0.000What This Code Means
Reiter's disease affecting an unspecified hip joint, a reactive arthritis that develops following an infection in another part of the body.
Coding Tips
- •Use this code only when the specific hip (right or left) is not documented; query provider if laterality can be determined
- •Document the triggering infection to establish the reactive nature of this arthritis
Clinical Significance
Reiter's disease affecting unspecified hip indicates reactive arthritis when laterality cannot be determined or bilateral hip involvement exists. This chronic inflammatory condition severely impacts mobility and quality of life, requiring comprehensive management and carrying significant implications for healthcare resource utilization.
Documentation Requirements
- ✓Documented diagnosis of Reiter's disease involving hip joint(s)
- ✓Clinical justification for unspecified laterality or bilateral hip involvement
- ✓Evidence of bacterial infection preceding arthritis onset
- ✓Assessment of hip joint inflammation and mobility impairment
- ✓Imaging studies demonstrating joint involvement
- ✓Laboratory evidence of inflammatory process
- ✓Functional evaluation including ambulatory status
- ✓Treatment plan with disease-modifying antirheumatic drugs
