L25.5 vs L50.9
L25.5 (Unspecified contact dermatitis due to plants, except food) compared with L50.9 (Urticaria, unspecified), 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. L25.5 carries an Excludes1 note covering L50.9: “nettle rash (L50.9)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
