ICD-10 Code M05.03 – Felty’s syndrome, wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.03 – Felty’s syndrome, wrist
What it is
M05.03 identifies Felty’s syndrome affecting the wrist. You use it when rheumatoid arthritis with Felty’s syndrome is documented and the wrist is the specified site.
Clinical signs
Clinical features vary; refer to documentation. Felty’s syndrome is classically associated with rheumatoid arthritis, splenomegaly, and neutropenia, and the wrist may show inflammatory joint involvement.
When to use this code
Use this code when the provider documents Felty’s syndrome with wrist involvement or clearly links the wrist to the diagnosis. It is appropriate when the record specifies the site rather than only generalized disease. Check documentation if the laterality or joint site is unclear.
Do not use for
Do not use this code for rheumatoid arthritis of the wrist without Felty’s syndrome. Also avoid it when the diagnosis is only suspected or when the wrist is not the documented site.
Coding tip
Confirm both the syndrome and the wrist site in the note before assigning M05.03.
