Torsion of right fallopian tube

This code signifies the twisting of the right fallopian tube, which can compromise its blood supply and lead to ischemia or necrosis. This acute gynecological emergency often presents with sudden, severe unilateral lower abdominal pain.

Apply this code when documentation clearly indicates a diagnosis of torsion specifically affecting the right fallopian tube. Supporting documentation typically includes operative reports detailing the untwisting or removal of the right adnexa, or imaging reports confirming the diagnosis.

• Ensure laterality is explicitly documented as "right" to avoid unspecified coding.
• Differentiate from ovarian torsion (N83.51-) or torsion of both fallopian tubes (N83.53).
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
