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.
B18.2 - 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.
B18.9 - Chronic viral hepatitis, unspecified: This code is used when the exact type of chronic viral hepatitis is not specified. It's important to note that various viruses can cause chronic viral hepatitis, including hepatitis B (HBV), hepatitis C (HCV), and others. Sometimes, the exact viral cause might not be definitively determined at diagnosis due to multiple reasons, such as incomplete testing.
Which Chronic Hepatitis B ICD codes are Billable?
The following ICD-10-CM codes for Chronic Hepatitis B are billable:
B18.1 - Yes, billable: Chronic viral hepatitis B without delta-agent is eligible for reimbursement when accurately coded.
B18.2 - Yes, billable: Chronic viral hepatitis B with delta-agent can be billed when documented accurately.
B18.9 - Yes, billable: Unspecified chronic viral hepatitis can be reimbursed when the specific type is not documented.
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:
- Chronic HBV Infection
- Long-term Hepatitis B
- Persistent Hepatitis B

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.
