Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to D20.0: its own notes plus those printed at D20 and 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.
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).

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.

Questions About D20.0Overview
What is the ICD-10 code for benign neoplasm of soft tissue of retroperitoneum?
The ICD-10-CM code for benign neoplasm of soft tissue of retroperitoneum is D20.0 (sometimes written as D200). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is D20.0 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of soft tissue of retroperitoneum on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does D20.0 group to?
When benign neoplasm of soft tissue of retroperitoneum is the principal diagnosis on an inpatient stay, it groups to MS-DRG 394, 395, 393, with relative weights from 0.6379 to 1.5877 depending on complications. Higher weights mean higher Medicare reimbursement.
Can D20.0 be reported with D17.79?
Not as a rule. The Excludes1 note at D20, which applies to D20.0, lists "benign lipomatous neoplasm of peritoneum and retroperitoneum (D17.79)". 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 D20.0?
Under the General Equivalence Mappings, benign neoplasm of soft tissue of retroperitoneum converts to ICD-9-CM 211.8 (ben neo peritoneum). The mapping is approximate, so confirm the match fits the documentation.
