ICD-10 Code B52.8 – Plasmodium malariae malaria with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B52.8 – Plasmodium malariae malaria with other complications
What it is
This code identifies malaria caused by Plasmodium malariae when the record documents additional complications not captured by more specific B52 subcodes. Use it for confirmed P. malariae infection with an associated complication.
Clinical signs
Clinical features vary; refer to documentation. Typical malaria findings may include fever, chills, headache, malaise, and other signs of systemic illness, along with the documented complication.
When to use this code
Use B52.8 when the provider clearly documents Plasmodium malariae malaria plus another complication and no more specific code applies. This supports cases where the complication is present but not separately classified elsewhere. Check documentation for the exact complication and organism.
Do not use for
Do not use this code if the malaria species is different, or if the record does not confirm Plasmodium malariae. Do not assign it when a more specific B52 code describes the documented complication.
Coding tip
Code the organism and the complication exactly as documented; if the complication is unclear, check documentation before assigning B52.8.
