Poisoning by antimycobacterial drugs, self-harm, subs

This code signifies a patient presenting with adverse effects or complications resulting from intentionally self-inflicted poisoning by antimycobacterial medications. The "subsequent encounter" indicates that this is not the initial visit for the poisoning, but rather a follow-up for ongoing care, monitoring, or treatment of the sequelae.

Apply this code when documenting a patient's visit for follow-up care after a deliberate overdose of drugs used to treat tuberculosis or other mycobacterial infections. This includes scenarios where the patient is being monitored for organ damage, psychiatric evaluation, or managing persistent symptoms related to the self-harm event.

• Ensure documentation clearly states intentional self-harm as the cause of poisoning.
• Confirm this is a subsequent encounter; for the initial encounter, use the appropriate "A" seventh character.
• Always code with an external cause code (e.g., X61.0X-, X61.1X-) to fully describe the circumstances of the poisoning.
