ICD-10 Code F16.29 – Hallucinogen dependence with unspecified hallucinogen-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.29 – Hallucinogen dependence with unspecified hallucinogen-induced disorder
What it is
This code identifies a dependence syndrome involving hallucinogen use, with an unspecified disorder caused by the hallucinogen. Use it when the record shows dependence but does not name the induced mental or physical condition.
Clinical signs
Typical findings include compulsive use, tolerance, withdrawal, or continued use despite harm. Clinical features vary; refer to documentation for the specific hallucinogen-induced disorder.
When to use this code
Use this code when the clinician documents hallucinogen dependence and also notes an induced disorder, but does not specify whether it is psychotic, mood-related, anxiety-related, or another type. It is appropriate when the chart supports dependence and the induced condition remains unspecified.
Do not use for
Do not use this code if dependence is not documented or if the record specifies a different hallucinogen-induced disorder. Check documentation when the substance is not a hallucinogen.
Coding tip
Confirm both dependence and an unspecified hallucinogen-induced disorder are documented before assigning F16.29.
