ICD-10 Code D33.4 – Benign neoplasm of spinal cord (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D33.4 – Benign neoplasm of spinal cord
What it is
D33.4 identifies a noncancerous tumor arising from the spinal cord. It indicates a benign neoplasm that is localized to the cord itself, not the surrounding meninges or vertebral structures.
Clinical signs
Clinical features vary; refer to documentation. Patients may have progressive neurologic deficits such as weakness, sensory changes, gait disturbance, or pain from spinal cord compression.
When to use this code
Use D33.4 when the provider documents a benign tumor of the spinal cord and confirms the site as the cord. It is appropriate for pathology, imaging, or operative documentation that clearly identifies a benign spinal cord neoplasm. If the record only says “spinal tumor,” check documentation.
Do not use for
Do not use this code for malignant spinal cord tumors, metastatic disease, or neoplasms of the meninges, nerve roots, or vertebral column. If the lesion type or site is unclear, check documentation.
Coding tip
Verify both benign behavior and exact anatomic site before assigning D33.4.
