ICD-10 Code B52.0 – Plasmodium malariae malaria with nephropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B52.0 – Plasmodium malariae malaria with nephropathy
What it is
B52.0 identifies malaria caused by Plasmodium malariae when kidney involvement is documented. Use it when the record links the malaria infection to nephropathy.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe malaria symptoms plus evidence of renal disease or nephropathy associated with the infection.
When to use this code
Use this code when the provider documents Plasmodium malariae malaria with nephropathy, malaria nephropathy, or kidney damage attributed to this parasite. It applies when the renal condition is part of the diagnosis, not merely a coincidental finding. Check documentation if the species or kidney link is unclear.
Do not use for
Do not use B52.0 for malaria caused by another Plasmodium species or for malaria without nephropathy. If nephropathy is documented but the malaria connection is not established, code the conditions separately as supported by the record.
Coding tip
Verify both the species and the renal complication in the provider note before assigning B52.0.
