ICD-10 Code M05.651 – Rheumatoid arthritis of right hip with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.651 – Rheumatoid arthritis of right hip with involvement of other organs and systems
What it is
This code identifies rheumatoid arthritis affecting the right hip, with documented involvement of other organs or systems. Use it when the record shows RA in that joint plus extra-articular disease.
Clinical signs
Typical findings include chronic inflammatory joint pain, stiffness, and reduced hip motion. Clinical features vary; refer to documentation for the specific organ or system involvement supporting the rheumatoid diagnosis.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the right hip and notes systemic involvement, such as other organ or body system manifestations. The laterality matters, so confirm the right hip is specified. If the record does not clearly link the systemic findings to rheumatoid arthritis, check documentation.
Do not use for
Do not use this code for rheumatoid arthritis without right-hip involvement, or for right-hip pain alone. Do not assign it when extra-articular involvement is not documented or is unrelated; check documentation.
Coding tip
Verify both the right-hip site and the documented systemic involvement before assigning M05.651.
