ICD-10 Code F19.93 – Other psychoactive substance use, unspecified with withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.93 – Other psychoactive substance use, unspecified with withdrawal
What it is
This code identifies withdrawal symptoms due to use of another psychoactive substance when the specific substance is not named. Use it when documentation confirms withdrawal, but the drug category is not more precisely identified.
Clinical signs
Clinical features vary; refer to documentation. Typical withdrawal findings may include anxiety, agitation, sleep disturbance, tremor, or other autonomic symptoms after stopping the substance.
When to use this code
Use F19.93 when the record states psychoactive substance withdrawal and the substance is documented only as “other” or remains unspecified. It fits cases where the clinician links current symptoms to withdrawal from a non-alcohol, non-tobacco substance. If the exact substance is later identified, code more specifically.
Do not use for
Do not use this code for intoxication, dependence without withdrawal, or withdrawal from a specifically identified substance that has its own code. Check documentation if the record does not clearly state withdrawal.
Coding tip
Confirm both the withdrawal state and the unspecified substance category before assigning F19.93.
