D21 vs D28.2
D21 (Other benign neoplasms of connective and other soft tissue) compared with D28.2 (Benign neoplasm of uterine tubes and ligaments), 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. D21 carries an Excludes1 note covering D28.2: “benign neoplasm of uterine ligament, any (D28.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
