Postimmunization arthropathy, unspecified knee
ICD-10 M02.269 is a billable code used to indicate a diagnosis of postimmunization arthropathy, unspecified knee.
Postimmunization arthropathy refers to joint pain and inflammation that occurs following vaccination. In the case of the knee, this condition can manifest as swelling, stiffness, and pain, which may limit the range of motion and functional capacity of the joint. Anatomically, the knee is a complex hinge joint composed of the femur, tibia, fibula, and patella, surrounded by ligaments, tendons, and synovial fluid. The pathophysiology involves an immune-mediated response triggered by the vaccine, leading to synovitis or inflammation of the synovial membrane. Clinically, patients may present with localized pain, tenderness, and swelling around the knee, often exacerbated by movement. The onset of symptoms can vary, typically occurring within days to weeks post-vaccination. Diagnosis is primarily clinical, supported by patient history and physical examination, and may include imaging studies to rule out other causes of knee pain.
Orthopedic documentation should include imaging studies (e.g., X-rays, MRIs) to assess joint integrity, as well as functional assessments to evaluate the impact on mobility.
Common scenarios include post-vaccination knee pain in patients with a history of joint issues or those undergoing orthopedic procedures.
Joint-specific considerations include the need for detailed documentation of swelling, range of motion, and any surgical interventions if required.
Rheumatologic documentation should include laboratory tests for inflammation markers (e.g., ESR, CRP) and assessments of disease activity.
Scenarios may involve patients with autoimmune conditions who experience exacerbation of symptoms post-vaccination.
Consideration of systemic involvement and monitoring for potential progression of underlying rheumatologic diseases.
Functional assessments should focus on mobility limitations, pain levels, and rehabilitation needs.
Rehabilitation scenarios may include physical therapy interventions aimed at restoring knee function and mobility.
Documentation should address the need for assistive devices or modifications to daily activities.
Used for follow-up visits to assess knee pain post-vaccination.
Documentation must include history of present illness, review of systems, and physical examination findings.
Orthopedic or rheumatologic considerations for ongoing management.
Documentation should include the patient's vaccination history, onset and duration of symptoms, physical examination findings, and any imaging or laboratory results that support the diagnosis.
