ICD-10 Code M06.221 – Rheumatoid bursitis, right elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.221 – Rheumatoid bursitis, right elbow
What it is
M06.221 identifies rheumatoid bursitis affecting the right elbow. It means the bursa around that joint is inflamed in the setting of rheumatoid arthritis.
Clinical signs
Typical findings include elbow pain, swelling, tenderness, and reduced motion. Clinical features vary; refer to documentation for evidence of rheumatoid involvement and right-sided location.
When to use this code
Use this code when the provider documents rheumatoid bursitis specifically in the right elbow. You should confirm both the rheumatoid cause and the anatomic site in the record.
Do not assign it for nonspecific elbow bursitis or for bursitis without a documented rheumatoid link. If the note is unclear, check documentation before coding.
Do not use for
Do not use this code for bursitis of the left elbow, bilateral elbow bursitis, or nonrheumatoid bursitis. Check documentation if the diagnosis only states elbow pain or swelling.
Coding tip
Verify that the provider links the bursitis to rheumatoid arthritis and specifies the right elbow before assigning M06.221.
