ICD-10 Code F13.280 – Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced anxiety disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.280 – Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced anxiety disorder
What it is
This code identifies a documented dependence on sedative, hypnotic, or anxiolytic drugs with anxiety symptoms caused by the substance itself. Use it when the anxiety disorder is directly linked to the drug use.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include excessive worry, restlessness, tension, irritability, or panic-like symptoms that begin during intoxication, withdrawal, or ongoing use.
When to use this code
Use this code when the provider states both dependence and a substance-induced anxiety disorder. The record should connect the anxiety to sedative, hypnotic, or anxiolytic use rather than to a primary anxiety disorder.
It may apply in psychiatric or substance-use encounters where the clinician documents medication-related anxiety. Check documentation for the specific substance and the causal relationship.
Do not use for
Do not use this code for uncomplicated dependence without anxiety, or for primary anxiety disorders unrelated to substance use. Check documentation if the record does not clearly identify the drug-induced cause.
Coding tip
Assign the code only when both dependence and substance-induced anxiety are explicitly documented together.
