Kissing spine, site unspecified

This code represents a diagnosis of kissing spine, also known as Baastrup's disease, where the spinous processes of adjacent vertebrae abnormally touch or "kiss." This contact can lead to degenerative changes, inflammation, and pain due to impingement. The "site unspecified" indicates that the specific vertebral level affected is not documented.

Use this code when documentation confirms a diagnosis of kissing spine but does not specify the exact location (e.g., cervical, thoracic, lumbar). This typically occurs when imaging reports (X-ray, MRI) identify the condition without pinpointing the precise vertebral segment. Documentation should clearly state "kissing spine" or "Baastrup's disease" without further anatomical detail.

• Avoid using this code if the specific vertebral level is documented; instead, use a more specific code from the M48.2 subcategory.
• Always review imaging reports and physician notes for precise anatomical location before defaulting to "site unspecified."
• Consider sequencing this code after a pain diagnosis (e.g., M54.5 for low back pain) if the kissing spine is identified as the underlying cause.
