About M42.0
M42.0 is the ICD-10-CM diagnosis code for juvenile osteochondrosis of spine. It belongs to category M42 (spinal osteochondrosis), 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 10 subcodes must be used instead.
Within M42 (spinal osteochondrosis), M42.0 is specifically for juvenile osteochondrosis of spine. Related codes cover adult osteochondrosis of spine (M42.1) and unspecified (M42.9).
To report this condition, pick the subcode that matches the documentation: M42.00 (site unspecified), M42.01 (occipito-atlanto-axial region), M42.02 (cervical region), M42.03 (cervicothoracic region), M42.04 (thoracic region), M42.05 (thoracolumbar region), M42.06 (lumbar region), M42.07 (lumbosacral region) and 2 more.
Don't report M42.0 together with the conditions in its Excludes1 note: postural kyphosis (M40.0).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
