Opioid use, unspecified, in remission

This code signifies a historical diagnosis of opioid use disorder where the individual is currently in a period of sustained remission. It indicates that the patient no longer meets the diagnostic criteria for active opioid use disorder, but the history of the condition is clinically relevant.

Apply this code when documentation clearly states a history of opioid use disorder and the patient is currently in remission, without specifying the severity or pattern of use. This is appropriate for follow-up visits or when the historical diagnosis is pertinent to current care, such as for medication management or ongoing therapy.

• Ensure documentation explicitly states "in remission" for opioid use. Avoid using this code for active opioid use or withdrawal.
• Do not use this code if the type of opioid is specified (e.g., heroin, fentanyl); instead, use a more specific code from the F11.2- category with the appropriate remission subclassification.
• Consider sequencing this code after any acute conditions or primary reasons for the encounter, as it often represents a historical or chronic condition impacting overall health.
