A condition where rheumatoid arthritis causes inflammation and muscle weakness in the right hand.
Coding Tips
- •Distinguish between hand involvement and wrist involvement; hand codes are separate from wrist codes
- •Document should clearly indicate right hand is affected with both arthritis and myopathy
Clinical Significance

The myopathy component suggests significant disease activity and potential for substantial functional limitations in activities of daily living requiring comprehensive management.
Documentation Requirements
- ✓Confirmed rheumatoid arthritis diagnosis with appropriate clinical or serological evidence
- ✓Clear documentation of right hand involvement with inflammatory arthritis
- ✓Evidence of myopathy with muscle weakness, wasting, or dysfunction
- ✓Clinical examination findings supporting both arthritis and muscle pathology
- ✓Exclusion of other causes of hand weakness or muscle disease
- ✓Functional assessment demonstrating impact on hand use and grip strength
- ✓Treatment response documentation for both inflammatory and myopathic components
