What This Code Means

Inflammation of the spine affecting the area where the lower back and sacrum meet (lumbosacral region) without a specific identified cause.

Coding Tips

•Lumbosacral involvement is common in ankylosing spondylitis; document if specific diagnosis is known for more precise coding
•Ensure inflammation extends to include sacral involvement, not just lumbar

Clinical Significance

Unspecified inflammatory lumbosacral conditions affect the critical L5-S1 junction with impact on spinal mechanics and pelvic stability. Even without specific diagnosis, this location requires specialized anti-inflammatory management and biomechanical monitoring.

Documentation Requirements

✓Lumbosacral junction involvement (L5-S1)
✓Evidence of inflammatory process
✓Imaging of L5-S1 inflammatory changes
✓Lumbosacral stability assessment
✓Pelvic alignment evaluation
✓Inflammatory marker trends
✓Response to anti-inflammatory therapy
✓Plans for diagnostic specification

Commonly Confused Codes
