ICD-10 Code F17.20 – Nicotine dependence, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F17.20 – Nicotine dependence, unspecified
What it is
F17.20 identifies nicotine dependence when the record does not specify the tobacco product or form. Use it for documented nicotine addiction without a more precise subtype.
Clinical signs
Common findings include craving, difficulty cutting down, and continued use despite harm. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents nicotine dependence but does not name cigarettes, chewing tobacco, or another specific product. It also fits when the chart states dependence is present and no further detail is available. Check documentation before selecting a more specific F17.- code.
Do not use for
Do not use F17.20 for nicotine poisoning, tobacco use without dependence, or dependence on a specified tobacco product when that detail is documented. Do not guess a product type.
Coding tip
If the note says only “nicotine dependence,” code the unspecified form unless the record supports a more specific tobacco-related code.
