Poisoning by mixed sedatives, not elsewhere classified

This code signifies an adverse effect resulting from the ingestion or exposure to multiple sedative medications, where the specific combination is not individually classified elsewhere. It indicates a toxic reaction or overdose involving a mixture of drugs intended to induce sleep or reduce anxiety. The patient presents with symptoms consistent with sedative poisoning, such as central nervous system depression.

Apply this code when documentation clearly states poisoning by a combination of sedatives, and no more specific ICD-9-CM code exists for the particular mixture. This is appropriate for cases of accidental overdose, intentional self-harm, or adverse drug reactions involving multiple sedative agents. Supporting documentation should detail the substances involved, even if not specifically named in the code description, and confirm the toxic effect.

• Always review documentation for specific sedative agents involved; if a more specific combination code exists, use that instead.
• This code requires an external cause code (E-code) to specify the circumstances of the poisoning (e.g., accidental, intentional).
• Do not use for poisoning by a single sedative agent, even if the specific drug is not listed elsewhere; look for codes for poisoning by specific classes of sedatives.
