About the F16 Code Range
The ICD-10 code section F16 is used to classify disorders related to hallucinogen use, including abuse, dependence, intoxication, and their associated mental health conditions. These codes help specify whether the hallucinogen-related disorder is uncomplicated, in remission, or accompanied by additional symptoms such as mood or psychotic disorders.
This section covers a range of conditions under hallucinogen-related disorders, including terms like hallucinogen abuse, phencyclidine (PCP) abuse, and hallucinogen dependence. Codes such as F16.10 identify uncomplicated abuse, while F16.11 indicates remission. More detailed codes classify intoxication symptoms, including delirium and perceptual disturbances. Additionally, hallucinogen-induced mood and psychotic disorders, such as delusions and hallucinations, are addressed with specific subcodes like F16.15 and F16.25. The code range also accounts for less common issues including anxiety disorders, persistent perception disorder (flashbacks), and unspecified or other specified hallucinogen-induced disorders. This detailed classification assists medical coders and healthcare providers in accurately documenting the type and severity of hallucinogen-related conditions for effective treatment and reporting.
