About M40.29

M40.29 is the ICD-10-CM diagnosis code for other kyphosis. It belongs to category M40 (kyphosis and lordosis), 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 5 subcodes must be used instead.

Within M40.2, choose M40.29 (Other kyphosis) only when documentation doesn't support a more specific option: unspecified kyphosis (M40.20).

To report this condition, pick the subcode that matches the documentation: M40.292 (cervical region), M40.293 (cervicothoracic region), M40.294 (thoracic region), M40.295 (thoracolumbar region) and M40.299 (site unspecified).

Code first: underlying disease.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
