Code Description

ICD-10 F18.2 is a billable code used to indicate a diagnosis of inhalant dependence.

Key Diagnostic Point:

Inhalant dependence is characterized by a compulsive pattern of inhalant use leading to significant impairment or distress. Inhalants are volatile substances that produce chemical vapors, which can be inhaled to induce psychoactive effects. Common inhalants include solvents, aerosols, and gases found in household products. Dependence on inhalants can manifest through a range of symptoms, including cravings, tolerance, and withdrawal symptoms when not using the substance. Withdrawal may present with symptoms such as irritability, anxiety, sleep disturbances, and physical symptoms like tremors. The condition is often associated with various psychosocial issues, including behavioral problems, academic difficulties, and social isolation. Treatment typically involves behavioral therapies, counseling, and support groups, as there are no specific pharmacological treatments approved for inhalant dependence. Early intervention is crucial to prevent long-term health consequences, including neurological damage and other serious health issues.
