ICD-10 Code F16.24 – Hallucinogen dependence with hallucinogen-induced mood disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.24 – Hallucinogen dependence with hallucinogen-induced mood disorder
What it is
This code identifies a hallucinogen use disorder with dependence, along with a mood disorder caused by hallucinogen use. Use it when documentation links the mood change directly to the substance.
Clinical signs
Clinical features vary; refer to documentation. You may see dependence features plus depressive or manic symptoms that the clinician attributes to hallucinogen use, rather than a primary mood disorder.
When to use this code
Use this code when the record states hallucinogen dependence and specifies an induced mood disorder, such as substance-related depression or mood disturbance. It fits encounters where the provider clearly connects both conditions. Check documentation if the mood diagnosis is not explicitly substance-induced.
Do not use for
Do not use this code for hallucinogen use without dependence, or for a primary mood disorder unrelated to substance use. If the mood condition is unspecified or the substance link is unclear, check documentation.
Coding tip
Confirm that both dependence and the hallucinogen-induced mood disorder are documented before assigning F16.24.
