Kissing spine, thoracolumbar region

This code signifies Baastrup's disease, also known as "kissing spine," specifically affecting the thoracolumbar region of the vertebral column. It describes a degenerative condition where adjacent spinous processes hypertrophy and come into contact, leading to friction, inflammation, and pain. This contact can result in pseudarthrosis formation and bursitis.

Apply this code when documentation explicitly states Baastrup's disease or "kissing spine" in the thoracolumbar spine. Supporting documentation typically includes imaging reports (X-ray, MRI, CT) demonstrating close approximation or contact of spinous processes, often with associated degenerative changes, and clinical notes detailing localized pain and tenderness in the thoracolumbar region.

• Ensure the documentation specifies the thoracolumbar region; other spinal regions have different codes.
• Do not confuse with general spondylosis or other degenerative spinal conditions unless Baastrup's disease is explicitly diagnosed.
• Code any associated pain (e.g., M54.5 for low back pain) as a secondary diagnosis if documented.
