Diseases of the Musculoskeletal System and Connective Tissue CHAPTER 18 Diseases of the Musculoskeletal System and Connective Tissue
Diseases of the Musculoskeletal System and Connective Tissue—Code Range M00-M99 Diseases of the musculoskeletal system and connective tissue are reported from Chapter 13 of ICD-10-CM. This chapter contains codes for diseases of the musculoskeletal system and connective tissues. Injuries are classified to Chapter 19 of ICD-10-CM.

Dentofacial Anomalies and Other Disorders of Jaw—M26-M27 This block of code also reports malocclusion. Disorders reported here include: Major anomalies of jaw size Anomalies of dental arch and tooth position Dentofacial functional abnormalities Developmental disorders of jaws Cysts of jaw Dental implant failures
Systemic Connective Tissue Disorders—M30-M36 This block of codes includes autoimmune disease, collagen disease, systemic autoimmune disease, and systemic collagen disease. This block of codes exclude autoimmune disease, single organ, or single cell-type. Coders should be guided by instructional notation that appears at the start of the block of codes.
