Anal high risk human papillomavirus (HPV) DNA test positive
ICD10CM code
Name of the Condition
- Anal High-Risk Human Papillomavirus (HPV) DNA Test Positive
- ICD-10 Code: R85.81
Summary
High-risk human papillomavirus (HPV) is a group of viruses that can cause cell changes in the anal region, potentially leading to cancer. A positive anal HPV DNA test indicates the presence of these high-risk virus strains, underscoring the need for monitoring and possible further assessment.
Causes
- High-risk HPV strains are primarily spread through sexual contact.
- Persistent infection with these strains can cause cellular changes in the anal region.
Risk Factors
- Engaging in anal sex or having multiple sexual partners.
- Weakened immune system, including HIV infection.
- Smoking and a history of sexually transmitted infections (STIs).
Symptoms
- Often asymptomatic initially.
- May eventually lead to symptoms such as anal warts, bleeding, or changes in bowel habits if associated with cellular changes or malignancy.
Diagnosis
- Anal cytology (Pap test) to detect abnormal cells.
- HPV DNA tests specifically identify high-risk HPV strains.
Treatment Options
- Monitoring with regular follow-up tests in the case of a positive HPV test but no abnormal cells.
- Ablative therapies or surgical removal for treatment of pre-cancerous lesions.
- Vaccination and lifestyle changes to help prevent new infections.
Prognosis and Follow-Up
- Regular monitoring is essential to detect and manage any pre-cancerous changes early.
- Many high-risk HPV infections resolve on their own, but persistence requires continued surveillance.
Complications
- Untreated high-risk HPV infections can lead to anal intraepithelial neoplasia (AIN) and anal cancer.
- Possible psychological stress from the diagnosis and its implications.
Lifestyle & Prevention
- Vaccination against HPV can significantly reduce the risk.
- Safe sexual practices, including condom use, reduce transmission.
- Smoking cessation may reduce HPV persistence.
When to Seek Professional Help
- Persistent anal pain, bleeding, or irregular bowel habits.
- New or changing anal warts or lesions.
Additional Resources
- Centers for Disease Control and Prevention (CDC)
- American Sexual Health Association
- HPV support forums and local clinics for emotional and medical guidance.
Tips for Medical Coders
- Confirm the test purpose and results clearly documented in medical records when using ICD code R85.81.
- Avoid confusion with low-risk HPV detection, which involves different coding and implications for patient management.
