Poisoning by antimycobacterial drugs, self-harm, init

This diagnosis code signifies a deliberate act of self-poisoning using medications specifically designed to treat mycobacterial infections, such as tuberculosis or leprosy. The patient intentionally ingested or administered an excessive dose of an antimycobacterial agent with the intent to cause harm. This code is assigned during the initial phase of treatment for this acute event.

This code is appropriate for documenting cases where a patient presents to an emergency department or is admitted for an overdose of an antimycobacterial drug, and the medical record clearly indicates the act was intentional self-harm. It should be used for the initial encounter during which the poisoning is evaluated and treated. Subsequent encounters for the same poisoning event would utilize different seventh characters.

• Always confirm the intent of self-harm through physician documentation.
• Ensure the specific drug involved is an antimycobacterial agent.
• Verify this is the initial encounter for the poisoning; subsequent care requires a different seventh character.
