Transient synovitis, unspecified knee
ICD-10 M67.369 is a billable code used to indicate a diagnosis of transient synovitis, unspecified knee.
Transient synovitis of the knee is a benign inflammatory condition characterized by the temporary swelling of the synovial membrane, which lines the knee joint. This condition is most commonly seen in children and can present with symptoms such as knee pain, swelling, and limited range of motion. The etiology is often idiopathic, but it may follow a viral infection or minor trauma. Diagnosis is typically made through clinical evaluation and imaging studies, such as ultrasound or MRI, which can help rule out other conditions like septic arthritis or osteomyelitis. Treatment usually involves rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and in some cases, aspiration of the joint to relieve pressure. The prognosis is generally good, with most patients recovering fully without long-term complications. However, it is crucial to differentiate transient synovitis from more serious conditions that may require surgical intervention, such as septic arthritis or significant joint damage.
Detailed history of symptoms, physical examination findings, and any imaging results.
A child presenting with knee pain after a viral illness, with swelling and limited range of motion.
Consideration of differential diagnoses such as septic arthritis, especially in febrile patients.
Comprehensive assessment of joint function, imaging studies, and treatment plans.
An adult patient with knee pain and swelling following minor trauma, requiring evaluation for potential surgical intervention.
Documentation must clearly differentiate transient synovitis from chronic conditions or acute injuries.
Used when joint effusion is present and needs to be drained.
Document the indication for aspiration, the amount of fluid removed, and any findings.
Orthopedic specialists should ensure that the procedure is justified based on clinical findings.
The primary treatment includes rest, NSAIDs for pain relief, and in some cases, aspiration of the joint to relieve pressure.
Transient synovitis typically presents without fever and has negative cultures, while septic arthritis usually presents with fever and positive cultures.
