Reader Question:

List 199.1 for Neurendocrine Carcinoma

Question: What is the diagnosis code for neurendocrine carcinoma? We could find no specific reference in the ICD-9 manual. Previously we used 194.9 (Malignant neoplasm of other endocrine glands and related structures; endocrine gland) and our payer rejected the claim.
