Rheumatoid nodule, right shoulder

This code signifies the presence of a rheumatoid nodule specifically located on the right shoulder. Rheumatoid nodules are firm, non-tender subcutaneous lumps that commonly develop in patients with rheumatoid arthritis, often over pressure points or extensor surfaces. Their presence indicates a more severe or active form of the underlying autoimmune disease.

Apply this code when documentation clearly identifies a rheumatoid nodule on the patient's right shoulder. This typically occurs in patients with a confirmed diagnosis of rheumatoid arthritis. Supporting documentation should include physical exam findings noting the nodule's presence and location, or imaging reports confirming its existence in the specified anatomical area.

• Always confirm the specific anatomical site (right shoulder) to ensure accurate coding.
• Do not confuse with other types of shoulder nodules or masses; ensure the documentation explicitly states "rheumatoid nodule."
• This code should be sequenced after the primary diagnosis code for rheumatoid arthritis (e.g., from the M05 or M06 categories, excluding M06.3-).
