Postmeningococcal arthritis
ICD-10 A39.84 is a billable code used to indicate a diagnosis of postmeningococcal arthritis.
Postmeningococcal arthritis is a rare complication that can occur following meningococcal infection, particularly in cases of meningococcemia. This condition is characterized by the development of arthritis due to the immune response triggered by the meningococcal bacteria (Neisseria meningitidis). The inflammation in the joints can lead to significant pain, swelling, and reduced mobility. Patients may present with acute onset of joint pain, often affecting large joints such as the knees, ankles, and wrists. The pathophysiology involves the deposition of immune complexes in the joints, leading to synovitis and subsequent arthritis. Diagnosis is typically made through clinical evaluation, supported by laboratory tests that may include blood cultures, serology, and imaging studies to assess joint involvement. Treatment usually involves the use of non-steroidal anti-inflammatory drugs (NSAIDs) for pain management, corticosteroids to reduce inflammation, and antibiotics if there is an active infection. Early recognition and management are crucial to prevent long-term joint damage.
Detailed history of joint symptoms, previous infections, and treatment response.
Patients presenting with joint pain post-meningococcal infection.
Need for clear documentation of the relationship between the infection and arthritis.
Comprehensive records of the infection, including lab results and treatment history.
Management of patients with sequelae from meningococcal disease.
Focus on the infectious history and its impact on joint health.
Used when joint swelling requires aspiration for diagnostic or therapeutic purposes.
Document the reason for the procedure, joint involved, and any findings.
Rheumatologists may perform this procedure frequently in managing post-infectious arthritis.
Postmeningococcal arthritis is primarily caused by the immune response to Neisseria meningitidis following an infection, leading to inflammation in the joints.
