About M41.0
M41.0 is the ICD-10-CM diagnosis code for infantile 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 8 subcodes must be used instead.
Within M41 (scoliosis), M41.0 is specifically for infantile idiopathic scoliosis. Related codes cover juvenile and adolescent idiopathic scoliosis (M41.1), 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: M41.00 (site unspecified), M41.02 (cervical region), M41.03 (cervicothoracic region), M41.04 (thoracic region), M41.05 (thoracolumbar region), M41.06 (lumbar region), M41.07 (lumbosacral region) and M41.08 (sacral and sacrococcygeal region).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
