Rheumatoid nodule, right wrist

This code identifies a rheumatoid nodule, a subcutaneous granuloma, specifically located on the right wrist. These nodules are a common extra-articular manifestation of rheumatoid arthritis, often firm and non-tender. Their presence indicates active or chronic inflammatory disease.

Apply this code when documentation clearly states the presence of a rheumatoid nodule on the patient's right wrist. This typically occurs in patients with a confirmed diagnosis of rheumatoid arthritis. Supporting documentation should include physical exam findings noting the nodule's location.

• Always confirm the specific anatomical location (right wrist) as nodules can occur elsewhere.
• Do not confuse with other types of wrist nodules, such as ganglion cysts or tenosynovitis.
• Sequence this code after the primary diagnosis of rheumatoid arthritis (e.g., M05.xx or M06.xx).
