L82 Seborrheic keratosis

Name of the Condition

• Seborrheic keratosis

Summary

Seborrheic keratosis is a common, benign skin growth that appears as a brown, black, or tan waxy or scaly patch. It is non-cancerous and typically develops in older adults. These growths are often found on the face, chest, shoulders, or back and may vary in size and number. They are generally harmless but can be cosmetically bothersome.

Causes

The exact cause of seborrheic keratosis is not fully understood, but it is associated with aging and genetic factors. Ultraviolet (UV) light exposure may play a role in their development, though they are not directly caused by sun damage. The condition is not contagious and does not result from infections or poor hygiene.

Risk Factors

• Age: Most common in adults over 50 years.
• Family history: Genetic predisposition may increase risk.
• Sun exposure: Prolonged UV exposure may contribute to development.
• Skin type: More prevalent in individuals with lighter skin tones.

Symptoms

• Raised, waxy, or scaly growths on the skin.
• Color variations, including brown, black, or tan.
• Smooth or rough texture, sometimes with a "stuck-on" appearance.
• No pain or itching unless irritated by clothing or scratching.

Diagnosis

Diagnosis is typically made through a visual examination by a healthcare provider. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions, such as melanoma or warts. Dermoscopy may also be used to examine the growth more closely.

Treatment Options

• Observation: No treatment is necessary if the growth is asymptomatic and cosmetically acceptable.
• Cryotherapy: Freezing the growth with liquid nitrogen to remove it.
• Curettage: Scraping the growth with a surgical instrument.
• Electrosurgery: Using an electric current to burn off the growth.
• Laser therapy: Removing the growth with a laser.

Prognosis and Follow-Up

Seborrheic keratosis is benign and does not pose a health risk. Once removed, it rarely recurs in the same location. Follow-up is generally not required unless new growths appear or existing ones change in appearance, size, or color, which may warrant re-evaluation.

Complications

Complications are rare but may include minor bleeding or infection if the growth is irritated or removed improperly. In rare cases, a growth may be misdiagnosed as a more serious condition, highlighting the importance of accurate diagnosis.

Lifestyle & Prevention

• Protect skin from excessive sun exposure using sunscreen.
• Avoid scratching or picking at growths to prevent irritation.
• Regular skin checks to monitor for changes in existing or new growths.

When to Seek Professional Help

Consult a healthcare provider if a growth changes in size, color, or texture; bleeds; becomes painful; or is accompanied by itching or inflammation. These changes may indicate a need for further evaluation.

Tips for Medical Coders

When coding for seborrheic keratosis, use ICD-10-CM code L82. Documentation should include the location, number, and characteristics of the growths, as well as any treatments performed. Ensure the diagnosis is clearly differentiated from other skin conditions to support accurate coding.
