0.000What This Code Means
Reiter's disease affecting multiple joints throughout the body simultaneously.
Coding Tips
- •Use this code when Reiter's disease involves 3 or more different joint sites
- •Document all affected sites in the medical record for accurate coding justification
Clinical Significance
Reiter's disease affecting multiple sites represents the most comprehensive form of reactive arthritis with systemic involvement affecting multiple joint systems simultaneously. This condition requires intensive immunosuppressive management and has the highest impact on patient function, disability, and healthcare resource utilization.
Documentation Requirements
- ✓Documented diagnosis of Reiter's disease with multiple joint involvement
- ✓Specific identification of all affected joint sites
- ✓Evidence of systemic inflammatory process
- ✓History of precipitating bacterial infection
- ✓Assessment of overall functional status and disability level
- ✓Laboratory markers demonstrating systemic inflammation
- ✓Treatment with combination immunosuppressive therapy
- ✓Evaluation for extra-articular manifestations (skin, eyes, cardiac)
Commonly Confused Codes
M06.09 — Rheumatoid arthritis, unspecified, multiple sites has different serology and patternM02.89 — Other reactive arthropathies, multiple sites lacks specific Reiter's diagnosisM35.3 — Polymyalgia rheumatica affects muscles rather than joints primarilyM79.3 — Panniculitis, unspecified affects subcutaneous tissue rather than joints
