Poisoning by antimycobacterial drugs, self-harm, sequela

This code signifies a patient presenting with long-term effects or complications resulting from a deliberate overdose or self-poisoning with antimycobacterial medications. These sequelae can manifest in various organ systems, depending on the specific drug and the severity of the initial poisoning.

Apply this code when documenting chronic conditions, organ damage, or other lasting health problems directly attributable to a past intentional self-harm event involving antimycobacterial drugs. This is typically used in follow-up encounters after the acute poisoning has been treated.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic liver failure).
• Ensure documentation clearly links the current condition to the past intentional antimycobacterial drug poisoning.
• The "S" in the 7th character indicates sequela, meaning the residual effects of a past injury or illness.
