Rheumatoid nodule, right hip

This code signifies the presence of a rheumatoid nodule, a subcutaneous granuloma characteristic of rheumatoid arthritis, specifically located on the patient's right hip. These nodules are typically firm, non-tender, and can vary in size.

Apply this code when documentation clearly identifies a rheumatoid nodule on the right hip of a patient with a confirmed diagnosis of rheumatoid arthritis. This code is appropriate for both initial encounters and subsequent follow-up visits where the nodule is assessed.

• Always ensure the documentation specifies "right hip" to support this laterality.
• Code M06.351 should be sequenced after the primary code for rheumatoid arthritis (e.g., M05.xx or M06.xx).
• Differentiate from other subcutaneous nodules not associated with rheumatoid arthritis, which would be coded differently.
