Other reactive arthropathies, left knee
ICD-10 M02.862 is a billable code used to indicate a diagnosis of other reactive arthropathies, left knee.
Reactive arthropathies are a group of inflammatory joint conditions that occur secondary to an infection elsewhere in the body, often involving the genitourinary or gastrointestinal systems. The left knee, as a major weight-bearing joint, is particularly susceptible to these conditions due to its complex anatomy, which includes the femur, tibia, fibula, patella, and surrounding ligaments and cartilage. Clinically, patients may present with swelling, pain, and limited range of motion in the left knee, often following an infection. The pathophysiology involves an immune-mediated response where the body mistakenly attacks its own joint tissues, leading to inflammation and joint damage. Symptoms may include joint stiffness, tenderness, and effusion, which can significantly impact mobility and daily activities.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint integrity and functional assessments to evaluate range of motion and strength.
Patients may present with acute knee pain following a recent gastrointestinal infection, requiring evaluation for potential surgical intervention if conservative management fails.
Documentation should detail the severity of joint involvement and any associated ligamentous injuries.
Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity.
Patients may have a history of reactive arthritis following a sexually transmitted infection, necessitating a comprehensive evaluation of joint and systemic symptoms.
Consideration of potential systemic involvement, such as skin or ocular manifestations, is crucial.
Functional assessments should evaluate mobility, strength, and the need for assistive devices to aid rehabilitation.
Patients may require physical therapy to restore function after an episode of reactive arthritis.
Focus on mobility limitations and the impact on daily living activities.
Used for patients with significant effusion in the left knee due to reactive arthropathy.
Document the indication for the procedure, including joint effusion and pain severity.
Orthopedic evaluation may be necessary to assess the need for further intervention.
Reactive arthropathies are often triggered by infections, particularly in the genitourinary or gastrointestinal systems. Common pathogens include Chlamydia, Salmonella, and Yersinia.
