Benign neoplasm of spinal meninges

This code identifies a non-cancerous tumor originating from the membranes (meninges) surrounding the spinal cord. These tumors are typically slow-growing and do not metastasize, but their location can cause neurological symptoms due to compression of the spinal cord or nerve roots.

Apply this code when documentation confirms a benign meningioma or other non-malignant neoplasm affecting the spinal dura, arachnoid, or pia mater. This diagnosis is often established through imaging studies (e.g., MRI) and sometimes confirmed by biopsy.

• Differentiate carefully between benign and malignant spinal meningeal neoplasms; malignant cases would be coded differently.
• Ensure the documentation specifies "spinal" meninges, as intracranial meningeal neoplasms have distinct codes.
• Consider additional codes for any neurological deficits or symptoms caused by the tumor (e.g., pain, weakness, sensory disturbances).
