Torsion of left fallopian tube

This code signifies a twisting of the left fallopian tube, which can lead to obstructed blood flow and potential tissue damage (ischemia or necrosis). It is an acute gynecological emergency characterized by sudden onset of severe unilateral pelvic pain.

Use this code when documentation clearly indicates a diagnosis of torsion specifically affecting the left fallopian tube. This diagnosis is typically confirmed through imaging studies (e.g., ultrasound with Doppler) and/or surgical exploration.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Do not confuse with ovarian torsion (N83.51-) or torsion of both fallopian tubes (N83.53).
• Code any associated complications, such as necrosis or infection, as additional diagnoses.
