Poisoning by antiasthmatics, accidental, subs

This code signifies an accidental overdose or adverse reaction to medication used to treat asthma or other respiratory conditions, occurring during the recovery phase of the poisoning. The patient is no longer in the acute phase of the poisoning but is still receiving care related to its effects.

Apply this code when documenting follow-up care for a patient who previously experienced an unintentional poisoning from an antiasthmatic drug. This includes visits for monitoring lingering side effects, managing complications that arose from the overdose, or adjusting ongoing treatment plans related to the poisoning event.

• Ensure the encounter is for follow-up care, not the initial treatment of the poisoning.
• Always sequence this code after the primary diagnosis for the specific effects of the poisoning.
• Verify that the poisoning was accidental and involved an antiasthmatic agent.
