Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to D13.7: its own notes plus those printed at D13 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Islet cell tumor
- Benign neoplasm of islets of Langerhans
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code to identify any functional activity.
Notes
General instructions on how these codes are used.
- 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 D13.7Overview
What is the ICD-10 code for benign neoplasm of endocrine pancreas?
The ICD-10-CM code for benign neoplasm of endocrine pancreas is D13.7 (sometimes written as D137). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D13.7 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of endocrine pancreas on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D13.7 group to?
When benign neoplasm of endocrine pancreas is the principal diagnosis on an inpatient stay, it groups to MS-DRG 644, 645, 643, with relative weights from 0.7461 to 1.6138 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D13.7 be reported with D21.4?
Not as a rule. The Excludes1 note at D13, which applies to D13.7, 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).
Does D13.7 need an additional code?
When the condition applies, yes. The Use Additional Code note reads: code to identify any functional activity.. The additional code is reported after D13.7.
