ICD-10 Code M06.239 – Rheumatoid bursitis, unspecified wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.239 – Rheumatoid bursitis, unspecified wrist
What it is
M06.239 identifies rheumatoid bursitis affecting the wrist when the side is not specified. Use it for bursitis linked to rheumatoid arthritis, not for simple overuse or traumatic bursitis.
Clinical signs
Typical findings include wrist pain, swelling, tenderness, and reduced motion around the bursa. Clinical features vary; refer to documentation for confirmation of rheumatoid involvement and the unspecified wrist location.
When to use this code
Use this code when the record documents rheumatoid bursitis in the wrist but does not identify right or left. It fits cases where the provider links the bursitis to rheumatoid disease. If the note only says wrist bursitis without rheumatoid cause, check documentation.
Do not use for
Do not use it for nonrheumatoid bursitis, traumatic bursitis, or bursitis at a different site. If the wrist side is documented, choose the appropriate laterality code instead.
Coding tip
Confirm both the rheumatoid etiology and the unspecified wrist before assigning M06.239.
