Poisoning by antiasthmatics, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning using antiasthmatic medications. It indicates that the patient intentionally overdosed on drugs designed to treat asthma, and they are now presenting for care related to the lasting consequences of that event. This could include organ damage, neurological deficits, or other chronic conditions directly attributable to the past poisoning.

Use this code when documenting follow-up care for a patient who previously attempted suicide or intentionally harmed themselves by ingesting an overdose of antiasthmatic drugs, and is now experiencing persistent health issues as a direct result. This code is appropriate for encounters addressing the chronic complications or sequelae of such an event, occurring after the acute phase of the poisoning has passed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to the past intentional self-harm by antiasthmatics.
• Do not use this code for the initial acute poisoning event; instead, use the acute poisoning code with the appropriate seventh character.
