Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- malignant carcinoid tumors (C7A.0-)
- malignant neoplasm of adrenal gland (C74.-)
- malignant neoplasm of endocrine pancreas (C25.4)
- malignant neoplasm of islets of Langerhans (C25.4)
- malignant neoplasm of ovary (C56.-)
- malignant neoplasm of testis (C62.-)
- malignant neoplasm of thymus (C37)
- malignant neoplasm of thyroid gland (C73)
- malignant neuroendocrine tumors (C7A.-)
Risk adjustment
C75 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
