Clinical Classification Guidelines
Medical Intelligence & Overview
Cervical intervertebral disc infection, classified under ICD-10 code M46.32, is a rare but serious condition involving the infection of the discs located between the cervical vertebrae in the neck. This pyogenic (pus-forming) infection can cause significant neck pain, neurological issues, and structural damage if not diagnosed and treated promptly. It typically results from bacterial invasion into the disc space, leading to inflammation, abscess formation, and, potentially, spinal instability.

Iatrogenic causes, such as infections following surgical procedures or invasive spinal interventions. Trauma to the neck, which can facilitate bacterial entry.

Key Symptoms: Severe pain in the neck that worsens with movement. Stiffness or reduced range of motion in the neck. Fever, chills, or general feeling of illness. Localized swelling or tenderness over the affected cervical area. Neurological symptoms such as numbness, tingling, weakness, or radiating pain in the arms or hands. Signs of systemic infection, including fatigue or malaise.
