Poisoning by barbiturates

This code signifies an adverse health effect resulting from the ingestion, inhalation, or absorption of barbiturate medications. It encompasses both accidental and intentional overdoses, as well as adverse reactions to therapeutic doses. The poisoning can manifest with central nervous system depression, respiratory depression, hypotension, and potentially coma or death.

Apply this code when documentation clearly indicates a patient's condition is due to poisoning by any barbiturate drug. This includes acute intoxication, toxic effects, or adverse effects of barbiturates. Supporting documentation should specify the barbiturate involved and the resulting clinical manifestations.

• Always code the specific barbiturate if known (e.g., phenobarbital, secobarbital) using an E-code for external cause.
• Distinguish between poisoning (adverse effect, overdose) and therapeutic use with adverse reaction (which might require an E-code for adverse effect in therapeutic use).
• Sequence this code as the principal diagnosis when the poisoning is the primary reason for the encounter.
