0.000What This Code Means
Inflammation where tendons and ligaments attach to the spine in the neck area.
Coding Tips
- •Confirm documentation specifies cervical region rather than cervicothoracic or other adjacent regions
- •Common presentation includes neck pain and reduced range of motion
Clinical Significance
Cervical spinal enthesopathy involves inflammation of ligament and tendon attachments throughout the neck region, often causing significant pain and stiffness that impacts daily activities. This condition frequently occurs as part of broader spondyloarthritis spectrum disorders.
Documentation Requirements
- ✓Clinical evidence of cervical entheseal inflammation
- ✓Imaging demonstrating cervical spine entheseal changes
- ✓Documentation of neck pain and stiffness patterns
- ✓Assessment of cervical spine range of motion
- ✓Evaluation for associated inflammatory arthritis
- ✓Response to NSAIDs and targeted therapy
- ✓Occupational impact assessment
- ✓Screening for extra-articular manifestations
