- ✓Established rheumatoid arthritis diagnosis with documented atypical features
- ✓Physical examination confirming right elbow joint involvement
- ✓Specific characteristics that classify this as 'other specified' RA variant
- ✓Assessment of elbow range of motion, flexion, and extension capabilities
- ✓Laboratory findings supporting active rheumatoid inflammatory disease
- ✓Functional evaluation of impact on arm use and occupational activities
- ✓Current anti-rheumatic treatment regimen and response
- ✓Imaging studies of right elbow when clinically indicated
