FY2027Chapter 2: Neoplasms/D10–D36 Benign neoplasms, except benign neuroendocrine tumors

Non-billable headerNot valid on its own. Use one of the more specific codes under it.

D21.2 is a non-billable ICD-10-CM code header for benign neoplasm of connective and other soft tissue of lower limb, including hip. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are D21.20 Benign neoplasm of connective and other soft tissue of unspecified lower limb, including hip; D21.21 Benign neoplasm of connective and other soft tissue of right lower limb, including hip and D21.22 Benign neoplasm of connective and other soft tissue of left lower limb, including hip. Its coding notes include 13 Excludes1 entries.

Notes

Also from chapter/block level (8 notes)
Inherited from Chapter 2 Neoplasms
  • 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).
