0.000What This Code Means
A form of rheumatoid arthritis affecting the right hip joint, characterized by inflammation and joint damage that doesn't fit into other specific rheumatoid arthritis categories.
Coding Tips
- •Verify laterality is documented as right hip in the medical record before assigning this code
- •Ensure the diagnosis specifies 'other specified rheumatoid arthritis' rather than seropositive or seronegative RA to use M06.8x codes
Clinical Significance
Other specified rheumatoid arthritis of the right hip indicates an atypical RA variant affecting a major weight-bearing joint crucial for mobility and ambulation. Hip involvement represents severe disease that significantly impacts quality of life and functional independence.
Documentation Requirements
- ✓Confirmed rheumatoid arthritis diagnosis with specific atypical characteristics
- ✓Physical examination documenting right hip joint involvement
- ✓Description of features that distinguish this as 'other specified' RA type
- ✓Assessment of hip range of motion and weight-bearing capacity
- ✓Laboratory evidence supporting active rheumatoid disease process
- ✓Functional evaluation of ambulation and mobility limitations
- ✓Pain assessment and impact on activities of daily living
- ✓Imaging studies of right hip joint when clinically indicated
