What This Code Means

A type of childhood arthritis with systemic symptoms that affects the spine and vertebrae.

Coding Tips

•Document the specific vertebral level(s) affected when possible for clinical clarity
•Distinguish from ankylosing spondylitis and other spondyloarthropathies by confirming JRA diagnosis

Clinical Significance

Juvenile rheumatoid arthritis with systemic onset affecting the vertebrae represents a particularly severe form requiring intensive management due to spinal involvement. Vertebral involvement in JRA can lead to growth abnormalities, spinal deformities, and significant functional limitations requiring multidisciplinary care including rheumatology, orthopedics, and physical therapy.

Documentation Requirements

✓Patient age at onset (must be under 16 years)
✓Evidence of systemic symptoms (fever, rash, lymphadenopathy, hepatosplenomegaly)
✓Documentation of vertebral/spinal joint involvement with inflammation
✓Laboratory evidence of systemic inflammation (elevated ESR, CRP)
✓Exclusion of other causes of arthritis and systemic illness
✓Duration of symptoms (minimum 6 weeks for JRA diagnosis)
✓Physical examination findings of spinal stiffness, pain, or deformity
✓Imaging studies showing vertebral joint involvement or changes

Commonly Confused Codes
