ICD-10 Code F17.203 – Nicotine dependence unspecified, with withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F17.203 – Nicotine dependence unspecified, with withdrawal
What it is
This code identifies nicotine dependence when the type of tobacco product is not specified and the patient is experiencing withdrawal. It reflects a clinical diagnosis of dependence, not just casual use.
Clinical signs
Withdrawal may include irritability, anxiety, restlessness, trouble concentrating, increased appetite, or strong cravings after reducing or stopping nicotine. Clinical features vary; refer to documentation.
When to use this code
Use F17.203 when the record documents nicotine dependence and withdrawal, but does not specify the tobacco form. You may use it for patients who have stopped or cut down and are noted to have withdrawal symptoms. Confirm that the provider links the symptoms to nicotine withdrawal.
Do not use for
Do not use this code for simple tobacco use without dependence or for withdrawal symptoms not attributed to nicotine. If the tobacco type is specified, check documentation for a more specific code.
Coding tip
Look for explicit documentation of both dependence and withdrawal before assigning this code.
