2026 ICD-10-CM Diagnosis Code F19.94 – Other psychoactive substance use, unspecified with psychoactive substance-induced mood disorder
What it is
This code identifies mood symptoms caused by use of an unspecified psychoactive substance. Use it when the record links the mood disorder directly to substance use, but the substance is not named.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include depressed mood, irritability, anxiety, or mood lability occurring in the context of substance use.
When to use this code
Use this code when the provider documents a psychoactive substance-induced mood disorder and does not specify the substance. It is appropriate when the mood disturbance is attributed to substance use, intoxication, withdrawal, or ongoing use. Confirm that the relationship is stated in the record.
Do not use for
Do not use this code if the mood disorder is primary or unrelated to substance use. Check documentation if the substance is specified or if another substance-induced mental disorder is documented instead.
Coding tip
Verify both the mood disorder and the causal link to substance use before assigning F19.94.
