Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D48.118: its own notes plus those printed at D48.1, D48, block D37-D48, 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.

From D48.1 Neoplasm of uncertain behavior of connective and other soft tissue applies to 11 codes
  • neoplasm of uncertain behavior of articular cartilage (D48.0)
  • neoplasm of uncertain behavior of cartilage of larynx (D38.0)
  • neoplasm of uncertain behavior of cartilage of nose (D38.5)
  • neoplasm of uncertain behavior of connective tissue of breast (D48.6-)
From D48 Neoplasm of uncertain behavior of other and unspecified sites applies to 21 codes
  • neurofibromatosis (nonmalignant) (Q85.0-)
From Block D37-D48 Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes applies to 137 codes
  • neoplasms of unspecified behavior (D49.-)

Notes

General instructions on how these codes are used.

From Block D37-D48 Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes applies to 137 codes
  • Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
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).

Clinical InformationClinical

  • Desmoid Tumors

    locally aggressive tumors that form in the connective tissues of body with no known potential for metastasis. however, they are characterized by an infiltrative growth pattern, allowing invasion into nearby tissues and organs, particularly evident in patients with familial adenomatous polyposis.

Patient EducationClinical

Desmoid tumor

A desmoid tumor is an abnormal growth that arises from connective tissue, which is the tissue that provides strength and flexibility to structures such as bones, ligaments, and muscles. Affected individuals typically develop a single tumor, although some have multiple tumors.

Questions About D48.118Overview

What is the ICD-10 code for desmoid tumor of other site?

The ICD-10-CM code for desmoid tumor of other site is D48.118 (sometimes written as D48118). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is D48.118 (Desmoid tumor) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report desmoid tumor of other site on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does D48.118 group to?

When desmoid tumor of other site is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.

Can D48.118 be reported with D48.0?

Not as a rule. The Excludes1 note at D48.1, which applies to D48.118, lists "neoplasm of uncertain behavior of articular cartilage (D48.0)". 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).
