Rheumatoid nodule, left hand

This code identifies the presence of a rheumatoid nodule specifically located on the left hand. Rheumatoid nodules are firm, non-tender subcutaneous lumps that commonly occur in patients with rheumatoid arthritis, often over pressure points or extensor surfaces. They represent a specific extra-articular manifestation of the disease.

Use this code when documentation clearly indicates a rheumatoid nodule is present on the patient's left hand. This diagnosis is typically made through physical examination and is often associated with a confirmed diagnosis of rheumatoid arthritis. The physician's notes should specify the location of the nodule.

• Always confirm the specific hand (left or right) and the presence of a nodule. Do not assume laterality if not explicitly stated.
• This code should be sequenced after the primary diagnosis for rheumatoid arthritis (e.g., M05.xx or M06.xx).
• Differentiate from other subcutaneous nodules that are not rheumatoid in origin, such as gouty tophi or epidermal cysts.
