Code Description

ICD-10 M67.349 is a billable code used to indicate a diagnosis of transient synovitis, unspecified hand.

Key Diagnostic Point:

Transient synovitis is a temporary inflammation of the synovial membrane, which lines the joints and tendons. In the case of the hand, this condition can lead to pain, swelling, and limited range of motion. It is often seen in children and can be triggered by trauma, infection, or autoimmune conditions. The inflammation can cause the synovial fluid to accumulate, leading to joint effusion. Diagnosis typically involves clinical examination and imaging studies, such as ultrasound or MRI, to assess the extent of inflammation and rule out other conditions like tenosynovitis or tendon ruptures. Treatment usually includes rest, ice, and non-steroidal anti-inflammatory drugs (NSAIDs). In some cases, corticosteroid injections may be considered to reduce inflammation. Surgical intervention is rare but may be necessary if conservative management fails or if there is a significant underlying structural issue. Accurate coding is essential for proper reimbursement and to reflect the patient's clinical status.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and symptoms
  • Differentiation from other synovial disorders
  • Potential overlap with tenosynovitis and tendon injuries
  • Need for precise documentation to support the diagnosis

Audit Risk Factors

  • Insufficient documentation of clinical findings
  • Failure to specify the affected joint or tendon
  • Inadequate justification for imaging studies
  • Misclassification with chronic synovitis or other conditions
