ICD-10 Code F13.21 – Sedative, hypnotic or anxiolytic dependence, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.21 – Sedative, hypnotic or anxiolytic dependence, in remission
What it is
This code identifies a past sedative, hypnotic, or anxiolytic dependence that is currently in remission. Use it when the patient no longer meets criteria for active dependence, but the history remains clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. The record should show prior dependence with current remission, meaning ongoing compulsive use or withdrawal-related dependence is not present.
When to use this code
Use this code when the provider documents sedative, hypnotic, or anxiolytic dependence and states it is in remission. It may apply during follow-up, behavioral health review, or general medical visits when the history affects care planning. Confirm the substance class and remission status in the note.
Do not use for
Do not use this code for active dependence, uncomplicated use, abuse, or intoxication. If the chart does not clearly state remission, check documentation before assigning F13.21.
Coding tip
Code the specific substance-related disorder only when the provider documents dependence in remission, not merely a past use history.
