ICD-10 Code F19.91 – Other psychoactive substance use, unspecified, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.91 – Other psychoactive substance use, unspecified, in remission
What it is
This code identifies a history of other psychoactive substance use disorder that is currently in remission. Use it when the substance category is not otherwise specified and the disorder is no longer active.
Clinical signs
Clinical features vary; refer to documentation. The record should support prior psychoactive substance use disorder and note remission, meaning current criteria for active use disorder are not met.
When to use this code
Use this code when the clinician documents remission from a psychoactive substance use disorder and does not name a more specific substance-related diagnosis. It is appropriate for follow-up visits, history review, or problem lists when the disorder remains clinically relevant.
Confirm that the record clearly states remission rather than active use, intoxication, withdrawal, or dependence. Check documentation if the substance type or remission status is unclear.
Do not use for
Do not use this code for active substance use, intoxication, withdrawal, or uncomplicated history of use without a disorder diagnosis. Do not assign it when a more specific substance or remission code is documented.
Coding tip
Code the most specific substance-related diagnosis available, and verify that “in remission” is explicitly documented before assigning F19.91.
