Name of the Condition

• Congenital Non-Neoplastic Nevus
• Also known as congenital melanocytic nevus or birthmark.

Summary

• Congenital non-neoplastic nevi are common skin growths present from birth. They consist of clusters of pigmented skin cells and are generally harmless, but may require monitoring for changes.

Causes

• The condition arises from a collection of pigmented cells (melanocytes) during fetal development. It is primarily a genetic occurrence.

Risk Factors

• Genetic predisposition. The exact molecular causes continue to be studied, but individuals with a family history of nevi may be more likely to have them.

Symptoms

• Typically appear as dark, flat, or raised marks on the skin. They vary in size from small to large and can be located anywhere on the body.

Diagnosis

• Diagnosed through physical examination by a healthcare provider.
• Dermatoscopy may be used for closer examination.
• In some cases, a biopsy may be conducted to rule out malignancy if changes in the nevus occur.

Treatment Options

• Most nevi require no treatment.
• Surgical removal might be considered for cosmetic reasons or if there is a concern about potential malignancy.
• Laser therapy may be an option for cosmetic management.

Prognosis and Follow-Up

• Generally benign with an excellent prognosis.
• Regular monitoring is important, especially for large congenital nevi, as there is a small risk of developing melanoma.

Complications

• Potential developing into melanoma, though this is rare.
• Psychological impacts due to cosmetic appearance.

Lifestyle & Prevention

• Regular skin checks for any changes in existing nevi.
• Protection from excessive sun exposure to reduce potential risk of changes.

When to Seek Professional Help

• Any change in size, color, or texture of a nevus.
• Development of symptoms like bleeding, itching, or pain.

Tips for Medical Coders

• Ensure the nevus is congenital and non-neoplastic when coding under ICD Code Q82.5.
• Validate if there is any documentation indicating malignancy or complications as these may necessitate additional coding.
