Other specified deforming dorsopathies, thoracolumbar region

This code signifies a non-specific, acquired structural deformity of the spine affecting the thoracic and/or lumbar regions, not elsewhere classified. It encompasses various conditions causing spinal malformation or abnormal curvature that don't fit more specific dorsopathy codes. This diagnosis indicates a structural alteration rather than a functional issue or acute injury.

Use this code for patients presenting with documented thoracolumbar spinal deformities that are not congenital, inflammatory, infectious, or due to trauma, and are not specifically defined by other M40-M43 codes. Supporting documentation should clearly describe the nature of the deformity and its location within the thoracic or lumbar spine, ruling out more specific diagnoses.

• Always seek more specific codes within the M40-M43 range if the documentation allows (e.g., kyphosis, lordosis, scoliosis).
• Ensure the documentation specifies "thoracolumbar region" or both "thoracic" and "lumbar" involvement; otherwise, consider codes for other spinal regions.
• This code is for acquired deformities; congenital deformities are classified under Q codes.
