A06 vs B52
A06 (Amebiasis) compared with B52 (Plasmodium malariae malaria), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. B52 carries an Excludes1 note covering A06: “amebiasis (A06.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
