Poisoning by local anesthetics, accidental, init

This code signifies an accidental or unintentional poisoning specifically due to a local anesthetic agent. It indicates that the patient has experienced adverse effects from the anesthetic, not as an intended therapeutic outcome, but as a result of an error in administration, dosage, or an unexpected reaction.

Use this code when a patient presents with symptoms of toxicity following the administration of a local anesthetic, where the poisoning is determined to be accidental. This could include scenarios such as an overdose during a dental procedure, an unintended intravascular injection, or an allergic-like reaction to the anesthetic itself, occurring during the initial phase of treatment.

• Ensure documentation clearly states the poisoning was accidental and identifies the substance as a local anesthetic.
• Verify that this is the initial encounter for the poisoning; subsequent encounters would require a different seventh character.
• Always code the specific local anesthetic if known, using an additional code from T36-T50, with the appropriate fifth or sixth character for accidental poisoning.
