Postdysenteric arthropathy, right knee
ICD-10 M02.161 is a billable code used to indicate a diagnosis of postdysenteric arthropathy, right knee.
Postdysenteric arthropathy refers to a type of reactive arthritis that occurs following an episode of dysentery, typically caused by bacterial infections such as Shigella or Salmonella. This condition primarily affects the joints, with the right knee being a common site of involvement. Anatomically, the knee joint consists of the femur, tibia, fibula, and patella, surrounded by ligaments, cartilage, and synovial fluid. The pathophysiology involves an immune-mediated response triggered by the infection, leading to inflammation of the synovial membrane and subsequent joint pain, swelling, and stiffness. Clinically, patients may present with acute onset of knee pain, swelling, and reduced range of motion, often following gastrointestinal symptoms. The condition may also be associated with systemic symptoms such as fever and malaise, and it can lead to chronic joint issues if not properly managed.
Orthopedic documentation should include imaging studies (e.g., X-rays, MRI) to assess joint integrity, functional assessments to evaluate range of motion, and any surgical notes if interventions are performed.
Common scenarios include acute knee pain following a gastrointestinal infection, evaluation for potential arthroscopic intervention, or management of chronic knee pain due to postdysenteric changes.
Joint-specific considerations include assessing for effusion, ligament stability, and potential for surgical intervention if conservative management fails.
Rheumatologic documentation should include laboratory tests for inflammatory markers (e.g., ESR, CRP), patient history of gastrointestinal infections, and assessments of disease activity.
Autoimmune and inflammatory scenarios may involve distinguishing postdysenteric arthropathy from other forms of reactive arthritis or inflammatory arthritis.
Systemic involvement may need to be documented, especially if there are signs of other joint or organ involvement.
Functional assessments should evaluate mobility, pain levels, and the need for assistive devices or rehabilitation services.
Rehabilitation scenarios may include post-surgical recovery or conservative management of chronic knee pain with physical therapy.
Mobility limitations should be documented, including the impact on daily activities and the need for adaptive strategies.
Used for joint effusion management in postdysenteric arthropathy.
Document the reason for aspiration, joint involved, and any therapeutic injections performed.
Orthopedic considerations include assessing joint stability and potential for surgical intervention.
Documenting the infectious history is crucial as it establishes the etiology of the arthropathy, differentiating it from other forms of arthritis and ensuring appropriate management and coding.
