Malignant neoplasm of bone and articular cartilage of other and unspecified sites (C41)

Browse all the diagnosis codes used for malignant neoplasm of bone and articular cartilage of other and unspecified sites (c41). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Chondrosarcoma - A slowly growing malignant neoplasm derived from cartilage cells, occurring most frequently in pelvic bones or near the ends of long bones, in middle-aged and old people. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion or in patients with ENCHONDROMATOSIS. (Stedman, 25th ed)

Chondrosarcoma, Clear Cell - A chondrosarcoma of adolescence to old age of the proximal EPIPHYSES of long bones. It has variably clear cytoplasm of the mostly neoplastic CHONDROCYTES with little intervening matrix.

Chondrosarcoma, Mesenchymal - A rare aggressive variant of chondrosarcoma, characterized by a biphasic histologic pattern of small compact cells intermixed with islands of cartilaginous matrix. Mesenchymal chondrosarcomas have a predilection for flat bones; long tubular bones are rarely affected. They tend to occur in the younger age group and are highly metastatic. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1456)

Chordoma - A malignant tumor arising from the embryonic remains of the notochord. It is also called chordocarcinoma, chordoepithelioma, and notochordoma. (Dorland, 27th ed)

Enchondromatosis - Benign growths of cartilage in the metaphyses of several bones.
