Diphtheritic radiculomyelitis

This code describes inflammation of the spinal nerve roots and spinal cord due to diphtheria. It represents a neurological complication arising from infection with Corynebacterium diphtheriae, specifically affecting the peripheral and central nervous system components.

Use this code when documentation clearly indicates radiculomyelitis as a direct consequence of diphtheria. This typically follows a confirmed diphtheria diagnosis and presents with symptoms such as muscle weakness, sensory disturbances, and paralysis affecting multiple nerve roots. Supporting documentation should include a confirmed diphtheria infection and neurological findings consistent with radiculomyelitis.

• Always sequence the diphtheria infection code (A36.x) first, followed by this code.
• Ensure documentation specifies "radiculomyelitis" and links it directly to diphtheria, not just general neurological complications.
• Distinguish from other neurological sequelae of diphtheria, such as polyneuropathy (G61.0), which has a separate code.
