Felty's syndrome, right knee
ICD-10 M05.061 is a billable code used to indicate a diagnosis of felty's syndrome, right knee.
Felty's syndrome is a rare complication of rheumatoid arthritis characterized by the triad of rheumatoid arthritis, splenomegaly, and neutropenia. The right knee is often involved due to the symmetrical nature of rheumatoid arthritis, leading to synovitis, joint effusion, and pain. Anatomically, the knee joint comprises the femur, tibia, fibula, and patella, with surrounding ligaments and synovial tissue that can become inflamed. Clinically, patients may present with joint swelling, stiffness, and decreased range of motion, particularly in the right knee. The pathophysiology involves autoimmune mechanisms where the immune system mistakenly attacks joint tissues, leading to chronic inflammation and joint damage. Early diagnosis and management are crucial to prevent further complications such as joint deformity and functional impairment.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage, functional assessments to evaluate range of motion, and treatment plans detailing surgical or non-surgical interventions.
Common scenarios include joint injections, arthroscopy for synovitis, or total knee arthroplasty in advanced cases.
Documentation must reflect the severity of joint involvement and any deformities present.
Rheumatologic documentation should include laboratory tests for inflammatory markers (e.g., ESR, CRP), complete blood counts to monitor neutropenia, and assessments of disease activity (e.g., DAS28 score).
Management of Felty's syndrome may involve disease-modifying antirheumatic drugs (DMARDs) and biologics.
Systemic involvement must be documented, including any complications arising from neutropenia.
Functional assessments should evaluate mobility, strength, and the need for assistive devices. Rehabilitation plans must be detailed to address specific limitations.
Rehabilitation may focus on improving joint function and managing pain through physical therapy.
Mobility limitations should be clearly documented, including the impact on daily activities.
Used for managing joint effusion in the right knee due to Felty's syndrome.
Document the indication for the procedure, including joint involvement and any prior treatments.
Orthopedic considerations for joint health and rheumatologic implications of the procedure.
Key symptoms include joint pain and swelling, particularly in the knees, fatigue, recurrent infections due to neutropenia, and splenomegaly. It is important to document these symptoms accurately for proper coding.
