D3A.021 - Benign carcinoid tumor of the cecum

ICD-10-CM Chapter 2: Neoplasms · D3A Benign neuroendocrine tumors (D3A) · Subcategory of D3A.02 · FY2027

Includes, Excludes and Coding Notes

Excludes 2 — Not Included HereFrom D3A

Not part of this code; report both codes when the patient has both conditions.

  • benign pancreatic islet cell tumors (D13.7)
Use Additional CodeFrom D3A

Add a secondary code to identify the associated condition or cause when it is documented.

  • code to identify any associated endocrine syndrome, such as:
  • carcinoid syndrome (E34.00)
Code AlsoFrom D3A

Report an additional code when both conditions apply.

  • any associated multiple endocrine neoplasia [MEN] syndromes (E31.2-)
NotesFrom Chapter C00-D49

Instructional notes from the ICD-10-CM tabular list.

  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
