ICD-10 Code M05.83 – Other rheumatoid arthritis with rheumatoid factor of wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.83 – Other rheumatoid arthritis with rheumatoid factor of wrist
What it is
This code identifies rheumatoid arthritis affecting the wrist when rheumatoid factor is present and the condition does not fit a more specific rheumatoid arthritis category. Use it for documented RA involving the wrist with seropositive status.
Clinical signs
Typical findings include chronic wrist pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation, especially for evidence of rheumatoid factor positivity and inflammatory joint involvement.
When to use this code
Use this code when the record clearly states rheumatoid arthritis with rheumatoid factor affecting the wrist and no more specific ICD-10-CM option applies. It fits outpatient or inpatient documentation that names the wrist as the involved joint. Check documentation if laterality or a more specific rheumatoid arthritis subtype is recorded.
Do not use for
Do not use it for rheumatoid arthritis without rheumatoid factor, or when the wrist problem is better described as osteoarthritis, trauma, or another non-rheumatoid joint disorder. Check documentation if the provider does not specify rheumatoid factor.
Coding tip
Confirm both the rheumatoid factor status and the wrist site in the provider note before assigning M05.83.
