Kissing spine, lumbosacral region

This code signifies Baastrup's disease affecting the lower back and sacrum. It describes an acquired spinal condition characterized by approximation and contact of adjacent spinous processes, leading to degenerative changes and potential pain. This contact often results in hypertrophy, sclerosis, and bursitis between the spinous processes.

Use this code when documentation explicitly states "kissing spine" or "Baastrup's disease" localized to the lumbosacral spinal region. Supporting documentation typically includes imaging findings (e.g., X-ray, MRI) demonstrating close approximation, hypertrophy, or degenerative changes of the spinous processes in the L1-S1 segments.

• Ensure the documentation specifies the lumbosacral region; other spinal regions have different codes.
• Do not confuse with general degenerative disc disease (M51.3-) unless Baastrup's disease is specifically diagnosed.
• Code any associated pain (e.g., M54.5-) as a secondary diagnosis, if documented.
