Code Description

ICD-10 M66.151 is a billable code used to indicate a diagnosis of rupture of synovium, right hip.

Key Diagnostic Point:

Rupture of the synovium in the right hip is a condition characterized by the tearing of the synovial membrane, which lines the joint capsule and produces synovial fluid. This condition can result from acute trauma, chronic overuse, or underlying inflammatory diseases such as rheumatoid arthritis. Clinically, patients may present with localized pain, swelling, and reduced range of motion in the hip joint. The rupture can lead to joint effusion and may be associated with tenosynovitis, where the tendon sheath becomes inflamed. Diagnosis typically involves a thorough clinical examination, imaging studies such as MRI or ultrasound, and sometimes arthroscopy to visualize the joint directly. Treatment options may include conservative management with rest, ice, and anti-inflammatory medications, or surgical intervention to repair the synovium if conservative measures fail. Understanding the underlying causes and associated conditions is crucial for effective management and coding of this diagnosis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic conditions
  • Identifying associated conditions such as tenosynovitis
  • Need for precise documentation of the location and extent of the rupture
  • Variability in treatment approaches based on severity

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the laterality of the condition
  • Lack of imaging or clinical evidence to support the diagnosis
  • Misclassification of the condition as a tendon rupture instead of synovial rupture
