ICD-10 Code M05.832 – Other rheumatoid arthritis with rheumatoid factor of left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.832 – Other rheumatoid arthritis with rheumatoid factor of left wrist
What it is
This code identifies rheumatoid arthritis affecting the left wrist, with rheumatoid factor present, but not classified under a more specific rheumatoid arthritis subtype. Use it when documentation clearly links the left wrist involvement to seropositive rheumatoid disease.
Clinical signs
Common findings include chronic inflammatory wrist pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation for evidence of rheumatoid factor positivity and left wrist involvement.
When to use this code
Use M05.832 when the provider documents rheumatoid arthritis with rheumatoid factor affecting only the left wrist or when the wrist is the specified joint in a broader seropositive RA diagnosis. You should code it from the documented site and laterality.
If the record states a different rheumatoid arthritis subtype, a different joint, or no rheumatoid factor association, choose the more accurate code. Check documentation when the laterality or serologic status is unclear.
Do not use for
Do not use this code for rheumatoid arthritis without rheumatoid factor, unspecified arthritis, or pain/swelling of the wrist without a documented RA diagnosis. Check documentation if the left wrist is not explicitly identified.
Coding tip
Confirm both the rheumatoid factor association and the left wrist laterality before assigning this code.
