ICD-10 Code M06.032 – Rheumatoid arthritis without rheumatoid factor, left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.032 – Rheumatoid arthritis without rheumatoid factor, left wrist
What it is
This code identifies rheumatoid arthritis affecting the left wrist when rheumatoid factor is not present. Use it for a documented seronegative rheumatoid arthritis diagnosis in that joint.
Clinical signs
Typical findings include persistent inflammatory joint pain, swelling, stiffness, and reduced wrist motion. Clinical features vary; refer to documentation, and confirm the left wrist site and absence of rheumatoid factor.
When to use this code
Use this code when the provider documents rheumatoid arthritis without rheumatoid factor specifically in the left wrist. It fits confirmed seronegative RA limited to, or clearly involving, that joint. If documentation names multiple joints or does not specify the wrist side, check documentation.
Do not use for
Do not use it for rheumatoid arthritis with rheumatoid factor, or for nonspecific wrist pain, osteoarthritis, or other inflammatory arthropathies. If the record does not confirm seronegative RA in the left wrist, choose a different code.
Coding tip
Verify both laterality and seronegative status in the provider note before assigning M06.032.
