meningioma with a more specific meningeal site documented. If the record describes a different intracranial or spinal lesion, check documentation.
Coding tip
Query for the exact meningeal location before assigning the unspecified code.
