Other psychoactive substance use, unspecified, in remission

This code indicates a patient has a history of problematic use of a psychoactive substance (other than alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, stimulants, hallucinogens, or inhalants) but is currently in a period of sustained remission. Remission implies that the individual no longer meets the full diagnostic criteria for the substance use disorder.

Use this code when documentation clearly states a diagnosis of "other psychoactive substance use disorder" and specifies that the patient is currently in remission. This applies to substances not categorized elsewhere, such as phencyclidine (PCP) or volatile solvents. Supporting documentation should detail the substance type and confirm the remission status.

• Ensure the specific psychoactive substance is not classifiable under more specific F10-F16 or F18 codes.
• Documentation must explicitly state "in remission" for this specific remission code to be appropriate.
• Do not use if the patient is actively using the substance or experiencing acute withdrawal/intoxication.
