2026 ICD-10-CM Diagnosis Code M05.031 – Felty’s syndrome, right wrist
What it is
M05.031 identifies Felty’s syndrome affecting the right wrist. It indicates rheumatoid arthritis with the Felty syndrome component documented for that specific joint site.
Clinical signs
Clinical features vary; refer to documentation. Felty’s syndrome is classically associated with long-standing rheumatoid arthritis and may include splenomegaly and neutropenia.
When to use this code
Use this code when the provider documents Felty’s syndrome involving the right wrist, or a right-wrist manifestation tied to that diagnosis. Confirm laterality and the exact site in the record before assigning the code.
Do not use for
Do not use this code for unspecified wrist involvement or for rheumatoid arthritis without documented Felty’s syndrome. Check documentation if the record only mentions arthritis, pain, or swelling.
Coding tip
Verify both the syndrome and the right-sided location in the note; laterality drives correct code selection.
