2026 ICD-10-CM Diagnosis Code F55.1 – Abuse of herbal or folk remedies
What it is
F55.1 identifies harmful or excessive use of herbal or folk remedies without evidence of a substance use disorder. Use it when the record shows inappropriate reliance on nonprescribed remedies that is causing concern or harm.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe repeated use, overuse, or dependence on traditional remedies, with possible adverse effects or interference with recommended care.
When to use this code
Use this code when the provider documents abuse, misuse, or excessive use of herbal or folk remedies. It may apply when the remedies are taken in a way that is clearly harmful, persistent, or replacing needed medical treatment.
Code it only when the behavior is specifically documented. If the record is unclear about intent or impact, check documentation before assigning F55.1.
Do not use for
Do not use F55.1 for routine, appropriate use of supplements or traditional remedies. Do not use it when the issue is poisoning, adverse effect, or another better-defined diagnosis.
Coding tip
Look for explicit provider wording such as “abuse” or “misuse” before assigning F55.1.
