Poisoning by antiasthmatics

This code signifies an adverse reaction or overdose resulting from the improper use or ingestion of medications intended to treat asthma. It encompasses both accidental and intentional poisonings by bronchodilators, corticosteroids, and other antiasthmatic agents. The patient is experiencing toxic effects from these substances.

Use this code when documentation clearly indicates a patient's signs and symptoms are directly attributable to an overdose or poisoning by an antiasthmatic drug. This includes scenarios like accidental ingestion by a child, therapeutic misadventure leading to toxicity, or intentional self-harm. The medical record should detail the specific antiasthmatic agent involved and the resulting clinical presentation.

• Always code the specific manifestation of the poisoning first, if applicable (e.g., cardiac arrhythmias, seizures).
• Requires an E-code (E850.0-E858.9 for accidental, E950.0-E950.9 for intentional, E980.0-E980.9 for undetermined) to identify the external cause and intent.
• Distinguish from adverse effects of properly administered drugs (which would typically use codes from the 995.2x series).
