ICD-10 Code M05.751 – Rheumatoid arthritis with rheumatoid factor of right hip without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.751 – Rheumatoid arthritis with rheumatoid factor of right hip without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting the right hip in a patient who has rheumatoid factor positivity. It also specifies that the disease is limited to the joint and has no documented organ or system involvement.
Clinical signs
Typical findings include chronic inflammatory joint pain, stiffness, swelling, and reduced range of motion in the right hip. Clinical features vary; refer to documentation for evidence of rheumatoid factor positivity and absence of extra-articular involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis with rheumatoid factor affecting the right hip and states that no organ or system involvement is present. It is appropriate for encounters focused on the hip joint disease, whether newly assessed or followed over time. If laterality, rheumatoid factor status, or systemic involvement is unclear, check documentation.
Do not use for
Do not use this code for rheumatoid arthritis without rheumatoid factor, for involvement of another hip, or when systemic manifestations are documented. Check documentation if the record does not clearly support the right-sided, factor-positive diagnosis.
Coding tip
Confirm both laterality and the “without organ or systems involvement” statement before assigning M05.751.
