Rheumatoid nodule, unspecified site

This code signifies the presence of a rheumatoid nodule, which is a firm, non-tender subcutaneous lump, typically found over pressure points or extensor surfaces, that is characteristic of rheumatoid arthritis. It represents a granulomatous inflammatory lesion associated with the disease.

Use this code when documentation confirms a rheumatoid nodule but the specific anatomical location is not specified by the provider. This is appropriate when the physician notes "rheumatoid nodule" without further detail regarding its site.

• Always query the provider for a more specific site if possible, as more specific codes exist (e.g., M06.31-M06.39).
• This code should be sequenced after the primary diagnosis for rheumatoid arthritis (e.g., M05.xx or M06.xx).
• Ensure the medical record clearly states "rheumatoid nodule" and not another type of nodule.
