C75 vs C7A
C75 (Malignant neoplasm of other endocrine glands and related structures) compared with C7A (Malignant neuroendocrine tumors), 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. C75 carries an Excludes1 note covering C7A: “malignant neuroendocrine tumors (C7A.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
