2026 ICD-10-CM Diagnosis Code M06.011 – Rheumatoid arthritis without rheumatoid factor, right shoulder
What it is
This code identifies rheumatoid arthritis affecting the right shoulder when rheumatoid factor is not present. Use it for a documented rheumatoid arthritis diagnosis limited to that joint.
Clinical signs
Typical findings include shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for evidence of rheumatoid arthritis without rheumatoid factor.
When to use this code
Use M06.011 when the provider documents rheumatoid arthritis without rheumatoid factor in the right shoulder. It fits encounters where the right shoulder is the only specified site or the most specific documented site.
If the record says rheumatoid arthritis but does not specify factor status or laterality, check documentation before coding. Choose the most specific code supported by the note.
Do not use for
Do not use this code for rheumatoid arthritis with rheumatoid factor, other shoulder involvement, or unspecified shoulder laterality. Check documentation if the diagnosis is unclear or incomplete.
Coding tip
Confirm both factor status and right shoulder laterality in the provider note before assigning M06.011.
