About B53

B53 is the ICD-10-CM diagnosis code for other specified malaria. It belongs to block B50-B64 (protozoal diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: B53.0 (malaria), B53.1 (plasmodia) and B53.8 (classified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
