ICD-10 Code B19.20: Unspecified viral hepatitis C without hepatic coma
What is this code?
ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes unspecified viral hepatitis. The most accurate code depends on whether the chart identifies hepatitis B, hepatitis C, or whether hepatic coma is documented.
When is it used?
- May be used when a clinician documents unspecified viral hepatitis c without hepatic coma in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code can be used as a clinically usable diagnosis entry in standardized coding workflows.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
đź©şClinical context
- Primary-care, emergency, inpatient, gastroenterology, and infectious-disease workflows where viral hepatitis is part of the active assessment but the final documented type remains incomplete or partially specified.
- Coding and utilization-review workflows where the chart identifies hepatitis B versus hepatitis C or coma status and that detail changes final unspecified-viral-hepatitis code specificity.
- Evaluation often includes liver-enzyme review, hepatitis-serology context, hepatic-encephalopathy or coma assessment when severe illness is present, and follow-up planning for further hepatitis typing or treatment.
- Documentation usually becomes more specific when the chart identifies hepatitis B versus hepatitis C and whether hepatic coma is present.
- Specialist context already linked on this page includes Infectious Disease Specialist, General Physician, Gastroenterologist.
🔍Key distinctions
- This ICD-10 family captures unspecified viral hepatitis patterns rather than chronic-hepatitis coding or fully specified acute hepatitis families.
- Hepatitis type detail and hepatic-coma status are what drive final code specificity inside this unspecified viral-hepatitis family.
- Unspecified viral hepatitis C without hepatic coma is coded separately from unspecified viral hepatitis C with hepatic coma.
- Documentation that describes unspecified viral hepatitis is coded differently depending on whether hepatitis B or C is identified and whether hepatic coma is documented.
