ICD-10 Code M05.719 – Rheumatoid arthritis with rheumatoid factor of unspecified shoulder without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.719 – Rheumatoid arthritis with rheumatoid factor of unspecified shoulder without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting an unspecified shoulder, with rheumatoid factor present and no documented organ or system involvement. Use it when the record names RA in the shoulder but does not specify right or left.
Clinical signs
Typical findings include chronic shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for laterality, rheumatoid factor status, and any extra-articular disease.
When to use this code
Use M05.719 when the provider documents rheumatoid arthritis with rheumatoid factor in an unspecified shoulder and does not mention organ or system involvement. It fits outpatient, inpatient, or problem-list documentation when laterality is not recorded. If the note specifies right or left shoulder, choose the laterality-specific code instead.
Do not use for
Do not use this code for rheumatoid arthritis without rheumatoid factor, or for shoulder pain without a confirmed RA diagnosis. Check documentation if the record shows organ involvement or a different joint.
Coding tip
Confirm both rheumatoid factor positivity and the unspecified shoulder before assigning this code.
