ICD-10 Code F13.18 – Sedative, hypnotic or anxiolytic abuse with other sedative, hypnotic or anxiolytic-induced disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.18 – Sedative, hypnotic or anxiolytic abuse with other sedative, hypnotic or anxiolytic-induced disorders
What it is
This code identifies abuse of sedative, hypnotic, or anxiolytic drugs when the patient also has another substance-induced disorder from the same class. Use it when documentation links both the abuse pattern and the additional induced condition.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see misuse of prescribed or nonprescribed sedatives with a documented induced disorder such as mood, anxiety, sleep, or other behavioral changes.
When to use this code
Use F13.18 when the record states sedative, hypnotic, or anxiolytic abuse and also documents another sedative-related induced disorder. The provider should connect the two conditions, or the note should clearly support that relationship. Check documentation if the induced disorder is not specified.
Do not use for
Do not use this code for simple use, dependence, or intoxication without abuse. Do not apply it when the induced disorder is from another substance class or when the chart does not support abuse.
Coding tip
Verify that both abuse and the other induced disorder are documented by the provider before assigning F13.18.
