0.000What This Code Means
Reiter's disease affecting the right hip joint, a reactive arthritis that develops following an infection in another part of the body.
Coding Tips
- •Confirm laterality is documented as right; if unspecified, use M02.359 instead
- •Document the triggering infection (commonly chlamydia or dysentery) to support medical necessity and treatment decisions
Clinical Significance
Reiter's disease affecting the right hip represents a severe form of reactive arthritis that significantly impacts mobility and weight-bearing function. This chronic inflammatory condition often requires aggressive immunosuppressive therapy and may lead to joint destruction, making it a high-priority diagnosis for risk adjustment and care management.
Documentation Requirements
- ✓Specific documentation of right hip joint involvement
- ✓Confirmed diagnosis of Reiter's disease with supporting clinical evidence
- ✓History of precipitating infection (genitourinary, enteric, or respiratory)
- ✓Physical examination findings of hip pain, stiffness, and range of motion limitation
- ✓Imaging studies showing joint inflammation or structural changes
- ✓Laboratory evidence of systemic inflammation
- ✓Assessment of ambulatory status and functional limitations
- ✓Treatment plan including DMARDs or biologic agents
