Is B50.0 an HCC code?

What This Code Means
B50.0 is the ICD-10-CM diagnosis code for plasmodium falciparum malaria with cerebral complications. A severe form of malaria caused by Plasmodium falciparum parasite that has affected the brain, causing neurological complications such as cerebral malaria. B50.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering protozoal diseases (b50-b64).
B50.0 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.
Document specific cerebral complications (seizures, coma, altered mental status) when present.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B50.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document specific cerebral complications (seizures, coma, altered mental status) when present
- •Verify geographic origin or travel history to endemic areas for epidemiological tracking
