Code Description

ICD-10 M67.351 is a billable code used to indicate a diagnosis of transient synovitis, right hip.

Key Diagnostic Point:

Transient synovitis of the hip is a benign inflammatory condition characterized by the temporary swelling of the synovial membrane in the hip joint. It primarily affects children, particularly those aged 3 to 10 years, and is often associated with a preceding viral infection or trauma. Clinically, patients present with hip pain, limping, and reduced range of motion. The condition is self-limiting, typically resolving within a few weeks, but it can mimic more serious conditions such as septic arthritis or osteomyelitis. Diagnosis is usually made through clinical evaluation and imaging studies, such as ultrasound or MRI, which can reveal joint effusion. Treatment is generally conservative, involving rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy. In rare cases, aspiration of the joint may be necessary to relieve symptoms. Understanding transient synovitis is crucial for differentiating it from other hip disorders, particularly in pediatric populations, to avoid unnecessary invasive procedures.

Complexity Factors

  • Differentiating from septic arthritis and other hip disorders
  • Age-specific presentation and management
  • Variability in clinical presentation
  • Need for imaging studies for accurate diagnosis

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify laterality
  • Misdiagnosis leading to incorrect coding
  • Lack of follow-up documentation
