D3A.02Benign carcinoid tumors of the appendix, large intestine, and rectum

D3A.02 is the ICD-10-CM diagnosis code for benign carcinoid tumors of the appendix, large intestine, and rectum. It belongs to category D3A (benign neuroendocrine tumors), block D3A (benign neuroendocrine tumors) 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.

Within D3A.0 (benign carcinoid tumors), D3A.02 is specifically for benign carcinoid tumors of the appendix, large intestine, and rectum. Related codes cover tumor of unspecified site (D3A.00), of the small intestine (D3A.01) and of other sites (D3A.09).

To report this condition, pick the subcode that matches the documentation: D3A.020 (appendix), D3A.021 (cecum), D3A.022 (colon), D3A.023 (colon), D3A.024 (colon), D3A.025 (colon), D3A.026 (rectum) and D3A.029 (portion).

Use an additional code to identify any associated endocrine syndrome, such as: carcinoid syndrome (E34.00).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
