Poisoning by anti-common cold drugs

This code signifies an adverse reaction or overdose resulting from the ingestion or exposure to medications intended to treat common cold symptoms. This includes a broad range of over-the-counter and prescription drugs such as decongestants, antihistamines, cough suppressants, and expectorants, when taken in toxic amounts or causing an unintended harmful effect. The poisoning can be accidental or intentional.

Utilize this code when documentation clearly indicates a patient presented with signs and symptoms of poisoning directly attributable to anti-common cold preparations. This applies to cases of accidental overdose, intentional self-harm, or adverse drug reactions where the drug's toxic effects are the primary concern. Supporting documentation should specify the drug class involved and the nature of the poisoning.

• Always code the specific substance (E-code) in addition to this diagnosis code to identify the drug responsible for the poisoning.
• Distinguish between poisoning (adverse effect due to overdose or wrong substance) and adverse effect in therapeutic use (correct substance, correct dose, but unexpected reaction).
• Consider an additional code for the manifestation of the poisoning (e.g., cardiac arrhythmias, central nervous system depression) if applicable.
