About M41.1
M41.1 is the ICD-10-CM diagnosis code for juvenile and adolescent idiopathic 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 2 subcodes must be used instead.
Within M41 (scoliosis), M41.1 is specifically for juvenile and adolescent idiopathic scoliosis. Related codes cover infantile idiopathic scoliosis (M41.0), other idiopathic scoliosis (M41.2), Thoracogenic scoliosis (M41.3), 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: M41.11 (scoliosis) and M41.12 (scoliosis).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
