Poisoning by peripheral nerve- and plexus-blocking anesthetics

This code signifies an adverse reaction or overdose specifically due to anesthetics that block nerve impulses in the peripheral nervous system or nerve plexuses. This includes substances like local anesthetics (e.g., lidocaine, bupivacaine) when they cause systemic toxicity or other harmful effects. The poisoning can manifest as cardiovascular, neurological, or respiratory compromise.

Use this code when a patient presents with symptoms of toxicity or adverse effects directly attributable to an overdose or improper administration of a peripheral nerve or plexus-blocking anesthetic. Documentation should clearly state the specific anesthetic agent involved and the resulting signs and symptoms of poisoning. This code is appropriate for accidental overdose, therapeutic misadventure, or intentional self-harm.

• Always code the specific manifestation of the poisoning (e.g., cardiac arrest, seizures) in addition to this code.
• Distinguish this from adverse effects of general anesthetics or other drug classes.
• Review documentation for intent (accidental vs. intentional) and the specific drug class to ensure accurate coding.
