0.000What This Code Means
A type of childhood arthritis affecting only a few joints, specifically involving the right ankle and foot. This causes inflammation and can affect walking and balance.
Coding Tips
- •Verify that right ankle and foot involvement is documented together
- •Note any associated foot deformities or gait abnormalities in the clinical record
Clinical Significance
Pauciarticular juvenile rheumatoid arthritis affecting the right ankle and foot represents a complex pediatric inflammatory condition that can severely impact mobility and normal development. Early diagnosis and aggressive treatment are crucial to prevent joint deformities, growth disturbances, and long-term functional limitations that can affect walking, running, and participation in age-appropriate activities.
Documentation Requirements
- ✓Physician diagnosis of juvenile rheumatoid arthritis with pauciarticular involvement
- ✓Specific documentation of right ankle and/or foot joint involvement
- ✓Clinical signs of inflammation in affected joints
- ✓Age at onset confirming pediatric presentation (typically <16 years)
- ✓Laboratory evidence of inflammatory process when available
- ✓Functional assessment including gait and mobility evaluation
- ✓Treatment plan addressing inflammation and maintaining joint function
- ✓Monitoring for complications including growth plate involvement
