B85.2 Pediculosis, unspecified

Name of the Condition

• Pediculosis, unspecified

Summary

Pediculosis, unspecified is a parasitic infestation caused by lice, small wingless insects that feed on human blood. This code is used when the specific type of lice (head, body, or pubic) is not documented. Infestations typically present with itching and may involve visible lice or nits (lice eggs) on the affected area. The condition is highly contagious and spreads through direct contact or shared personal items.

Causes

The infestation is caused by lice, which are parasitic insects. Transmission occurs through close personal contact, sharing of combs, hats, clothing, or bedding, or sexual contact (for pubic lice). Lice cannot jump or fly but crawl between hosts. The specific type of lice is not identified in this unspecified code.

Risk Factors

• Close contact with an infested individual, such as in households, schools, or daycare settings.
• Sharing personal items like combs, brushes, hats, or bedding.
• Sexual activity, which increases the risk of pubic lice transmission.
• Crowded living conditions or poor hygiene (more commonly associated with body lice).

Symptoms

• Intense itching at the site of infestation.
• Visible lice or nits (lice eggs) on the scalp, body, or pubic area.
• Irritation or redness of the skin.

Diagnosis

Diagnosis is typically made through visual inspection of the affected area to identify lice or nits. Healthcare providers may use a magnifying glass or comb to detect the parasites. In some cases, a sample may be collected and examined under a microscope to confirm the presence of lice. The specific type of lice is not determined in this unspecified code.

Treatment Options

Treatment involves the use of pediculicidal agents, such as topical shampoos, lotions, or creams, to kill lice and nits. Over-the-counter or prescription medications may be recommended. It is also important to treat close contacts and thoroughly clean or launder personal items to prevent reinfestation.

Prognosis and Follow-Up

With proper treatment, the prognosis is generally good, and infestations can be resolved. Follow-up may be necessary to ensure complete eradication of lice and nits. Recurrence is possible if reinfestation occurs or if treatment is incomplete.

Complications

Complications may include secondary bacterial infections from scratching, which can lead to skin infections. In severe cases, anemia may occur due to blood loss from body lice infestations.

Lifestyle & Prevention

• Avoid sharing personal items like combs, hats, or clothing.
• Maintain good hygiene and regularly wash bedding and clothing.
• Conduct regular checks for lice, especially in close-contact settings like schools or daycare.
• Treat infested individuals and their close contacts simultaneously to prevent spread.

When to Seek Professional Help

Seek medical attention if itching persists despite treatment, if there are signs of skin infection (e.g., redness, swelling, pus), or if the infestation is severe or widespread.

Tips for Medical Coders

When coding for pediculosis, unspecified (B85.2), ensure the documentation supports the lack of specificity regarding the type of lice. If the type is identified, use the appropriate more specific code. Document the absence of details to justify the use of this unspecified code.
