Sedatv/hyp/anxiolytc use, unsp w persisting dementia

This code signifies a patient experiencing dementia that is directly attributable to the chronic use of sedative, hypnotic, or anxiolytic substances, where the specific substance used is not documented. The cognitive impairment is persistent and not merely an acute intoxication effect.

Apply this code when documentation clearly links a patient's persistent dementia to the long-term use of sedatives, hypnotics, or anxiolytics, and the specific drug class (e.g., benzodiazepine, barbiturate) is not specified. This diagnosis requires a physician's assessment confirming the drug-induced etiology and the chronic nature of the cognitive decline.

• Ensure documentation explicitly states "persisting dementia" and links it to sedative, hypnotic, or anxiolytic use.
• Do not use this code if the specific substance class is known; instead, use a more specific F13.xx7 code.
• This code should be sequenced as a primary diagnosis when the drug-induced dementia is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
