Flatback syndrome, thoracolumbar region

This code describes a spinal deformity characterized by a loss of the normal lordotic curve in the thoracolumbar spine, resulting in a flattened appearance. Patients typically present with an inability to stand erect, forward-leaning posture, and compensatory hip and knee flexion. This condition often leads to chronic back pain and functional limitations.

Apply this code when documentation explicitly states "flatback syndrome" affecting the thoracolumbar region. This diagnosis is typically made based on clinical examination and radiographic findings demonstrating a reduced or absent lumbar lordosis. It is often seen as a complication of spinal fusion surgery or degenerative disc disease.

• Ensure the documentation specifies the "thoracolumbar region" for accurate code assignment.
• Distinguish from other spinal deformities like kyphosis or scoliosis, which have distinct codes.
• Code any underlying causes or associated conditions, such as post-laminectomy syndrome or degenerative disc disease, in addition to this code.
