0.000What This Code Means
A rare autoimmune disease affecting skin and muscles with involvement of other organs such as the lungs, heart, or gastrointestinal system.
Coding Tips
- •Document which specific organs are involved as this code indicates multi-system involvement
- •Consider using additional codes to specify the organ involvement for better clinical clarity
Clinical Significance
Unspecified dermatopolymyositis with other organ involvement indicates complex multi-system inflammatory disease requiring specialized management and coordination between multiple subspecialties. These patients typically have more severe disease with higher treatment complexity.
Documentation Requirements
- ✓Evidence of inflammatory myopathy with skin involvement
- ✓Documentation of specific organ systems involved beyond muscle/respiratory
- ✓Evidence of organ dysfunction or inflammation
- ✓Documentation that specific myositis subtype is unclear
- ✓Multidisciplinary treatment plan
- ✓Monitoring plan for affected organ systems
- ✓Coordination with appropriate subspecialists
- ✓Assessment of overall disease activity
