C44.1 vs C69
C44.1 (Other and unspecified malignant neoplasm of skin of eyelid, including canthus) compared with C69 (Malignant 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. C69 carries an Excludes1 note covering C44.1: “malignant neoplasm of eyelid (skin) (C43.1-, C44.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
