0.000What This Code Means
Reiter's disease causing inflammation and pain in the right elbow joint as part of a reactive arthritis syndrome.
Coding Tips
- •Confirm the elbow location is clearly documented; do not assume based on patient handedness
- •Link this code to the underlying infection trigger when documented for complete clinical picture
Clinical Significance
Reiter's disease (reactive arthritis) of the right elbow represents a chronic autoimmune arthropathy that significantly impacts patient mobility and quality of life. This condition requires ongoing management with immunosuppressive therapies and carries substantial risk adjustment implications due to its chronic nature and potential for complications.
Documentation Requirements
- ✓Specific joint location documented as right elbow
- ✓Confirmation of Reiter's disease diagnosis with clinical criteria
- ✓Evidence of preceding infection (urogenital, gastrointestinal, or respiratory)
- ✓Documentation of inflammatory markers (ESR, CRP) if available
- ✓Assessment of joint swelling, pain, and range of motion limitations
- ✓History of classic triad symptoms (arthritis, urethritis, conjunctivitis) if present
- ✓Current treatment plan including DMARDs or biologics if prescribed
- ✓Functional status assessment and impact on activities of daily living
Commonly Confused Codes
M06.051 — Rheumatoid arthritis of right elbow requires positive RF or anti-CCP antibodies and symmetric joint involvementM02.821 — Other reactive arthropathies of right elbow lacks the specific Reiter's disease diagnosisM25.521 — Pain in right elbow is a symptom code, not a diagnosis of reactive arthritisM00.021 — Staphylococcal arthritis of right elbow is infectious, not reactive arthritis
