Poisoning by antimycobac drugs, accidental, init

This code signifies an accidental overdose or adverse reaction to medications specifically designed to treat mycobacterial infections, such as tuberculosis or leprosy. The patient unintentionally ingested or was administered an excessive amount of the drug, leading to toxic effects.

Apply this code when documenting an initial encounter for a patient presenting with symptoms of poisoning due to an antimycobacterial drug, where the ingestion or administration was unintentional. This includes cases of accidental double-dosing, medication errors, or a child ingesting a parent's medication.

• Ensure the documentation clearly states the poisoning was accidental and not intentional self-harm.
• Confirm this is the initial encounter for the poisoning event; subsequent care would use a different encounter character.
• Always code the specific antimycobacterial drug if known, using an additional code from T36-T50.
