Instructional NotesGuidance

Excludes1

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

From D13.3 Benign neoplasm of other and unspecified parts of small intestine applies to 2 codes
  • benign carcinoid tumors of the small intestine (D3A.01-)
  • benign neoplasm of ileocecal valve (D12.0)
From D13 Benign neoplasm of other and ill-defined parts of digestive system applies to 11 codes
  • 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).

Patient EducationClinical

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.

What is the ICD-10 code for benign neoplasm of other parts of small intestine?

The ICD-10-CM code for benign neoplasm of other parts of small intestine is D13.39 (sometimes written as D1339). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is D13.39 a billable code?

Not as a rule. The Excludes1 note at D13.3, which applies to D13.39, lists "benign carcinoid tumors of the small intestine (D3A.01-)". 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).

What is the ICD-9 equivalent of D13.39?

Under the General Equivalence Mappings, benign neoplasm of other parts of small intestine converts to ICD-9-CM 211.2 (benign neoplasm sm bowel). The mapping is approximate, so confirm the match fits the documentation.
