ICD-10 Code F16.188 – Hallucinogen abuse with other hallucinogen-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.188 – Hallucinogen abuse with other hallucinogen-induced disorder
What it is
This code identifies hallucinogen abuse when the patient also has another disorder caused by hallucinogen use. It applies when the record supports misuse and a separate hallucinogen-induced condition, but not a more specific code.
Clinical signs
Clinical features vary; refer to documentation. You may see behavioral changes, impaired judgment, or symptoms tied to the induced disorder, such as mood, anxiety, or perceptual disturbances.
When to use this code
Use this code when the provider documents hallucinogen abuse and an additional hallucinogen-induced disorder, and the record does not name a more specific subtype. It is appropriate when the induced condition is clinically linked to hallucinogen use. Check documentation for the exact disorder and substance.
Do not use for
Do not use this code for simple hallucinogen use without abuse, dependence, or an induced disorder. Also avoid it when documentation supports a more specific hallucinogen-related diagnosis.
Coding tip
Code the substance use and the induced condition from the provider’s wording, and verify whether the record supports a more specific hallucinogen code.
