Other reactive arthropathies, right knee
ICD-10 M02.861 is a billable code used to indicate a diagnosis of other reactive arthropathies, right knee.
Reactive arthropathies are inflammatory joint conditions that arise secondary to infections or other systemic diseases, often presenting with joint pain, swelling, and stiffness. The right knee, as a hinge joint, is particularly susceptible to these conditions due to its weight-bearing function and range of motion. Anatomically, the knee comprises the femur, tibia, fibula, and patella, with ligaments, tendons, and cartilage providing stability and mobility. Pathophysiologically, reactive arthropathies may occur following infections such as urethritis or gastroenteritis, leading to an immune-mediated response that affects the synovial membrane and joint structures. Clinically, patients may present with unilateral knee pain, effusion, and decreased range of motion, often exacerbated by activity. Diagnosis typically involves clinical evaluation, imaging studies, and laboratory tests to rule out other causes of arthritis.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint integrity and functional assessments to evaluate mobility and pain levels.
Common scenarios include post-infectious arthritis following a urinary tract infection or gastrointestinal infection, requiring surgical intervention if conservative management fails.
Joint-specific considerations include assessing for ligamentous injuries or meniscal tears that may coexist with reactive arthropathies.
Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and disease activity assessments to monitor progression.
Autoimmune conditions such as reactive arthritis following Chlamydia infection, necessitating a comprehensive treatment plan.
Systemic involvement may require monitoring for extra-articular manifestations, such as skin or eye symptoms.
Functional assessments should evaluate the patient's ability to perform daily activities and any need for assistive devices.
Rehabilitation scenarios may include post-arthroscopy recovery or physical therapy for joint mobilization.
Mobility limitations should be documented, including the need for gait training or adaptive equipment.
Used for joint effusion management in reactive arthropathies.
Document the reason for the procedure, joint involved, and any findings during aspiration.
Orthopedic and rheumatologic considerations for joint management.
Common causes include infections such as Chlamydia, gastrointestinal infections, and other systemic inflammatory conditions that trigger an immune response affecting the joints.
