Oth psychoactive substance dependence w oth disorder

This code signifies a patient's physiological and psychological dependence on an unspecified psychoactive substance, accompanied by an additional, specific mental or behavioral disorder directly induced by the substance. This induced disorder could include conditions like psychosis, mood disorders, anxiety disorders, or delirium, beyond simple intoxication or withdrawal.

Apply this code when documentation clearly indicates dependence on a psychoactive substance not otherwise specified (e.g., "polysubstance dependence" or "unspecified substance dependence") and a co-occurring, substance-induced mental health condition. The induced disorder must be explicitly linked to the substance use, and not merely a pre-existing or co-occurring independent mental health condition.

• Ensure documentation specifies both dependence and a distinct, substance-induced disorder, not just intoxication or withdrawal.
• Avoid using this code if a more specific psychoactive substance (e.g., opioid, cannabis) is identified; use the appropriate F11-F16 or F18 code instead.
• Sequence this code as the primary diagnosis when the substance dependence and its induced disorder are the focus of the encounter.
