    • 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).
Approximate Synonyms
  • Lipoma (clinical)
  • Lipoma (fatty mass)
  • Lipoma of spina bifida
  • Lipoma, spina bifida
Clinical Information
  • A benign (not cancer) tumor made of fat cells.
  • A benign neoplasm composed of adipose tissue.
  • A benign tumor composed of adipose (fatty) tissue. The most common representative of this category is the lipoma.
  • A benign tumor composed of fat cells (adipocytes). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.
  • A benign, usually painless, well-circumscribed lipomatous tumor composed of adipose tissue.
  • Skin biopsy, diagnostic of pss: skin biopsy revealing increased compact collagen in the reticular dermis, thinning of the epidermis, loss of rete pegs, atrophy of dermal appendages, and hyalinization and fibrosis of arterioles.
ICD-10-CM D17.9 is grouped within Diagnostic Related Group(s) (MS-DRG v40.0):
