Rheumatoid nodule, vertebrae

This code signifies the presence of a rheumatoid nodule specifically located on the vertebrae. These nodules are a characteristic extra-articular manifestation of rheumatoid arthritis, representing granulomatous inflammation. Their presence can indicate more severe or long-standing disease.

Apply this code when documentation clearly states the diagnosis of a rheumatoid nodule affecting the vertebral column. This typically occurs in patients with a confirmed diagnosis of rheumatoid arthritis. Supporting documentation would include imaging reports (e.g., MRI, CT) or pathology reports confirming the nodule's presence and location.

• Always code the underlying rheumatoid arthritis first, as the rheumatoid nodule is a manifestation of the systemic disease.
• Ensure the documentation specifies "vertebrae" as the location; do not use this code for nodules in other anatomical sites.
• Do not confuse with other spinal conditions or non-rheumatoid nodules; the etiology must be clearly linked to rheumatoid disease.
