D13 is a non-billable ICD-10-CM category code for benign neoplasm of other and ill-defined parts of digestive system, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D13.0, D13.1, D13.2, and D13.30.

Specific Coding for Benign neoplasm of and ill-defined parts of digestive systemOverview

Non-specific codes like D13 require more characters. Use one of these billable codes instead:

  • Use D13.0 for Benign neoplasm of esophagus

  • Use D13.1 for Benign neoplasm of stomach

  • Use D13.2 for Benign neoplasm of duodenum

  • D13.3 for Benign neoplasm of other and unspecified parts of small intestine

  • Use D13.30 for Benign neoplasm of unspecified part of small intestine

  • Use D13.39 for Benign neoplasm of other parts of small intestine

  • Use D13.4 for Benign neoplasm of liver

  • Use D13.5 for Benign neoplasm of extrahepatic bile ducts

  • Use D13.6 for Benign neoplasm of pancreas

  • Use D13.7 for Benign neoplasm of endocrine pancreas

  • D13.9 for Benign neoplasm of ill-defined sites within the digestive system

  • Use D13.91 for Familial adenomatous polyposis

  • Use D13.99 for Benign neoplasm of ill-defined sites within the digestive system

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D13: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • benign stromal tumors of digestive system (D21.4)

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).

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D13Overview

What is the ICD-10 code for benign neoplasm of other and ill-defined parts of digestive system?

D13 is the ICD-10-CM category for benign neoplasm of other and ill-defined parts of digestive system, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D13 a billable code?

No. This is a category header that groups the codes for benign neoplasm of other and ill-defined parts of digestive system, and headers cannot be submitted on claims. Claims for benign neoplasm of other and ill-defined parts of digestive system need a more specific code from this category, such as D13.0, D13.1, and D13.2.

Can D13 be reported with D21.4?

Not as a rule. The Excludes1 note on D13 lists "benign stromal tumors of digestive system (D21.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
