ICD-10 Code M05.69 – Rheumatoid arthritis of multiple sites with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.69 – Rheumatoid arthritis of multiple sites with involvement of other organs and systems
What it is
This code identifies seropositive rheumatoid arthritis affecting multiple joints, with documented involvement of other organs or systems. Use it when the record shows rheumatoid arthritis beyond the joints.
Clinical signs
Typical findings include symmetric inflammatory joint pain, swelling, stiffness, and reduced range of motion. Extra-articular involvement may be documented in organs or systems; clinical features vary, so refer to documentation.
When to use this code
Use M05.69 when the provider documents rheumatoid arthritis in multiple sites and also notes involvement of another organ or system. The diagnosis should be clearly stated in the chart, not inferred from symptoms alone. If the record does not specify the extra-articular involvement, check documentation before coding.
Do not use for
Do not use this code for rheumatoid arthritis limited to one site, or when the chart does not mention other organ or system involvement. If documentation is nonspecific, check documentation for a more accurate code.
Coding tip
Confirm both “multiple sites” and “with involvement of other organs and systems” are documented before assigning M05.69.
