ICD-10 Code M05.011 – Felty’s syndrome, right shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.011 – Felty’s syndrome, right shoulder
What it is
This code identifies Felty’s syndrome affecting the right shoulder. It reflects a rheumatoid arthritis-related condition documented at that specific joint site.
Clinical signs
Clinical features vary; refer to documentation. In general, you may see chronic inflammatory joint symptoms, swelling, stiffness, and reduced shoulder range of motion when the right shoulder is involved.
When to use this code
Use this code when the provider documents Felty’s syndrome with involvement of the right shoulder. It is appropriate when the record clearly links the syndrome to that side and site.
Choose the code from the final assessment or problem list, not from suspected symptoms alone. If laterality or the exact diagnosis is unclear, check documentation before coding.
Do not use for
Do not use this code for unspecified shoulder pain, isolated rheumatoid arthritis, or Felty’s syndrome documented without right-shoulder involvement. Check documentation if the site or laterality is missing.
Coding tip
Confirm both the diagnosis and the right-sided shoulder site in the provider note before assigning M05.011.
