About C75
C75 is the ICD-10-CM diagnosis code for malignant neoplasm of other endocrine glands and related structures. It belongs to block C73-C75 (malignant neoplasms of thyroid and other endocrine glands) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: C75.0 (gland), C75.1 (gland), C75.2 (duct), C75.3 (gland), C75.4 (body), C75.5 (paraganglia), C75.8 (unspecified) and C75.9 (unspecified).
Don't report C75 together with the conditions in its Excludes1 note: 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) and 5 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
