Kissing spine, cervicothoracic region

This code signifies a specific type of spinal osteoarthritis where the spinous processes of adjacent vertebrae in the cervicothoracic region are in close proximity or make contact, leading to friction and pain. This contact can cause degenerative changes, bone remodeling, and sclerosis at the affected vertebral levels.

Utilize this code when documentation explicitly states "kissing spine" or "Baastrup's disease" affecting the cervicothoracic junction. Supporting documentation typically includes imaging reports (X-ray, MRI, CT) demonstrating close approximation or contact of spinous processes, often accompanied by clinical notes detailing localized pain and tenderness in this spinal segment.

• Ensure the documentation specifies the cervicothoracic region; other spinal regions have distinct codes.
• Do not confuse with general spondylosis or osteoarthritis without explicit mention of kissing spine.
• Code any associated pain (e.g., M54.2, Cervicalgia) as a secondary diagnosis if documented.
