Diseases of the musculoskeletal system and connective tissue

Covers diseases of the musculoskeletal system and connective tissue, including arthritis, osteoporosis, and dorsopathies. This is one of the more site-and-laterality-intensive chapters.

Key coding points

• •Most codes require specification of laterality (right, left, unspecified) and, where relevant, the specific bone, joint, or region affected.
• •Pathological fractures follow their own encounter-type convention (initial, subsequent, sequela) similar to traumatic fractures in Chapter 19.
