ICD-9-CM Codes for Intradural Spinal Lesions (Historical)

Note: ICD-9-CM is obsolete (replaced by ICD-10-CM Oct 2015). The following are historical references:

• 336.1 – Other primary brain and nervous system tumor (includes spinal cord neoplasms).
• 225.0 – Benign neoplasm of brain and spinal cord (not skin; original text error).

ICD-10-CM Equivalents

• D32.0–D32.9 – Benign neoplasm of meninges/brain/spinal cord
• D42.0–D42.9 – Neoplasm of uncertain behavior of meninges/brain/spinal cord
• C70.0–C70.9 – Malignant neoplasm of meninges
• C72.0 – Malignant neoplasm of spinal cord

For an intradural L2 mass, current coding requires specification of behavior (benign/uncertain/malignant) and exact site. Neurosurgical/pathology correlation essential.
