Felty's syndrome, unspecified ankle and foot
ICD-10 M05.079 is a billable code used to indicate a diagnosis of felty's syndrome, unspecified ankle and foot.
Felty's syndrome is a rare complication of rheumatoid arthritis characterized by the triad of rheumatoid arthritis, splenomegaly, and neutropenia. In the context of the ankle and foot, patients may experience significant joint inflammation, pain, and deformity due to the underlying autoimmune process. Anatomically, the ankle joint comprises the tibia, fibula, and talus, while the foot consists of multiple bones including the metatarsals and phalanges. The inflammatory process can lead to synovitis, erosion of joint surfaces, and subsequent functional limitations. Clinically, patients may present with swelling, tenderness, and reduced range of motion in the affected joints, impacting their mobility and quality of life. The pathophysiology involves immune-mediated damage to the synovial membrane, leading to chronic inflammation and joint destruction.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage, functional assessments to evaluate mobility, and detailed notes on joint examination findings.
Patients may require surgical intervention for joint deformities or severe pain management, including arthroplasty or joint fusion.
Orthopedic considerations include the assessment of joint stability and the potential need for reconstructive surgery.
Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP), neutrophil counts, and assessments of disease activity (e.g., DAS28).
Management of Felty's syndrome may involve immunosuppressive therapy and monitoring for complications such as infections due to neutropenia.
Systemic involvement, including splenomegaly and its effects on blood counts, must be documented.
Functional assessments should evaluate the patient's ability to perform daily activities and the need for assistive devices.
Rehabilitation may focus on restoring mobility and strength, with tailored exercise programs.
Documentation should address mobility limitations and the impact on the patient's quality of life.
Used for follow-up visits for management of Felty's syndrome.
Documentation must include history, examination findings, and treatment plan.
Rheumatology considerations include monitoring disease activity and adjusting treatment.
Used for joint injections in patients with severe inflammation.
Indicate the joint involved and the reason for the procedure.
Orthopedic considerations include assessing joint effusion.
Common symptoms include joint pain and swelling, recurrent infections due to neutropenia, and splenomegaly. Patients may also experience fatigue and systemic symptoms related to rheumatoid arthritis.
