Is B15.0 an HCC code?
No. B15.0 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
B15.0 is the ICD-10-CM diagnosis code for hepatitis a with hepatic coma. Hepatitis A infection with severe liver damage that causes the patient to lose consciousness or become confused due to liver failure. B15.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering viral hepatitis (b15-b19).
B15.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Hepatic coma indicates fulminant hepatic failure; ensure this serious complication is clearly documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B15.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
