Code Description

ICD-10 N83.529 is a billable code used to indicate a diagnosis of torsion of fallopian tube, unspecified side.

Key Diagnostic Point:

Torsion of the fallopian tube is a condition characterized by the twisting of the fallopian tube, which can lead to obstruction of blood flow and subsequent ischemia. This condition may present with acute abdominal or pelvic pain, often accompanied by nausea and vomiting. The torsion can occur on either side, but in this case, it is unspecified. It is crucial to differentiate torsion from other conditions such as ectopic pregnancy, ovarian cyst rupture, or pelvic inflammatory disease, as the management and implications differ significantly. Diagnosis typically involves imaging studies, such as ultrasound or CT scans, to visualize the affected area and assess blood flow. 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. The condition can be associated with other gynecological disorders, including endometriosis, which may predispose individuals to torsion due to adhesions or abnormal pelvic anatomy.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other acute abdominal conditions
  • Need for imaging studies to confirm diagnosis
  • Potential for surgical intervention and associated coding
  • Unspecified side complicates documentation

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify the side of torsion
  • Lack of imaging results in the medical record
  • Improper linkage between diagnosis and surgical procedures

Frequently Asked Questions

What should I document to support the use of N83.529?

Document the patient's symptoms, imaging results, and any surgical findings. Ensure that the side of torsion is clearly stated if known, and include any relevant history such as endometriosis or previous surgeries.
