Sedatv/hyp/anxiolytc use, unsp w withdrawal delirium

This diagnosis code indicates a patient experiencing delirium as a result of withdrawal from unspecified sedative, hypnotic, or anxiolytic substances. The patient exhibits acute cognitive impairment, disorientation, and altered consciousness due to the cessation or reduction of these medications. The specific substance causing the withdrawal is not documented or is unknown.

Apply this code when documentation clearly states withdrawal delirium from a sedative, hypnotic, or anxiolytic, but the specific substance is not identified. This is appropriate for acute inpatient or emergency department settings where the immediate cause of delirium is recognized as substance withdrawal. Ensure the medical record explicitly mentions "withdrawal delirium" and "sedative," "hypnotic," or "anxiolytic" use.

• Do not use this code if the specific sedative, hypnotic, or anxiolytic substance is known; instead, use a more specific code from the F13.23- or F13.93- series.
• Always sequence this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
• Ensure documentation differentiates withdrawal delirium from other forms of delirium (e.g., F05 for delirium not otherwise specified) or other substance-induced mental disorders.
