Code Description

ICD-10 F12.99 is a billable code used to indicate a diagnosis of cannabis use, unspecified with unspecified cannabis-induced disorder.

Key Diagnostic Point:

F12.99 refers to a diagnosis of cannabis use that is unspecified, accompanied by an unspecified cannabis-induced disorder. This code is utilized when a patient exhibits symptoms related to cannabis use but does not fit neatly into more specific categories of cannabis-related disorders. Cannabis use can lead to various psychological and physical effects, including intoxication, withdrawal symptoms, and potential development of substance use disorders. Patients may present with issues such as anxiety, mood disturbances, or cognitive impairments that are directly linked to their cannabis consumption. The diagnosis is often made based on patient history, self-reported use, and clinical observations. Treatment may involve counseling, behavioral therapies, and support groups, focusing on reducing cannabis use and addressing any co-occurring mental health issues. Accurate coding is essential for appropriate treatment planning and insurance reimbursement, as well as for tracking public health trends related to substance use.
