ICD-10 Code M05.7 – Rheumatoid arthritis with rheumatoid factor without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.7 – Rheumatoid arthritis with rheumatoid factor without organ or systems involvement
What it is
This code identifies rheumatoid arthritis with a positive rheumatoid factor, but without documented involvement of organs or other body systems. Use it when the record supports rheumatoid arthritis and does not describe extra-articular disease.
Clinical signs
Typical findings include chronic inflammatory joint pain, swelling, stiffness, and symmetric small-joint involvement. Clinical features vary; refer to documentation for rheumatoid factor positivity and any mention of systemic or organ involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis with rheumatoid factor and specifically states there is no organ or systems involvement. It fits office, rheumatology, or inpatient notes that describe joint disease only. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code if rheumatoid factor is absent or if the chart documents organ, vascular, pulmonary, or other systemic involvement. Do not assume extra-articular disease without explicit provider documentation.
Coding tip
Confirm both the rheumatoid factor and the absence of organ or systems involvement in the provider note before assigning M05.7.
