ICD-10 Code M06.02 – Rheumatoid arthritis without rheumatoid factor, elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.02 – Rheumatoid arthritis without rheumatoid factor, elbow
What it is
This code identifies rheumatoid arthritis affecting the elbow when rheumatoid factor is not present or not documented. It tells you the site and serologic status, so the record supports a specific inflammatory arthritis diagnosis.
Clinical signs
Typical findings include elbow pain, swelling, stiffness, warmth, and reduced range of motion. Clinical features vary; refer to documentation, especially when serology or joint involvement is not clearly stated.
When to use this code
Use M06.02 when the provider documents rheumatoid arthritis of the elbow and notes rheumatoid factor negative or absent. It also fits when the elbow is the documented involved joint and the chart supports seronegative rheumatoid arthritis. Check documentation if laterality or serologic status is unclear.
Do not use for
Do not use this code for elbow pain, osteoarthritis, or other inflammatory arthritides without rheumatoid arthritis. Also avoid it when the record does not support elbow involvement or does not indicate absence of rheumatoid factor.
Coding tip
Verify both the joint and rheumatoid factor status in the provider note before assigning M06.02.
