Chapter 13
Diseases of the musculoskeletal system and connective tissue
M00-M99
This chapter covers the musculoskeletal system and connective tissue, including arthritis, osteoporosis, and dorsopathies, and is one of the more site- and laterality-intensive chapters in ICD-10-CM. Pathological fractures in this chapter follow an encounter-type convention similar to traumatic fractures elsewhere in the classification.
