ICD-10 Code M05.62 – Rheumatoid arthritis of elbow with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.62 – Rheumatoid arthritis of elbow with involvement of other organs and systems
What it is
This code identifies rheumatoid arthritis affecting the elbow, with documented involvement of other organs or systems. Use it when the record clearly links the elbow joint disease to systemic rheumatoid disease.
Clinical signs
Typical findings include chronic inflammatory joint pain, swelling, stiffness, and reduced elbow motion. Clinical features vary; refer to documentation for evidence of extra-articular or systemic involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the elbow and notes involvement of other organs or systems. It may apply when the elbow is one of several affected joints and the chart supports systemic rheumatoid disease.
Make sure the documentation specifically identifies the elbow and the extra-articular involvement. If the record only mentions rheumatoid arthritis without site or systemic details, check documentation before assigning this code.
Do not use for
Do not use this code for osteoarthritis, traumatic elbow pain, or rheumatoid arthritis without elbow involvement. Do not assume systemic disease unless the provider documents it.
Coding tip
Verify both the elbow location and the “other organs and systems” wording in the note before coding.
