Congenital lordosis, thoracolumbar region

This code describes an abnormal, exaggerated inward curvature of the spine in the thoracolumbar region that is present at birth. This congenital deformity results in a swayback appearance affecting the junction of the thoracic and lumbar vertebrae. It is a structural anomaly, not a postural one.

Use this code for patients diagnosed with a congenital lordosis specifically located in the thoracolumbar spine. Documentation should clearly state the congenital nature of the lordosis and specify its location to the thoracolumbar region. This code is appropriate when the lordosis is identified as a birth defect.

• Differentiate from acquired lordosis (M40.5x) or postural lordosis, which are not congenital.
• Ensure documentation specifies "congenital" and "thoracolumbar region" to support this specific code.
• Do not confuse with scoliosis (Q67.5) or kyphosis (Q76.41x), which are different spinal deformities.
