Code Description

ICD-10 M67.331 is a billable code used to indicate a diagnosis of transient synovitis, right wrist.

Key Diagnostic Point:

Transient synovitis of the wrist is characterized by inflammation of the synovial membrane, which can lead to joint swelling, pain, and limited range of motion. This condition is often seen in children and young adults and can be triggered by trauma, overuse, or infection. In the right wrist, transient synovitis may present with localized tenderness, warmth, and swelling, particularly after physical activity. Diagnosis typically involves a thorough clinical examination, imaging studies such as ultrasound or MRI, and sometimes aspiration of the joint to rule out infection or other underlying conditions. Treatment usually includes rest, ice, non-steroidal anti-inflammatory drugs (NSAIDs), and physical therapy. In some cases, corticosteroid injections may be considered to reduce inflammation. The prognosis is generally favorable, with most patients recovering fully without long-term complications. However, it is essential to monitor for any signs of chronic synovitis or joint damage, especially if symptoms persist or worsen.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating transient synovitis from other synovial disorders.
  • Need for precise documentation of symptoms and treatment.
  • Potential overlap with codes for tenosynovitis and other wrist conditions.
  • Variability in clinical presentation among different patient populations.

Audit Risk Factors

  • Inadequate documentation of clinical findings.
  • Failure to specify laterality (right wrist).
  • Misclassification as a chronic condition.
  • Lack of imaging or treatment documentation.

Frequently Asked Questions

What are the common causes of transient synovitis?

Common causes include trauma, overuse, and sometimes viral infections. It is essential to evaluate the patient's history and activity level to determine the underlying cause.

How is transient synovitis treated?

Treatment typically involves rest, ice, NSAIDs for pain relief, and physical therapy. In some cases, corticosteroid injections may be used to reduce inflammation.
