B52.8 ICD-10-CM Code: Plasmodium malariae malaria with other complications

B52.8 is the ICD-10-CM diagnosis code for plasmodium malariae malaria with other complications. This is a type of malaria infection caused by the Plasmodium malariae parasite that has developed additional serious health complications beyond the basic infection. The complications can affect various body systems and require careful documentation to ensure proper treatment and monitoring. B52.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering protozoal diseases (b50-b64).

B52.8 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.

Always document the specific complications present (such as acute kidney injury, severe anemia, or cerebral involvement) in addition to this code, as the 'other complications' designation requires clarification in the medical record.
