Transient synovitis, left knee
ICD-10 M67.362 is a billable code used to indicate a diagnosis of transient synovitis, left knee.
Transient synovitis of the left knee is a benign inflammatory condition characterized by the temporary inflammation of the synovial membrane, which lines the knee joint. This condition is most commonly seen in children and adolescents, often presenting with acute knee pain, swelling, and limited range of motion. The etiology is frequently idiopathic, but it can also be associated with recent viral infections or trauma. Diagnosis is primarily clinical, supported by imaging studies such as ultrasound or MRI, which may reveal joint effusion and synovial thickening. Treatment typically involves rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and in some cases, aspiration of the joint. The prognosis is generally favorable, with most patients experiencing complete resolution of symptoms within a few weeks. However, it is crucial to differentiate transient synovitis from more serious conditions such as septic arthritis or osteomyelitis, which require more aggressive intervention.
Detailed history of present illness, physical examination findings, and any imaging studies performed.
Acute knee pain in a child following a viral illness or minor trauma.
Ensure to document the duration of symptoms and any response to initial treatment.
Comprehensive assessment including range of motion, joint stability, and any surgical interventions if applicable.
Evaluation of knee pain with suspected transient synovitis versus other orthopedic conditions.
Document any differential diagnoses considered and rationale for treatment decisions.
Used when joint effusion is present and aspiration is performed.
Document indication for aspiration, findings, and volume of fluid removed.
Orthopedic specialists should ensure proper coding based on the procedure performed.
The primary treatment includes rest, NSAIDs for pain relief, and sometimes aspiration of the joint if effusion is significant.
Transient synovitis typically presents with normal laboratory findings, while septic arthritis shows elevated inflammatory markers and may require joint aspiration for culture.
