The ICD-10-CM code for malaria is B54 — Unspecified malaria. This is the code the Alphabetic Index gives for malaria with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

BillableUnspecified

B54 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.

Which malaria code should you use?

The Alphabetic Index lists 16 codes under Malaria, malarial. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
