Oth psychoactv substance abuse w persist amnestic disorder

This code signifies a pattern of problematic use of a psychoactive substance (other than alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, cocaine, or stimulants) leading to clinically significant impairment or distress, specifically complicated by a persistent memory disturbance directly induced by the substance. The amnestic disorder involves significant impairment in the ability to learn new information or recall previously learned information.

Apply this code when documentation clearly indicates abuse of an unspecified psychoactive substance, and the patient presents with a chronic, substance-induced amnestic disorder. This diagnosis requires a direct causal link between the substance abuse and the persisting memory deficits, with the memory impairment not better explained by another mental or neurological disorder.

• Requires documentation specifying "abuse" rather than "dependence" or "use."
• Ensure the specific psychoactive substance is not one with a more specific F1x.1x code (e.g., F10.16 for alcohol, F11.16 for opioid).
• Always sequence this code as the primary diagnosis when the substance abuse and its amnestic sequela are the focus of the encounter.
