Code Description

ICD-10 N83.51 is a billable code used to indicate a diagnosis of torsion of ovary and ovarian pedicle.

Key Diagnostic Point:

Torsion of the ovary and its pedicle is a surgical emergency characterized by the twisting of the ovary around its supporting ligaments, leading to compromised blood flow. This condition can occur in women of any age but is most common in those of reproductive age. Symptoms typically include sudden onset of unilateral abdominal or pelvic pain, nausea, vomiting, and sometimes fever. Physical examination may reveal unilateral adnexal tenderness and a palpable adnexal mass. Diagnosis is often confirmed through imaging studies such as ultrasound, which may show an enlarged, edematous ovary and the absence of venous or arterial flow. Prompt surgical intervention is critical to untwist the ovary and restore blood flow, as prolonged torsion can lead to ovarian necrosis. In some cases, torsion may be associated with underlying conditions such as endometriosis, ovarian cysts, or tumors, which can predispose the ovary to twisting. Understanding the relationship between torsion and other gynecological disorders is essential for accurate diagnosis and management.

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 association with other gynecological disorders.
  • Variability in presentation based on age and underlying conditions.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to document imaging studies used for diagnosis.
  • Lack of clarity on the surgical procedure performed.
  • Misclassification of the condition as a non-emergency.

Frequently Asked Questions

What are the common symptoms of ovarian torsion?

Common symptoms include sudden unilateral pelvic or abdominal pain, nausea, vomiting, and sometimes fever. Physical examination may reveal tenderness and a palpable mass.

How is ovarian torsion diagnosed?

Diagnosis is typically made through imaging studies, particularly ultrasound, which can show an enlarged ovary and lack of blood flow.

What is the treatment for ovarian torsion?

The primary treatment is surgical intervention to untwist the ovary and restore blood flow. In cases of necrosis, oophorectomy may be necessary.

Can ovarian torsion occur in women with endometriosis?

Yes, endometriosis can increase the risk of ovarian torsion due to anatomical changes and the presence of cysts.
