ICD Code M05.79

ICD code M05.79 is rheumatoid arthritis with rheumatoid factor affecting multiple sites in the body, but without any involvement of other organs or systems. This code is used to classify and document cases where rheumatoid arthritis is present in more than one joint or area, yet it does not extend its impact to other bodily systems.

1. Presence of Rheumatoid Factor: The patient must test positive for rheumatoid factor, which is an antibody found in the blood that can indicate the presence of rheumatoid arthritis.

2. Multiple Joint Involvement: The condition should affect multiple joints. This can include both small and large joints across different areas of the body.

3. Absence of Organ or System Involvement: There should be no evidence of involvement of other organs or systems. The condition should be limited to the joints without any systemic manifestations.

4. Chronic Inflammation: The patient should exhibit signs of chronic inflammation in the affected joints, which may include swelling, pain, and stiffness.

5. Symmetrical Joint Involvement: Typically, the condition should present symmetrically, meaning that the same joints on both sides of the body are affected.

6. Duration of Symptoms: Symptoms should persist for a minimum duration, often six weeks or more, to differentiate from other forms of arthritis or transient joint issues.

7. Radiographic Evidence: Imaging studies such as X-rays or MRIs may show joint erosion or other changes consistent with rheumatoid arthritis.

8. Exclusion of Other Diagnoses: Other potential causes of the symptoms, such as osteoarthritis or other autoimmune diseases, should be ruled out through clinical evaluation and testing.
