ICD Code B19.20

ICD code B19.20 is used to classify cases of unspecified viral hepatitis C where the patient does not experience hepatic coma. This code is applied when the specific type of hepatitis C virus is not identified, but it is clear that the condition does not involve the severe complication of hepatic coma, which is a state of unconsciousness resulting from liver failure. This code is essential for accurate medical documentation and billing, ensuring that healthcare providers can track and manage cases of hepatitis C effectively without the added complexity of hepatic coma.

1. Positive Serological Test for Hepatitis C Virus (HCV): The patient must have a confirmed positive test for the presence of the hepatitis C virus, indicating an active or past infection.

2. Absence of Hepatic Coma: The patient should not exhibit symptoms of hepatic coma, which includes confusion, altered level of consciousness, or other signs of severe liver dysfunction leading to brain impairment.

3. Liver Function Tests: Abnormal liver function tests (LFTs) such as elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, which suggest liver inflammation or damage, should be present.

4. Absence of Specific Symptoms of Other Hepatitis Types: The patient should not exhibit symptoms or have test results that specifically indicate other types of viral hepatitis, such as hepatitis A or B.

5. Chronic or Acute Presentation: The diagnosis can be made regardless of whether the hepatitis C infection is acute or chronic, as long as it is unspecified in terms of severity or duration.

6. Exclusion of Other Liver Diseases: Other potential causes of liver disease, such as alcoholic liver disease or non-alcoholic fatty liver disease, should be ruled out to ensure the symptoms are attributable to hepatitis C.

7. Clinical Evaluation: A comprehensive clinical evaluation should be conducted to assess symptoms such as fatigue, jaundice, abdominal pain, or other signs that may be associated with hepatitis C infection.

8. Patient History: A detailed patient history should be reviewed, including any known risk factors for hepatitis C, such as intravenous drug use, blood transfusions before 1992, or other potential exposures to the virus.

For the ICD code B19.20, which pertains to unspecified viral hepatitis C without hepatic coma, the relevant CPT codes that may be applicable for treatment and management include:

1. CPT 99201-99215: These codes cover evaluation and management services provided in an office or other outpatient setting. The specific code within this range would depend on the complexity and time spent on the patient encounter.

2. CPT 80076: This code is used for a hepatic function panel, which is a common laboratory test to assess liver function in patients with hepatitis C.

3. CPT 87522: This code is used for hepatitis C virus (HCV) quantification, a necessary test to determine the viral load in patients diagnosed with hepatitis C.

4. CPT 86803: This code is for hepatitis C antibody testing, which is often used to confirm the presence of the virus.

5. CPT 99241-99245: These codes are for office or other outpatient consultations, which may be necessary for further evaluation and management of the condition.

6. CPT 99401-99404: These codes are for preventive medicine counseling, which may be relevant for lifestyle modifications and education related to hepatitis C management.

7. CPT 96365-96368: These codes cover intravenous infusion for therapy, prophylaxis, or diagnosis, which may be applicable if antiviral therapy is administered intravenously.

The selection of specific CPT codes will depend on the individual patient's treatment plan, the services provided, and the healthcare provider's documentation. Always ensure that coding is aligned with the latest guidelines and payer requirements.
