Torsion of ovary, ovarian pedicle and fallopian tube

This code signifies the twisting of an ovary, its supporting pedicle (the vascular and ligamentous structures), and/or the fallopian tube. This twisting compromises the blood supply to these organs, leading to acute pain and potential tissue necrosis if not promptly addressed. It is a gynecological emergency requiring urgent medical intervention.

Apply this code when documentation clearly indicates a diagnosis of ovarian torsion, fallopian tube torsion, or combined adnexal torsion. This diagnosis is typically made based on clinical presentation (sudden onset severe pelvic pain, nausea/vomiting), physical examination, and confirmed by imaging studies such as ultrasound with Doppler flow.

• Specify laterality (left, right, or bilateral) if documented, using the appropriate sub-codes.
• Do not use this code for ovarian cysts or masses without documented torsion.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially for surgical intervention.
