L24.B3 vs L30.9
L24.B3 (Irritant contact dermatitis related to fecal or urinary stoma or fistula) compared with L30.9 (Dermatitis, 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. L24.B3 carries an Excludes1 note covering L30.9: “dermatitis NOS (L30.9)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
