ICD-10 to ICD-11 Converter / Chapter 13 Chapter 13: Diseases of the Musculoskeletal System and Connective Tissue ICD-10 to ICD-11 crosswalk mappings for codes M00-M99
542 ICD-10 codes in this chapter have ICD-11 crosswalk mappings from the WHO.
Includes back pain, osteoarthritis, rheumatoid arthritis, osteoporosis, gout, disc disorders, tendinitis, and connective tissue diseases like lupus. Low back pain (M54.5) and knee osteoarthritis (M17) are among the most frequently coded conditions in outpatient medicine.
