M40.10 identifies other secondary kyphosis — an abnormal posterior spinal curvature caused by an underlying disease or condition — when the specific spinal region affected is not documented.
Acquired posterior curvature of the cervical spine arising from a non-postural, non-congenital underlying cause — classified as 'other secondary' to distinguish it from postural kyphosis and from conditions with their own dedicated codes.
Secondary kyphosis localized to the cervicothoracic junction (C7–T1 region), arising from an identifiable underlying disease process rather than postural habit or congenital deformity.
M40.14 identifies kyphosis of the thoracic spine that is secondary to an underlying condition — not postural in origin and not congenital, postprocedural, or part of a kyphoscoliosis pattern.
M40.15 classifies acquired kyphosis of the thoracolumbar junction (T10-L2 vertebral segment) that results from an identifiable underlying condition other than postural habit or congenital malformation.
