B17.0

Acute hepatitis B with delta-agent

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 B17.0 is a billable code used to indicate a diagnosis of acute hepatitis b with delta-agent.

Key Diagnostic Point:

Acute hepatitis B with delta-agent is a viral infection of the liver caused by the hepatitis B virus (HBV) in conjunction with the hepatitis D virus (HDV), which is a defective virus that requires HBV for its replication. This condition typically presents with symptoms such as jaundice, fatigue, abdominal pain, and elevated liver enzymes. The delta agent can exacerbate the severity of hepatitis B, leading to a higher risk of acute liver failure and chronic liver disease. Transmission occurs primarily through blood and bodily fluids, including sexual contact and sharing of needles. Acute hepatitis B with delta-agent can lead to serious complications, including fulminant hepatitis, cirrhosis, and hepatocellular carcinoma. Management involves supportive care, monitoring liver function, and in some cases, antiviral therapy. Understanding the interplay between HBV and HDV is crucial for effective treatment and management of the disease.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Co-infection with hepatitis D complicates diagnosis and treatment.
  • Requires understanding of both HBV and HDV transmission routes.
  • Management may involve multiple specialties (infectious disease, hepatology).
  • Differentiating acute from chronic hepatitis can be challenging.

Audit Risk Factors

  • Inadequate documentation of co-infection.
  • Failure to specify acute versus chronic status.
  • Misclassification of hepatitis type.
  • Lack of supporting lab results.

Specialty Focus

Medical Specialties

Infectious Disease

Documentation Requirements

Detailed history of exposure, lab results confirming HBV and HDV co-infection.

Common Clinical Scenarios

Patients presenting with jaundice and elevated liver enzymes after known exposure.

Billing Considerations

Ensure documentation reflects the acute nature and co-infection status.

Hepatology

Documentation Requirements

Liver function tests, imaging studies, and treatment plans.

Common Clinical Scenarios

Management of patients with acute liver failure due to co-infection.

Billing Considerations

Focus on liver biopsy results and long-term management strategies.

Coding Guidelines

Inclusion Criteria

Use B17.0 When
  • According to ICD
  • 10 guidelines, B17
  • 0 should be used when both HBV and HDV are present and the condition is acute
  • Documentation must support the diagnosis with lab results indicating the presence of both viruses

Exclusion Criteria

Do NOT use B17.0 When
  • Exclusion criteria include cases where only HBV or HDV is present without the other

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of hepatitis conditions, including the ability to capture co-infections like HBV and HDV. This specificity aids in better tracking of disease prevalence and management outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of hepatitis conditions, including the ability to capture co-infections like HBV and HDV. This specificity aids in better tracking of disease prevalence and management outcomes.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of hepatitis conditions, including the ability to capture co-infections like HBV and HDV. This specificity aids in better tracking of disease prevalence and management outcomes.
