Poisoning by expectorants

This code represents an adverse health event resulting from the ingestion, inhalation, or absorption of an expectorant medication in a quantity or manner that causes toxic effects. This includes accidental overdose, intentional self-harm, or therapeutic misadventure leading to poisoning symptoms.

Use this code when documentation clearly indicates a patient is experiencing symptoms of poisoning specifically attributed to an expectorant agent. This typically involves a history of exposure to an expectorant and clinical signs such as nausea, vomiting, dizziness, or more severe systemic effects.

• Always sequence this code as the primary diagnosis when the poisoning is the reason for the encounter.
• Assign an E-code (E850-E869 for accidental, E950-E959 for intentional, E960-E969 for assault, E980-E989 for undetermined) to specify the external cause of the poisoning.
• Do not use this code for adverse effects of correctly administered expectorants; instead, consider codes from the 995.2x series.
