Code Description

ICD-10 N83.511 is a billable code used to indicate a diagnosis of torsion of right ovary and ovarian pedicle.

Key Diagnostic Point:

Torsion of the right ovary and its pedicle is a surgical emergency characterized by the twisting of the ovarian tissue around its vascular supply, leading to compromised blood flow. This condition often presents with acute abdominal or pelvic pain, nausea, and vomiting. It can occur in women of any age but is most common in those of reproductive age. Risk factors include ovarian cysts, pregnancy, and anatomical abnormalities. Diagnosis is typically made through clinical evaluation and imaging studies, such as ultrasound, which may reveal an enlarged, edematous ovary with decreased or absent blood flow. Prompt surgical intervention is crucial to salvage the affected ovary and prevent complications such as necrosis or peritonitis. The condition can be associated with other gynecological disorders, including endometriosis, which may complicate the clinical picture, and it is essential for coders to understand the nuances of these associations for accurate coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between torsion and other ovarian disorders such as cysts or tumors.
  • Understanding the acute nature of the condition and its urgency.
  • The need for precise documentation of symptoms and imaging findings.
  • Potential overlap with other gynecological conditions like endometriosis.

Audit Risk Factors

  • Inadequate documentation of acute symptoms.
  • Failure to document imaging results that support the diagnosis.
  • Misclassification of the condition as a non-urgent issue.
  • Lack of clarity in surgical notes regarding the procedure performed.
