L54 vs L71
L54 (Erythema in diseases classified elsewhere) compared with L71 (Rosacea), 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. L54 carries an Excludes1 note covering L71: “rosacea (L71.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
