Also known as
Acute hepatitis B
Covers acute hepatitis B infections with or without delta agent.
Chronic viral hepatitis B
Identifies chronic hepatitis B without delta-agent and with no hepatic coma.

Specifies chronic hepatitis B with co-infection by delta-agent, no coma.
Other acute viral hepatitis
May be used for unspecified acute viral hepatitis if B is suspected.
Follow this step-by-step guide to choose the correct ICD-10 code.

Coding acute or chronic Hepatitis B without specifying carrier status or current activity leads to inaccurate severity and payment.
Failing to code Hepatitis D along with Hepatitis B when present impacts quality metrics and patient care planning.
Coding Hepatitis B based on suspected exposure without confirmatory testing can result in inaccurate data reporting and overcoding.
Q: What are the most accurate diagnostic markers for chronic hepatitis B infection in patients with atypical serology?
A: Diagnosing chronic hepatitis B infection (CHB) in patients with atypical serology can be challenging. While HBsAg is typically the hallmark marker, isolated anti-HBc positivity or discordant serological results may require further investigation. The most accurate diagnostic approach involves a combination of assays. Quantitative HBV DNA testing is crucial, as detectable viral load confirms active replication and establishes a diagnosis of CHB, even in the absence of HBsAg. Consider implementing reflex HBV DNA testing in patients with isolated or atypical antibody patterns. Additionally, assessing HBsAg mutants through specific assays can uncover occult HBV infection, particularly in HBsAg-negative individuals with detectable HBV DNA. Explore how combining serological markers with HBV DNA and HBsAg mutant testing ensures accurate diagnosis in complex cases and guides appropriate management strategies. Learn more about the clinical significance of occult HBV infection.
Q: How can I differentiate between active and inactive chronic hepatitis B infection using laboratory values and patient clinical presentation?
A: Differentiating between active and inactive chronic hepatitis B infection is essential for determining appropriate management strategies. Active CHB is characterized by elevated ALT levels, often exceeding the upper limit of normal, indicating ongoing liver inflammation. HBV DNA levels are typically high, reflecting viral replication. Patients might experience symptoms such as fatigue, abdominal discomfort, and jaundice, though many remain asymptomatic. In contrast, inactive CHB or the inactive carrier state demonstrates persistently normal ALT levels for at least one year. HBV DNA levels are typically low or undetectable, indicating minimal viral replication. Patients generally remain asymptomatic. Consider implementing regular monitoring of ALT and HBV DNA levels to distinguish between these phases and guide treatment decisions. Learn more about the latest guidelines for antiviral therapy initiation and monitoring in CHB patients.
Patient presents with signs and symptoms suggestive of Hepatitis B infection. Presenting complaints may include fatigue, jaundice, abdominal pain, nausea, vomiting, dark urine, and clay-colored stools. Physical examination may reveal hepatomegaly and right upper quadrant tenderness. Differential diagnosis includes other viral hepatitis, autoimmune hepatitis, and drug-induced liver injury. Laboratory testing is crucial for diagnosis, including Hepatitis B surface antigen (HBsAg), Hepatitis B surface antibody (HBsAb), Hepatitis B e antigen (HBeAg), Hepatitis B e antibody (HBeAb), and Hepatitis B core antibody (HBcAb). Liver function tests (LFTs), including ALT, AST, alkaline phosphatase, and bilirubin, are elevated, indicative of liver inflammation. Viral load quantification (HBV DNA) is essential for assessing disease activity and treatment response. Diagnosis of chronic Hepatitis B infection is established by the persistence of HBsAg for more than six months. The patient's medical history, social history including risk factors such as intravenous drug use, unprotected sexual contact, and perinatal transmission, and family history are relevant to the diagnosis and management. Treatment options for chronic Hepatitis B include antiviral medications such as tenofovir and entecavir, which aim to suppress viral replication and prevent disease progression to cirrhosis and hepatocellular carcinoma. Patient education regarding transmission prevention, vaccination for household contacts, and regular monitoring are crucial components of management. ICD-10 code B18.0 and B18.1 are applicable depending on the specific manifestation. Referral to a hepatologist or gastroenterologist may be indicated for complex cases or those requiring antiviral therapy. Follow-up appointments are scheduled to monitor liver function, viral load, and treatment response.
