What ICD-10 codes are used for chronic hepatitis B (CHB)?

Chronic hepatitis B (CHB) is a long-term liver infection caused by the hepatitis B virus. Accurate ICD-10-CM codes are essential for medical billing and documentation. Below are the commonly used codes for Chronic hepatitis B:

  • B18.1 - Chronic viral hepatitis B without delta-agent: This code is used for CHB cases without co-infection by the hepatitis D virus. Chronic viral hepatitis B is a condition caused by the hepatitis B virus (HBV) that persists in the body for an extended period, usually over six months. The "delta-agent" refers to the hepatitis D virus (HDV), which can co-infect individuals already infected with HBV and lead to more severe liver disease.
  • B18.0 - Chronic viral hepatitis B with delta-agent: This code is used for CHB cases with co-infection by the hepatitis D virus. Hepatitis D is a unique virus that requires the presence of hepatitis B (HBV) to replicate. HDV infection can occur either as a superinfection in individuals with chronic HBV infection or as a coinfection in those with acute HBV infection. HDV can lead to more severe liver disease compared to HBV infection alone.

Please note that these are for chronic hepatitis B. CHB can easily be mistaken for congenital heart block, congenital malformations, etc. So, if you're looking for an ICD-10-CM code for congenital heart block and related problems (like code Q24.6 for congenital heart block), please check your preferred ICD database for the correct range (congenital malformations, deformations, and chromosomal abnormalities).

Clinical information

  • Chronic hepatitis B (CHB) is a long-term viral infection affecting the liver.
  • It is caused by the hepatitis B virus (HBV) and can lead to liver inflammation and damage.
  • Most CHB cases result from perinatal transmission, sexual contact, or exposure to infected blood.
  • Many people with CHB may not have noticeable symptoms initially.
  • Over time, symptoms can develop, including fatigue, jaundice, abdominal pain, and appetite loss.
  • Diagnosis involves blood tests for HBV antigens, antibodies, and liver function markers.
  • CHB can be categorized into phases based on viral load and liver enzyme levels.
  • Management includes antiviral medications to suppress viral replication and reduce liver damage.
  • Regular monitoring of liver function and viral load is crucial for treatment effectiveness.
  • Vaccination is available to prevent HBV transmission and reduce the risk of CHB development.
  • Individuals with CHB should avoid alcohol, maintain a healthy lifestyle, and adhere to medical recommendations.

Synonyms include

Commonly asked questions

While chronic Hepatitis B is not always curable, antiviral medications can manage it effectively. Early diagnosis and appropriate medical care are crucial to prevent complications.

Diagnosis involves blood tests that detect specific markers of the Hepatitis B virus, including the HBsAg (Hepatitis B surface antigen) and HBV DNA.

Vaccination against Hepatitis B is the primary method of prevention. Practicing safe sex and avoiding sharing needles or personal items that may be contaminated with blood are also necessary preventive measures.
