Begin your search for the right code for a patient’s Neuroendocrine and Carcinoid tumor in the alphabetic index, not the Neoplasm Table..
- Neuroendocrine tumor
Neuroendocrine Tumor | Appropriate ICD code | ICD10 description |
When the documentation states only neuroendocrine tumor and does not provide enough information (type) to assign a more specific code. | D3A.8 | Neuroendocrine tumor NOS |
Malignant poorly differentiated neuroendocrine tumors | C7A.1 | Malignant poorly differentiated neuroendocrine tumors |
When documentation states Malignant neuroendocrine tumor/ Primary malignant neuroendocrine tumor | C7A.8 | Other malignant neuroendocrine tumors |
Secondary neuroendocrine carcinoma | C7B.8 | Other secondary neuroendocrine tumors |
Secondary Merkel cell carcinoma | C7B.1 |
If a neuroendocrine tumor (NET) spreads, it can spread to the below sites and metastasis code should be from C7B series. Carcinoid malignancies aren’t going to metastasize as another type of carcinoma.
- tissues or structures near the organ where the cancer started, such as the peritoneum, the pleura or fat tissue
- lymph nodes around where the cancer started (regional lymph nodes)
- liver
- lungs
- pancreas
- bone
- Carcinoid tumors are one subset of tumors called neuroendocrine tumors, usually begin in the digestive tract (stomach, appendix, small intestine, colon, rectum) or in the lungs.
Carcinoid Tumor Scenario | Appropriate ICD | ICD code Description |
When the documentation states only carcinoid tumor and does not provide enough information (site) to assign a more specific code. | D3A.00 | Carcinoid tumor NOS – unspecified site |
Malignant carcinoid tumor | C7A.00 | Malignant Carcinoid tumor NOS – unspecified site. We have codes between (C7A.010 to C7A.098) |
Secondary carcinoid tumor | C7B.00 | Secondary Carcinoid tumor NOS – unspecified site. We have codes between (C7B.01 to C7B.09) |
