ICD-10 Code M05.741 – Rheumatoid arthritis with rheumatoid factor of right hand without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.741 – Rheumatoid arthritis with rheumatoid factor of right hand without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting the right hand, with a documented rheumatoid factor, and no organ or system involvement beyond the joint disease. Use it when the condition is limited to the hand.
Clinical signs
Typical findings include inflammatory joint pain, swelling, stiffness, and reduced hand function. Clinical features vary; refer to documentation, and confirm the right hand is specifically involved.
When to use this code
Use this code when the record clearly states rheumatoid arthritis with rheumatoid factor in the right hand only. It fits visits where the provider documents joint involvement without extra-articular disease. If the note does not specify the side or mentions organ involvement, check documentation.
Do not use for
Do not use it for rheumatoid arthritis without rheumatoid factor, unspecified hand laterality, or disease involving organs or other systems. Check documentation if the record is unclear.
Coding tip
Confirm both the rheumatoid factor status and right-hand laterality before assigning M05.741.
