ICD Code M05.9

ICD code M05.9 is used to classify a diagnosis of rheumatoid arthritis with rheumatoid factor, unspecified. This code indicates that the patient has rheumatoid arthritis, a chronic inflammatory disorder affecting joints, and that rheumatoid factor, an antibody often present in this condition, has been detected. However, the specifics of the condition, such as the severity or the exact joints affected, are not detailed in this unspecified code.

1. Chronic Joint Pain and Swelling: Persistent pain and swelling in the joints, particularly in the hands, wrists, and knees, that lasts for more than six weeks.

2. Morning Stiffness: Stiffness in the joints that lasts for at least 30 minutes after waking up, often improving with movement.

3. Symmetrical Joint Involvement: Symptoms affecting the same joints on both sides of the body, such as both wrists or both knees.

4. Rheumatoid Nodules: Presence of firm lumps under the skin, typically over bony areas exposed to pressure.

5. Positive Rheumatoid Factor (RF) Test: Blood test results showing the presence of rheumatoid factor, an antibody often found in individuals with this condition.

6. Elevated Erythrocyte Sedimentation Rate (ESR) or C-Reactive Protein (CRP): Blood tests indicating inflammation in the body.

7. Radiographic Evidence: X-rays or other imaging showing joint erosion or bone deformities consistent with the condition.

8. Exclusion of Other Conditions: Ruling out other potential causes of symptoms, such as osteoarthritis or lupus, through clinical evaluation and testing.

9. Family History: Consideration of a family history of similar symptoms or autoimmune disorders, which may support the diagnosis.

10. Fatigue and General Malaise: General feelings of tiredness and unwellness that accompany joint symptoms.
