CHB ICD-10-CM Codes

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
