Torsion of right ovary and ovarian pedicle

This code signifies the twisting of the right ovary and its supporting vascular and ligamentous structures, leading to compromised blood flow. This acute gynecological emergency can cause severe abdominal pain, nausea, and vomiting due to ischemia and potential necrosis of the ovarian tissue. Prompt diagnosis and intervention are crucial to preserve ovarian viability.

Assign this code for patients presenting with clinical signs and symptoms consistent with ovarian torsion, specifically affecting the right adnexa. Documentation should clearly state "torsion of right ovary" or "right ovarian torsion," often confirmed by imaging studies like ultrasound or surgical findings.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Do not confuse with ovarian cysts (N83.2-) or other adnexal masses unless torsion is also present.
• Sequence this code as the primary diagnosis when ovarian torsion is the reason for the encounter and treatment.
