B52.8 — Plasmodium malariae malaria with other complications
B52.8 is a billable, specific ICD-10-CM code for plasmodium malariae malaria with other complications. It is valid for submission on a claim.
Excludes1 inherited from the categories above B52.8
These are not written on B52.8, but they bind it: a note on a category applies to every code beneath it. Billing B52.8 with anything listed here is a denial.
Other codes that can never be billed with B52.8
These codes carry an Excludes1 note pointing at B52.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B52.8 alone.
Risk adjustment
B52.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How B52.8 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to B52.8.
