Other psychoactive substance dependence, in remission

This code signifies a patient's current state of physiological and psychological dependence on a psychoactive substance (excluding alcohol, opioids, cannabis, sedatives/hypnotics, cocaine, and other stimulants) that is currently in remission. Remission indicates that the patient no longer meets the full criteria for dependence, or has not used the substance for a sustained period, but still carries the history of dependence.

Apply this code when documentation indicates a patient has a history of dependence on a psychoactive substance not specified by other F1x.2x codes, and is currently in a period of remission. This is appropriate for patients who have completed treatment and are maintaining sobriety, or those who have spontaneously ceased use and are stable. Supporting documentation should clearly state the substance type (e.g., hallucinogens, inhalants, multiple drug use) and the current remission status.

• Always specify the exact psychoactive substance if known, using more specific F1x.21 codes when available (e.g., F13.21 for sedative dependence).
• Distinguish between "in remission" and "in use" (F19.20) or "with intoxication" (F19.22x).
• Code any associated physical or mental health conditions related to the substance use disorder.
