Code Description

ICD-10 N83.512 is a billable code used to indicate a diagnosis of torsion of left ovary and ovarian pedicle.

Key Diagnostic Point:

Torsion of the left 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 result in ischemia and necrosis of the ovarian tissue if not promptly diagnosed and treated. Symptoms typically include sudden onset of unilateral pelvic pain, nausea, vomiting, and sometimes fever. Physical examination may reveal unilateral adnexal tenderness and a palpable adnexal mass. Imaging studies, particularly ultrasound with Doppler flow studies, are crucial for diagnosis, as they can help visualize the twisted pedicle and assess blood flow to the ovary. Torsion can occur in the presence of ovarian cysts, tumors, or anatomical abnormalities, and it may be associated with conditions such as endometriosis, which can alter the normal anatomy of the pelvic organs. Timely surgical intervention is essential to untwist the ovary and restore blood flow, and in some cases, oophorectomy may be necessary if the ovary is necrotic. Understanding the relationship between torsion and other gynecological disorders, such as endometriosis and ovarian cysts, is vital 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 for associated conditions like endometriosis or cysts.
  • Variability in presentation and symptoms among patients.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to document imaging results that support diagnosis.
  • Misclassification of torsion as a less severe condition.
  • Lack of clarity on surgical interventions performed.
