Secondary carcinoid tumors of liver

This code signifies the presence of metastatic neuroendocrine tumors, specifically carcinoid, that have spread to the liver from a primary site elsewhere in the body. These tumors originate from neuroendocrine cells and, when metastatic to the liver, can cause a range of symptoms depending on hormone secretion and tumor burden.

Use this code when documentation explicitly states "secondary carcinoid tumors of liver" or "metastatic carcinoid to liver." This diagnosis is typically confirmed through imaging (e.g., CT, MRI, Octreoscan) and/or biopsy. It should be used in conjunction with a code for the primary carcinoid tumor.

• Always sequence the primary carcinoid tumor code before this secondary site code.
• Do not use this code for primary neuroendocrine tumors originating in the liver; those have different code assignments.
• Ensure the documentation clearly distinguishes between primary and secondary liver involvement.
