B53.0

B53.0 — Plasmodium ovale malaria

Billable / specific codeICD-10-CM

B53.0 is a billable, specific ICD-10-CM code for plasmodium ovale malaria. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Plasmodium ovale with Plasmodium falciparum (B50.-)
Plasmodium ovale with Plasmodium malariae (B52.-)
Plasmodium ovale with Plasmodium vivax (B51.-)

Other codes that can never be billed with B53.0

These codes carry an Excludes1 note pointing at B53.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B53.0 alone.

B53.1Malaria due to simian plasmodia

Risk adjustment

B53.0 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 B53.0 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 B53.0.
