ICD-10 Code M05.051 – Felty’s syndrome, right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.051 – Felty’s syndrome, right hip
What it is
M05.051 identifies Felty’s syndrome affecting the right hip. Use it when documentation links the condition to the right hip and you need the specific laterality-coded diagnosis.
Clinical signs
Felty’s syndrome is a rheumatoid arthritis-associated disorder classically linked with splenomegaly and neutropenia. Clinical features vary; refer to documentation for the recorded hip involvement.
When to use this code
Use this code when the provider documents Felty’s syndrome with right hip involvement, or clearly assigns the diagnosis to that side. It is appropriate when the record supports a laterality-specific diagnosis for the hip. Check documentation if the note only mentions Felty’s syndrome without a site.
Do not use for
Do not use this code for unspecified Felty’s syndrome, left hip disease, or general rheumatoid arthritis without Felty’s syndrome. Do not assign it when the chart does not identify the right hip.
Coding tip
Verify both the syndrome and the right-sided location in the provider note before coding.
