Other disorders of the musculoskeletal system and connective tissue (M95)

ICD-10 code range M95 covers various acquired deformities of the musculoskeletal system and connective tissue, focusing on abnormalities developing after birth. These codes identify specific deformities affecting parts such as the nose, ear, head, neck, chest, pelvis, and other skeletal regions.

The codes in the M95 series are used for documenting conditions like acquired deformity of the nose (including terms like saddle nose and nasal hump), and cauliflower ear, which is a common acquired deformity of the pinna (outer ear). Other codes specify deformities of the head, such as plagiocephaly or acquired malar hypoplasia. Deformities of the neck, chest ribs (including pectus excavatum and barrel chest), pelvis, and other musculoskeletal areas are also covered, emphasizing acquired, post-injury or post-disease changes rather than congenital issues. This range helps coders and clinicians accurately categorize deformities from trauma, disease, or structural changes, facilitating precise treatment and insurance documentation.
