ICD-10 Code F16.28 – Hallucinogen dependence with other hallucinogen-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.28 – Hallucinogen dependence with other hallucinogen-induced disorder
What it is
This code describes a pattern of hallucinogen dependence along with another disorder caused by hallucinogen use. Use it when the record shows both ongoing dependence and an additional hallucinogen-induced condition.
Clinical signs
Clinical features vary; refer to documentation. You may see compulsive use, impaired control, withdrawal concerns, and symptoms linked to the induced disorder, such as persistent perceptual, mood, or behavioral changes.
When to use this code
Use F16.28 when the provider documents hallucinogen dependence and specifies another hallucinogen-induced disorder. It applies when the induced condition is present and is not better captured by a more specific code. Check documentation if the exact induced disorder is unclear.
Do not use for
Do not use this code for hallucinogen use without dependence, or when only intoxication or withdrawal is documented. If the record names a different substance-related disorder, code that condition instead.
Coding tip
Code both dependence and the documented induced disorder only when the provider clearly links them in the record.
