Rheumatoid nodule, right elbow

This code identifies a subcutaneous nodule, characteristic of rheumatoid arthritis, located specifically on the right elbow. These nodules are typically firm, non-tender, and can vary in size, often forming over pressure points. They represent a common extra-articular manifestation of rheumatoid disease.

Apply this code when documentation clearly indicates the presence of a rheumatoid nodule on the patient's right elbow. This diagnosis is typically supported by physical examination findings, patient history of rheumatoid arthritis, and sometimes imaging studies. It should be used in conjunction with a code for the underlying rheumatoid arthritis.

• Always sequence this code after the primary diagnosis code for the specific type of rheumatoid arthritis (e.g., M05.xx or M06.xx).
• Ensure laterality is accurately documented; distinguish between right (1), left (2), and bilateral (9) elbow involvement.
• Do not confuse with other types of elbow nodules, such as gouty tophi or olecranon bursitis, which have distinct codes.
