Postinfective and reactive arthropathies
Chapter 13:Diseases of the musculoskeletal system
ICD-10 M02 is a billable code used to indicate a diagnosis of postinfective and reactive arthropathies.
Postinfective and reactive arthropathies encompass a group of inflammatory joint disorders that occur following an infection or as a reaction to an infectious agent. These conditions can affect any joint in the body, including the knees, hips, and hands, leading to pain, swelling, and reduced mobility. The pathophysiology often involves an autoimmune response triggered by the infection, where the immune system mistakenly attacks the joint tissues. Clinically, patients may present with acute onset of joint pain, stiffness, and swelling, often following a recent infection such as gastroenteritis or a genitourinary infection. Anatomically, the synovial joints are primarily affected, where inflammation can lead to synovitis, erosion of cartilage, and potential joint deformities if left untreated. Early diagnosis and intervention are crucial to prevent long-term joint damage.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage and functional assessments to evaluate range of motion.
Patients presenting with acute knee pain following a recent gastrointestinal infection requiring joint aspiration or corticosteroid injections.
Documentation must specify which joints are affected and the severity of the condition to guide treatment options.
Rheumatologic documentation should include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity.
Patients with a history of reactive arthritis following a urinary tract infection presenting with joint swelling and systemic symptoms.
Consideration of systemic involvement, such as skin or eye symptoms, which may indicate a broader autoimmune process.
Functional assessments should evaluate mobility limitations and the need for assistive devices.
Patients undergoing rehabilitation for joint stiffness and pain management post-infection.
Focus on mobility limitations and the impact on daily activities to tailor rehabilitation programs.
Used for joint swelling and pain management in reactive arthropathies.
Document the joint involved, the reason for the procedure, and any fluid analysis results.
Orthopedic considerations for joint stability and rehabilitation post-procedure.
Common causes include infections such as Chlamydia, Salmonella, and viral infections like parvovirus B19. These infections can trigger an inflammatory response in the joints, leading to pain and swelling.
