About M41.3
M41.3 is the ICD-10-CM diagnosis code for Thoracogenic scoliosis. It belongs to category M41 (scoliosis), block M40-M43 (deforming dorsopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within M41 (scoliosis), M41.3 is specifically for Thoracogenic scoliosis. Related codes cover infantile idiopathic scoliosis (M41.0), juvenile and adolescent idiopathic scoliosis (M41.1), other idiopathic scoliosis (M41.2), neuromuscular scoliosis (M41.4), other secondary scoliosis (M41.5), other forms of scoliosis (M41.8) and unspecified (M41.9).
To report this condition, pick the subcode that matches the documentation: M41.30 (site unspecified), M41.34 (thoracic region) and M41.35 (thoracolumbar region).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
