Code Description

ICD-10 N83.5 is a billable code used to indicate a diagnosis of torsion of ovary, ovarian pedicle and fallopian tube.

Key Diagnostic Point:

Torsion of the ovary, ovarian pedicle, and fallopian tube is a surgical emergency characterized by the twisting of the ovary and its supporting structures, leading to compromised blood flow. This condition can result in ischemia and necrosis of the affected ovary if not promptly diagnosed and treated. Torsion often presents with sudden onset abdominal or pelvic pain, nausea, and vomiting. It is more common in women of reproductive age and can occur in the presence of ovarian cysts, masses, or anatomical abnormalities. The diagnosis is typically confirmed through imaging studies such as ultrasound, which may show an enlarged, edematous ovary and the absence of venous flow. Surgical intervention is usually required to untwist the affected structures and assess for viability. In some cases, the affected ovary may need to be removed if necrosis has occurred. Early recognition and treatment are crucial to preserve ovarian function and prevent complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between torsion and other acute abdominal conditions.
  • Need for imaging studies to confirm diagnosis.
  • Potential for concurrent conditions such as endometriosis or ovarian cysts.
  • Variability in presentation based on age and underlying health.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to document imaging results.
  • Incorrect coding of associated procedures.
  • Lack of clarity on the urgency of the condition.
