Poisoning by antiasthmatics, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to an intentional overdose of medication used to treat asthma or other respiratory conditions. The poisoning was a deliberate act of self-harm, and the current encounter is for ongoing management, monitoring, or treatment of the sequelae.

Apply this code when documenting subsequent visits for patients who previously attempted suicide or self-harm by ingesting antiasthmatic drugs. This includes appointments for psychiatric evaluation, ongoing medical treatment of organ damage, or follow-up for complications arising from the initial poisoning event.

• Always use a secondary code for the specific antiasthmatic drug involved, if known.
• Ensure documentation clearly indicates the "subsequent encounter" status, such as follow-up, aftercare, or healing phase.
• Do not use for the initial acute poisoning event; that requires an "A" (initial encounter) seventh character.
