B37.6 vs I39
B37.6 (Candidal endocarditis) compared with I39 (Endocarditis and heart valve disorders in diseases classified elsewhere), 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. I39 carries an Excludes1 note covering B37.6: “candidiasis (B37.6)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
