ICD-10 Code F14.921 – Cocaine use, unspecified with intoxication delirium (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F14.921 – Cocaine use, unspecified with intoxication delirium
What it is
Use this code for cocaine use, unspecified, when the patient has intoxication delirium. It indicates a delirious state caused by cocaine intoxication, with the substance use type not further specified.
Clinical signs
Typical findings include acute confusion, reduced awareness, disorganized thinking, and fluctuating attention during cocaine intoxication. Clinical features vary; refer to documentation.
When to use this code
Assign this code when the record documents cocaine use with intoxication delirium and does not identify a more specific cocaine-related diagnosis. Use it for encounters where delirium is attributed to cocaine intoxication, not withdrawal or another substance.
If the chart names a different cocaine use disorder severity or a separate mental status condition, check documentation before coding. Do not assume delirium unless the provider clearly links it to intoxication.
Do not use for
Do not use this code for cocaine withdrawal, cocaine-induced psychotic disorder, or unspecified cocaine use without delirium. Check documentation if the record does not clearly state intoxication delirium.
Coding tip
Code the substance and the delirium relationship exactly as documented; if the provider does not specify intoxication delirium, query or check documentation.
