Torsion of fallopian tube, unspecified side

This code signifies the twisting of a fallopian tube, which can compromise its blood supply and lead to ischemia or necrosis. It represents a gynecological emergency characterized by acute pelvic pain. This diagnosis indicates that the specific side (left or right) of the affected fallopian tube was not documented.

Apply this code when documentation confirms a diagnosis of fallopian tube torsion, but the medical record does not specify whether it occurred on the left or right side. This typically occurs in emergency department settings or during initial diagnostic workups where laterality is not yet definitively determined or recorded.

• Always strive for laterality (left or right) if documented; use this code only when laterality is truly unspecified.
• Do not confuse with ovarian torsion (N83.51- or N83.52-), which involves the ovary, though often both structures are involved.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, especially in acute care settings.
