B00.1 vs H62.4
B00.1 (Herpesviral vesicular dermatitis) compared with H62.4 (Otitis externa in other 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. H62.4 carries an Excludes1 note covering B00.1: “herpes viral [herpes simplex] (B00.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
