ICD-10 Code F55.2 – Abuse of laxatives (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F55.2 – Abuse of laxatives
What it is
F55.2 identifies misuse of laxatives in a way that is harmful or excessive. Use it when documentation shows nonmedical or inappropriate use of laxative products.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted clues include repeated laxative use, dependence on bowel stimulants, or symptoms linked to overuse such as diarrhea or abdominal discomfort.
When to use this code
Use this code when the provider documents laxative abuse, misuse, or dependence on laxatives. It may apply in eating-disorder contexts or when the record clearly states inappropriate self-administration. Check documentation for intent and substance involved.
Do not use for
Do not use it for routine constipation treatment or normal prescribed laxative use. If the record does not clearly show abuse, check documentation and code the documented condition instead.
Coding tip
Code F55.2 only when the chart explicitly supports laxative abuse; otherwise, use the documented constipation or other underlying diagnosis.
