B97.35 Human immunodeficiency virus, type 2 [HIV 2] as the cause of diseases classified elsewhere

Name of the Condition

• Common Name: HIV-2 as the cause of diseases
• Medical Term: Human Immunodeficiency Virus, Type 2 [HIV 2] as the cause of diseases classified elsewhere

Summary

HIV-2 is a type of human immunodeficiency virus that can lead to immune system impairment. This ICD code specifically recognizes HIV-2 when it contributes to other diseases. While HIV-1 is more common worldwide, HIV-2 is predominantly found in West Africa and has a slower disease progression.

Causes

HIV-2 is caused by a viral infection transmitted through blood, sexual contact, or from mother to child during childbirth or breastfeeding. It weakens the immune system by attacking CD4 cells.

Risk Factors

• Geographic location (prevalent in West Africa)
• Unprotected sexual contact with an infected person
• Sharing needles or exposure to infected blood
• Being born to an HIV-2-positive mother

Symptoms

• Weight loss
• Fatigue
• Swollen lymph nodes
• Fever or night sweats
• Increased susceptibility to opportunistic infections

Diagnosis

• Blood tests to detect HIV antibodies or RNA
• CD4 cell count to assess immune system health
• Viral load tests to measure the amount of virus in the blood

Treatment Options

• Antiretroviral therapy (ART) to control viral load and protect the immune system
• Regular monitoring of CD4 counts and viral loads
• Treatment of opportunistic infections

Prognosis and Follow-Up

• With effective ART, individuals can have a near-normal life expectancy.
• Ongoing follow-up is essential to monitor viral load, adjust treatment, and manage complications.

Complications

• Opportunistic infections due to immune suppression
• Increased risk of certain cancers
• Progressive damage to the body's organs and systems

Lifestyle & Prevention

• Practice safe sex, including condom use.
• Avoid sharing needles and other drug paraphernalia.
• Regular testing and treatment if at risk.

When to Seek Professional Help

• If experiencing symptoms of HIV or after potential exposure to the virus
• Unexplained fevers, weight loss, or persistent infections

Additional Resources

• World Health Organization (WHO)
• Centers for Disease Control and Prevention (CDC)
• Local HIV/AIDS support organizations

Tips for Medical Coders

• Ensure all related conditions are documented to justify the ICD code B97.35.
• Double-check the documentation for the type of HIV to differentiate between HIV-1 and HIV-2.
• Avoid common coding errors by ensuring the code is used only when HIV-2 contributes to other diseases.
