2025 ICD-10-CM code C7B.01
(Active) Effective Date: N/A Neoplasms - Secondary neuroendocrine tumors Chapter 2: Neoplasms Feed
Secondary carcinoid tumors of distant lymph nodes.
Medical necessity is established by the diagnosis of metastatic carcinoid tumor to distant lymph nodes, confirmed by appropriate diagnostic testing. Treatment is medically necessary to control the spread of the disease and manage symptoms.
The provider diagnoses the condition based on history, symptoms, physical examination, biopsy, and imaging tests (X-rays, CT scans, MRI, PET). Treatment may involve chemotherapy, radiation therapy, hormone therapy, and/or surgery.

In simple words: This code indicates that cancer cells from a carcinoid tumor, a type of slow-growing cancer, have spread to lymph nodes far from the original tumor.
Secondary carcinoid tumors of distant lymph nodes refer to the metastasis (spread) of cancer cells from a primary carcinoid tumor site to lymph nodes at a distant location.A carcinoid tumor is a type of neuroendocrine tumor (NET).
Example 1: A patient with a history of carcinoid tumor of the appendix presents with enlarged lymph nodes in the neck. Biopsy confirms metastatic carcinoid tumor., A patient undergoing surveillance for a previously treated lung carcinoid tumor is found to have new lesions in mediastinal lymph nodes., A patient with a small bowel carcinoid tumor develops abdominal pain and distension. Imaging reveals multiple enlarged mesenteric lymph nodes, subsequently confirmed as metastatic carcinoid tumor.
Documentation should include the primary site of the carcinoid tumor, the location of the distant lymph nodes involved, confirmation of metastasis (e.g., biopsy results), and any associated functional activity.
** It's important to distinguish between distant and regional lymph node involvement.If the affected lymph nodes are regional to the primary tumor site, a different code would be used.
