About the B53 Code Range

The ICD-10 code B53 covers other specified types of malaria that are less common or do not fit into usual categories. This section is used to classify infections caused by particular malaria parasites such as Plasmodium ovale and malaria infections from simian (monkey) plasmodia.

The codes in this category provide precise identification for cases like B53.0, which labels Plasmodium ovale malaria, often referred to as "Ovale malaria." B53.1 is reserved for malaria caused by simian plasmodia, indicating malaria species originating from non-human primates. The code B53.8 captures other malarial infections that don’t fall under the usual classifications such as malaria caused by Plasmodium species other than Plasmodium falciparum. By using these codes properly, healthcare providers and coders can differentiate between types of malaria infections, aiding in accurate diagnosis and tailored treatment. Understanding the ICD-10 code for other specified malaria helps ensure cases with uncommon malaria parasites are documented correctly in medical records.
