Postural kyphosis, cervicothoracic region

This code signifies an abnormal, exaggerated anterior-posterior curvature of the spine, specifically in the cervicothoracic region, that is primarily due to poor posture rather than a structural deformity. It represents a flexible kyphosis that can often be corrected voluntarily or with physical therapy.

Apply this code when documentation clearly indicates a diagnosis of kyphosis in the neck and upper back area attributed to postural factors. This diagnosis is typically made after ruling out fixed structural deformities, Scheuermann's disease, or congenital anomalies. Supporting documentation would include physical exam findings noting a reducible kyphosis and absence of vertebral wedging or other structural changes on imaging.

• Differentiate from structural kyphosis (e.g., M40.1x, M40.2x) which involves fixed vertebral deformities.
• Ensure the documentation specifies "postural" and the cervicothoracic region to accurately assign this code.
• Do not use for kyphosis due to underlying diseases like osteoporosis or tuberculosis; those conditions would be coded first, with kyphosis as a secondary manifestation.
