ICD-10 Code M05.632 – Rheumatoid arthritis of left wrist with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.632 – Rheumatoid arthritis of left wrist with involvement of other organs and systems
What it is
This code identifies rheumatoid arthritis affecting the left wrist, with documented involvement beyond the joint itself. Use it when the record shows systemic or extra-articular disease linked to rheumatoid arthritis.
Clinical signs
Typical findings include chronic inflammatory wrist pain, swelling, stiffness, and reduced range of motion. Clinical features vary; refer to documentation for evidence of other organ or system involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the left wrist and specifically notes involvement of other organs or systems. It fits cases where the wrist is the named site and the disease is not limited to the joint. If the record does not clearly state systemic involvement, check documentation before assigning this code.
Do not use for
Do not use this code for rheumatoid arthritis limited to the left wrist without extra-articular involvement. Also avoid it when the affected site is another joint or when the documentation is unclear; check documentation.
Coding tip
Confirm both the left wrist site and the systemic involvement are explicitly documented before coding M05.632.
