Rheumatoid nodule, right hand

This code identifies a rheumatoid nodule, which is a firm, non-tender subcutaneous lump, specifically located on the right hand. These nodules are a common extra-articular manifestation of rheumatoid arthritis, often found over bony prominences or pressure points.

Apply this code when documentation clearly indicates the presence of a rheumatoid nodule on the patient's right hand. This typically occurs in patients with a confirmed diagnosis of rheumatoid arthritis. Supporting documentation should specify the location of the nodule.

• Ensure the laterality (right hand) is explicitly documented.
• Do not confuse with other types of hand nodules, such as ganglion cysts or Heberden's nodes.
• Always code the underlying rheumatoid arthritis condition first, as the nodule is a manifestation of the systemic disease.
