Other benign neoplasms of connective and other soft tissue
Non-billable header
D21 is a non-billable header code. Use one of the more specific codes below.
Inclusion terms
Includes
- benign neoplasm of blood vessel
- benign neoplasm of bursa
- benign neoplasm of cartilage
- benign neoplasm of fascia
- benign neoplasm of fat
- benign neoplasm of ligament, except uterine
- benign neoplasm of lymphatic channel
- benign neoplasm of muscle
- benign neoplasm of synovia
- benign neoplasm of tendon (sheath)
- benign stromal tumors
- Note: Functional activity
- Note: 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.
- Note: Morphology [Histology]
- Note: 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.
- Note: Primary malignant neoplasms overlapping site boundaries
- Note: 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.
- Note: Malignant neoplasm of ectopic tissue
- Note: 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).
