Felty's syndrome
ICD-10 M05.0 is a billable code used to indicate a diagnosis of felty's syndrome.
Felty's syndrome is a rare autoimmune disorder characterized by the triad of rheumatoid arthritis (RA), splenomegaly, and neutropenia. It primarily affects the musculoskeletal system, leading to joint inflammation, pain, and deformities. The pathophysiology involves an abnormal immune response where the body attacks its own tissues, particularly the synovial membranes of joints, resulting in chronic inflammation. Anatomically, the condition impacts the joints, particularly the hands, wrists, and knees, leading to significant functional limitations. Patients may experience joint swelling, stiffness, and reduced range of motion, which can severely affect daily activities. The splenomegaly can lead to hypersplenism, further complicating the clinical picture with increased risk of infections due to neutropenia. Clinically, patients present with symptoms of RA, including morning stiffness, fatigue, and systemic manifestations such as fever and weight loss. Diagnosis is often confirmed through serological tests for rheumatoid factor and anti-citrullinated protein antibodies, alongside clinical evaluation.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage and functional assessments to evaluate mobility limitations.
Common scenarios include surgical interventions for joint deformities or arthroplasties due to severe RA.
Joint-specific considerations include documenting the extent of joint damage and functional limitations affecting mobility.
Rheumatologic documentation must include inflammation markers (ESR, CRP) and disease activity scores (DAS28) to assess the severity of RA.
Autoimmune scenarios often involve managing flare-ups and adjusting DMARD therapy based on disease progression.
Systemic involvement must be documented, including any complications arising from neutropenia.
Functional assessments should evaluate the patient's ability to perform activities of daily living and the need for assistive devices.
Rehabilitation scenarios may include physical therapy to improve joint function and mobility.
Mobility limitations should be documented, including the impact on the patient's quality of life.
Used for follow-up visits to manage Felty's syndrome and associated complications.
Documentation must include history, examination findings, and management plan.
Rheumatology considerations include monitoring disease activity and adjusting treatment.
Key features include the presence of rheumatoid arthritis, documented splenomegaly, and neutropenia. Additionally, any joint involvement and functional limitations should be clearly noted to support accurate coding.
