Sedatv/hyp/anxiolytc dependence w persisting dementia

This code signifies a patient's physiological dependence on sedatives, hypnotics, or anxiolytics, where the chronic use of these substances has directly led to a persistent cognitive decline meeting the criteria for dementia. The dementia is not due to another medical condition or substance, but is a direct and lasting consequence of the drug dependence.

Apply this code when documentation clearly indicates both a current or historical dependence on sedatives, hypnotics, or anxiolytics, and a diagnosed, enduring dementia directly attributed to this substance use. This typically requires a neurological or psychiatric evaluation confirming the substance-induced cognitive impairment.

• Ensure documentation specifies "dependence" and not just "abuse" or "use" to justify the .2 category.
• Confirm the dementia is explicitly linked as "induced by" or "due to" the sedative/hypnotic/anxiolytic use and is persisting.
• Do not code if the dementia is transient or resolves upon cessation of the substance; this code is for persisting dementia.
