ICD-10 Code E28.1 – Androgen Excess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E28.1 – Androgen excess
What it is
E28.1 identifies androgen excess, meaning the body has more male-type hormones than expected. Use it when documentation states hyperandrogenism or a similar diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include hirsutism, acne, menstrual irregularity, or virilizing changes when androgen excess is clinically significant.
When to use this code
Use E28.1 when the provider documents androgen excess as the diagnosis or a confirmed cause of hyperandrogenic symptoms. It may apply in endocrine or gynecologic evaluations when the condition is the reason for assessment. Code the documented condition, not isolated symptoms alone.
Do not use for
Do not use this code for nonspecific acne, hair growth, or menstrual problems without documented androgen excess. Check documentation if the record only suggests a possible hormonal imbalance.
Coding tip
Look for explicit provider wording such as “androgen excess” or “hyperandrogenism” before assigning E28.1.
