L68.0 Hirsutism

Name of the Condition

• Hirsutism

Summary

Hirsutism is a medical condition characterized by excessive hair growth in a male pattern in women, typically affecting areas such as the face, chest, and back. It results from increased androgen levels or heightened sensitivity to androgens. The condition is distinct from hypertrichosis, which involves generalized excessive hair growth in non-androgen-dependent areas.

Causes

Hirsutism is commonly caused by elevated androgen levels, often due to conditions like polycystic ovary syndrome (PCOS), adrenal hyperplasia, or androgen-secreting tumors. Other factors include medications (e.g., anabolic steroids, minoxidil) or idiopathic causes where no underlying disorder is identified.

Risk Factors

• Hormonal imbalances: Conditions like PCOS, Cushing syndrome, or thyroid disorders.
• Family history: Genetic predisposition to androgen excess.
• Obesity: Increased adipose tissue can convert androgens to estrogen, disrupting hormone balance.
• Certain medications: Anabolic steroids, danazol, or glucocorticoids.

Symptoms

• Excessive hair growth on the face (e.g., upper lip, chin), chest, back, or abdomen.
• Hair texture may be coarse and dark, resembling male-pattern hair distribution.
• May be accompanied by other signs of androgen excess, such as acne or menstrual irregularities.

Diagnosis

Diagnosis involves a thorough medical history, physical examination, and laboratory tests to assess androgen levels (e.g., testosterone, DHEA-S) and rule out underlying conditions. Imaging or additional tests may be performed if an androgen-secreting tumor is suspected.

Treatment Options

• Lifestyle modifications: Weight loss and dietary changes to improve hormonal balance.
• Medications: Oral contraceptives, anti-androgens (e.g., spironolactone), or eflornithine cream to reduce hair growth.
• Hair removal: Temporary methods (shaving, waxing) or permanent options (laser therapy, electrolysis).

Prognosis and Follow-Up

Prognosis depends on the underlying cause. With appropriate treatment, hair growth can be managed, but long-term follow-up may be necessary to monitor hormonal levels and adjust therapy. Untreated hirsutism may persist or worsen.

Complications

• Psychological distress due to cosmetic concerns.
• Potential underlying conditions (e.g., PCOS) may lead to additional health issues like infertility or metabolic syndrome.

Lifestyle & Prevention

• Maintain a healthy weight to reduce androgen production.
• Avoid medications known to trigger hirsutism unless medically necessary.
• Use gentle hair removal methods to minimize skin irritation.

When to Seek Professional Help

Consult a healthcare provider if excessive hair growth is sudden, worsening, or accompanied by other symptoms (e.g., menstrual changes, acne, or voice deepening), as these may indicate an underlying hormonal disorder.

Tips for Medical Coders

Document the location and pattern of hair growth, any associated symptoms (e.g., menstrual irregularities), and results of hormonal testing. Ensure differentiation from hypertrichosis and specify if hirsutism is idiopathic or linked to a documented condition. Use additional codes for underlying causes (e.g., PCOS) when applicable.
