Poisoning by sympathomimetics [adrenergics]

This code signifies an adverse health event resulting from the toxic effects of sympathomimetic agents, also known as adrenergics. This includes both accidental and intentional overdose or misuse of substances that mimic the effects of the sympathetic nervous system, such as amphetamines, ephedrine, or pseudoephedrine. The poisoning can manifest with symptoms like tachycardia, hypertension, agitation, and seizures.

Assign this code when a patient presents with signs and symptoms of toxicity directly attributable to sympathomimetic drugs. This applies to cases of acute overdose, adverse reactions to therapeutic doses, or recreational drug use leading to poisoning. Documentation should clearly state the substance involved and the resulting toxic effects.

• Always identify the specific sympathomimetic agent if known, using an E-code for external cause of poisoning.
• Distinguish between poisoning (toxic effect) and adverse effect (unintended but expected reaction to proper drug use).
• Consider sequencing this code as the primary diagnosis when the poisoning is the reason for the encounter, followed by codes for specific manifestations.
