Oth acquired deformities of ms sys and connective tissue
Other acquired deformities of musculoskeletal system and connective tissue
M95 is a header (parent) code in the ICD-10-CM hierarchy. It is not billable for claim submission. Use one of the billable child codes listed below.
Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
M95.0 identifies a structural deformity of the nose that developed after birth — the result of trauma, disease, or prior surgery rather than a congenital malformation.
M95.2 captures acquired (non-congenital) structural deformities of the head — including skull asymmetry, plagiocephaly, facial bone deformity, and calcified hematomas — that developed after birth due to trauma, positional pressure, surgery, or other external causes.
Structural deformity of the neck region that developed after birth — resulting from injury, surgery, infection, inflammatory disease, or other acquired cause — rather than being present at birth.
M95.4 identifies a structural deformity of the chest wall or ribs that developed after birth as a result of disease, injury, surgery, or another acquired cause — not a congenital malformation.
M95.5 identifies a structural deformity of the pelvis that developed after birth — not a congenital anomaly — including changes to the ilium, ischium, or overall pelvic architecture resulting from disease, injury, or mechanical stress.
M95.8 captures acquired deformities of the musculoskeletal system that don't fit any more specific code within the M95 category — a true 'other specified' bucket for non-congenital structural abnormalities not classified elsewhere.
M95.9 identifies an acquired deformity of the musculoskeletal system when the specific site, structure, or type of deformity is not documented or cannot be determined.
