H02.71 Chloasma of eyelid and periocular area

Name of the Condition

• Chloasma of eyelid and periocular area
• Also known as melasma or hyperpigmentation.

Summary

Chloasma is a skin condition marked by dark, discolored patches on the skin. When affecting the eyelid and periocular area, it presents as brownish or grayish spots around the eyes. This condition is often associated with hormonal changes, sun exposure, or genetic factors.

Causes

The exact cause of chloasma is not fully understood, but it is believed to be related to hormonal fluctuations, sun exposure, or genetic predisposition. Pregnancy and oral contraceptive use are common triggers due to hormone changes.

Risk Factors

• Female gender
• Pregnancy (often termed “the mask of pregnancy”)
• Use of oral contraceptives or hormone replacement therapy
• Frequent sun exposure
• Skin phototypes III to V (darker skin tones)
• Family history of melasma

Symptoms

• Brown or grayish-brown patches on the skin
• Irregular patches around the eyelid and surrounding eye area
• The distribution pattern may be symmetrical

Diagnosis

Diagnosis is based on clinical examination by a dermatologist. A Wood's lamp may be used to evaluate pigment changes, and occasionally, a skin biopsy is performed to rule out other conditions.

Treatment Options

• Topical depigmenting agents (e.g., hydroquinone)
• Sun protection using broad-spectrum sunscreens
• Chemical peels and laser therapy for more persistent cases

Prognosis and Follow-Up

Chloasma may persist for months or years, especially if triggers like sun exposure or hormonal changes continue. Regular follow-up with a dermatologist is recommended to monitor changes and adjust treatment as needed.

Complications

• Persistent hyperpigmentation despite treatment
• Emotional or psychological distress due to cosmetic concerns
• Potential recurrence after discontinuing treatment

Lifestyle & Prevention

• Use broad-spectrum sunscreen daily to protect against UV exposure
• Avoid known triggers like hormonal medications if possible
• Wear protective clothing and hats when outdoors
• Maintain a consistent skincare routine

When to Seek Professional Help

Seek medical attention if the patches worsen, spread, or cause significant distress. A healthcare provider can confirm the diagnosis and recommend appropriate treatment options.

Tips for Medical Coders

Document the specific location (eyelid and periocular area) and any contributing factors (e.g., hormonal triggers, sun exposure) to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM code H02.71 for proper classification.
