Code Description

ICD-10 N83.522 is a billable code used to indicate a diagnosis of torsion of left fallopian tube.

Key Diagnostic Point:

Torsion of the fallopian tube occurs when the tube twists around itself, compromising its blood supply. This condition can lead to ischemia and necrosis of the affected tube if not promptly diagnosed and treated. Torsion of the left fallopian tube is often associated with acute abdominal pain, which may be unilateral and can radiate to the lower back or thigh. Patients may present with nausea, vomiting, and signs of peritoneal irritation. The condition can be idiopathic or associated with underlying factors such as pelvic masses, endometriosis, or anatomical abnormalities. In women with endometriosis, adhesions can contribute to the risk of torsion by tethering the fallopian tube to surrounding structures. Additionally, conditions like ovarian cysts or tumors can increase the likelihood of torsion due to their mass effect. Diagnosis typically involves imaging studies, such as ultrasound, to assess blood flow and rule out other conditions like ectopic pregnancy or ovarian torsion. Surgical intervention is often required to untwist the tube and restore blood flow, and in some cases, removal of the affected tube may be necessary if necrosis has occurred.

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 ovarian disorders.
  • Variability in presentation and symptoms among patients.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to document imaging results that support the diagnosis.
  • Lack of clarity regarding associated conditions like endometriosis.
  • Improper coding of surgical procedures performed.
