Specific Coding for Benign neoplasm of colon, rectum, anus and anal canalOverview

Non-specific codes like D12 require more characters. Use one of these billable codes instead:

  • Use D12.0 for Benign neoplasm of cecum

  • Use D12.1 for Benign neoplasm of appendix

  • Use D12.2 for Benign neoplasm of ascending colon

  • Use D12.3 for Benign neoplasm of transverse colon

  • Use D12.4 for Benign neoplasm of descending colon

  • Use D12.5 for Benign neoplasm of sigmoid colon

  • Use D12.6 for Benign neoplasm of colon, unspecified

  • Use D12.7 for Benign neoplasm of rectosigmoid junction

  • Use D12.8 for Benign neoplasm of rectum

  • Use D12.9 for Benign neoplasm of anus and anal canal

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D12: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

  • benign carcinoid tumors of the large intestine and rectum (D3A.02-)
  • polyp of colon NOS (K63.5)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • 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).
