Serum neuropathy

This code represents a peripheral neuropathy that develops as a reaction to the administration of a serum, vaccine, or antitoxin. It is characterized by nerve damage, often presenting with pain, weakness, and sensory disturbances, typically occurring days to weeks after exposure to the offending agent. This condition is an immune-mediated response affecting the peripheral nervous system.

Use this code when documentation clearly indicates a diagnosis of neuropathy directly attributed to a serum, vaccine, or antitoxin. This diagnosis is typically supported by a history of recent administration of such agents and the subsequent onset of neurological symptoms consistent with peripheral nerve involvement. Ensure the physician's documentation explicitly links the neuropathy to the serum exposure.

• Always sequence this code first if it is the primary reason for the encounter.
• Do not confuse this with other forms of neuropathy not caused by serum, vaccine, or antitoxin exposure.
• Look for specific documentation of the causative agent, though it is not required for this code itself.
