Kissing spine, occipito-atlanto-axial region

This code represents a "kissing spine" or Baastrup's disease affecting the occipital, atlas, and axis vertebrae. This condition involves close approximation and contact of adjacent spinous processes, leading to degenerative changes, bone marrow edema, and potential pain due to chronic friction.

Apply this code when documentation explicitly states Baastrup's disease or kissing spine specifically located in the occipito-atlanto-axial region. Supporting documentation typically includes imaging reports (X-ray, MRI, CT) detailing the close approximation and degenerative changes of the spinous processes in this cervical area, along with clinical notes describing associated symptoms like localized pain.

• Ensure the documentation specifies the occipito-atlanto-axial region; do not use for kissing spine in other spinal segments.
• Code any associated pain separately if documented and not integral to the kissing spine diagnosis.
• Distinguish from other spinal degenerative conditions; this code is specific to the spinous process contact.
