About the B52 Code Range
The ICD-10 code B52 identifies malaria caused by the parasite Plasmodium malariae, including its variations and related complications. These codes are used to classify and document cases ranging from uncomplicated infection to serious kidney involvement or other complications.
This section includes the primary code B52 for Plasmodium malariae malaria, often called "quartan malaria" or "quartan fever" in clinical contexts. The code B52.0 is specifically for malaria with nephropathy, indicating kidney damage due to the infection, sometimes referred to as disorders of the glomerulus caused by the parasite. For cases with additional complications such as malarial pigment deposits, B52.8 is used. When the infection occurs without any complications, coders rely on B52.9. These distinctions help accurately capture the severity and manifestations of Plasmodium malariae malaria for both treatment records and epidemiological tracking. Understanding these long-tail terms, like "malarial red blood cell inclusion" or "Plasmodium malariae gametocyte," helps ensure the correct ICD-10 code is assigned for patient care and reporting.
