ICD-10 Code M05.732 – Rheumatoid arthritis with rheumatoid factor of left wrist without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.732 – Rheumatoid arthritis with rheumatoid factor of left wrist without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting the left wrist in a patient with rheumatoid factor positivity and no documented organ or system involvement. Use it when the record specifies this joint and confirms the seropositive form.
Clinical signs
Typical findings include chronic inflammatory joint pain, swelling, stiffness, and reduced wrist motion. Clinical features vary; refer to documentation for the affected joint, rheumatoid factor status, and whether extra-articular disease is absent.
When to use this code
Use this code when the provider documents rheumatoid arthritis with rheumatoid factor involving only the left wrist. It also fits records that clearly state no organ or systems involvement. If the note does not specify the side or seropositive status, check documentation.
Do not use for
Do not use this code for rheumatoid arthritis without rheumatoid factor, or when the right wrist or another joint is documented instead. Do not assign it if organ or system involvement is present.
Coding tip
Confirm both the left-sided wrist site and rheumatoid factor positivity in the assessment before coding.
