L27.2 vs T62
L27.2 (Dermatitis due to ingested food) compared with T62 (Toxic effect of other noxious substances eaten as food), 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. T62 carries an Excludes1 note covering L27.2: “dermatitis (L23.6, L25.4, L27.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
