Substance abuse codes in the "Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition" include F10.10 and F10.20 for alcohol use disorder, depending on symptoms present, and F15.929 for caffeine intoxication, states Clinical Tools, Inc. Other substance abuse codes include F18.10 and F18.20 for inhalant use disorder, depending on symptoms.
The DSM-5 was released in May 2013, and it established significant changes to the code system for substance abuse disorders as compared to the DSM-IV, according to Clinical Tools, Inc. DSM-5 combines dependence and abuse diagnoses into one diagnosis of substance use disorder. The variation within the specific codes includes sub-codes that depend on comorbidities and the symptoms present. For example, opioid use disorder has two codes, F11.10 and F11.20, and a patient's diagnosis depends on the symptoms present. On the other hand, opioid intoxication is broken down into two subcategories of diagnoses: one that addresses intoxication without perceptual disturbances, containing codes F11.129, F11.229 and F11.929, and the other with perceptual disturbances, encompassing F11.122, F11.222 and F11.922.
The different codes within such subcategory codes of substance intoxication refer to whether or not the condition is comorbid with a substance use disorder and to what extent, states Clinical Tools, Inc. The diagnostic codes for such substance intoxication conditions were not broken up into subcategories in DSM-IV, which is another significant change in DSM-5.
