Poisoning by other sedatives and hypnotics

This code signifies an adverse event resulting from the ingestion of or exposure to sedatives and hypnotics not classified elsewhere. It covers both accidental and intentional poisonings, leading to toxic effects on the body. This includes substances like barbiturates, benzodiazepines, and other non-barbiturate sedatives when not specified by a more precise code.

Apply this code when documentation clearly indicates poisoning by a sedative or hypnotic agent that does not have a more specific ICD-9-CM code. This is appropriate for overdose situations, adverse drug reactions manifesting as toxicity, or accidental ingestion. Supporting documentation should specify the substance class and the resulting clinical effects.

• Always attempt to identify the specific sedative or hypnotic agent for a more precise code, if available.
• Distinguish between poisoning (toxic effect) and adverse effect (therapeutic dose).
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for manifestations of the poisoning.
