Sedatv/hyp/anxiolytc use, unsp w intoxication delirium

This code signifies a patient experiencing delirium due to the acute effects of an unspecified sedative, hypnotic, or anxiolytic substance. The patient exhibits altered mental status, disorientation, and cognitive impairment directly attributable to the substance's intoxicating effects. The specific substance causing the intoxication is not documented.

Use this code when documentation clearly indicates delirium as a direct result of sedative, hypnotic, or anxiolytic intoxication, but the specific substance is not identified. This is appropriate for acute care settings where the immediate cause of delirium is substance-related, and further specificity is unavailable. Documentation should explicitly state "intoxication delirium" and link it to this class of substances.

• Ensure documentation specifies "delirium" and not just "intoxication" or "altered mental status."
• Do not use if the specific sedative, hypnotic, or anxiolytic substance is known; instead, use a more specific code from the F13.92- subcategory.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if the delirium complicates another condition.
