D22.1 vs D31
D22.1 (Melanocytic nevi of eyelid, including canthus) compared with D31 (Benign neoplasm of eye and adnexa), 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. D31 carries an Excludes1 note covering D22.1: “benign neoplasm of skin of eyelid (D22.1-, D23.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
