ICD-10 Code F55.3 – Abuse of steroids or hormones (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F55.3 – Abuse of steroids or hormones
What it is
F55.3 identifies nonmedical use of steroids or hormones, such as taking them in a pattern that causes harm or is outside prescribed directions. It applies when the behavior is documented as abuse rather than therapeutic use.
Clinical signs
Clinical features vary; refer to documentation. Records may note misuse, dependence-like behavior, or adverse effects linked to steroid or hormone overuse, but the diagnosis depends on the provider’s stated assessment.
When to use this code
Use F55.3 when the clinician documents abuse of steroids or hormones and the record supports nonmedical or harmful use. Code it for outpatient, inpatient, or behavioral health documentation when the substance is not being used as prescribed. If the note only describes prescribed therapy or an adverse reaction, check documentation before assigning this code.
Do not use for
Do not use this code for routine prescribed hormone therapy, accidental poisoning, or general adverse drug effects. If the chart does not clearly state abuse, check documentation.
Coding tip
Assign F55.3 only when the provider explicitly documents abuse of steroids or hormones.
