Diseases of the musculoskeletal system and connective tissue - M00-M99
Diseases of the Musculoskeletal System and Connective Tissue - This chapter covers musculoskeletal disorders like arthritis, osteoporosis, and soft tissue injuries.
Chapter notes often provide a brief overview or description of the conditions and diseases covered within that specific chapter. This helps users understand the scope and content of the chapter.
Chapter Notes:
- Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition
Excludes2: This note means that the conditions described by two codes are not usually associated with each other but can sometimes occur together.
Type 2 Excludes:
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
