Embryonic cyst of broad ligament

This code describes a benign, fluid-filled sac that develops from embryonic remnants within the broad ligament of the uterus. These cysts are typically asymptomatic but can occasionally cause pelvic pain or be discovered incidentally during imaging or surgery.

Assign this code when documentation clearly identifies an embryonic cyst located within the broad ligament. This diagnosis is often made via ultrasound, MRI, or during gynecological surgery. Ensure the physician's notes specify "embryonic" or "mesonephric" origin if known, and its location within the broad ligament.

• Differentiate from other broad ligament cysts that are not of embryonic origin (e.g., parovarian cysts, which may have different coding).
• Do not use for ovarian cysts or other adnexal masses; ensure the broad ligament location is explicitly stated.
• Consider additional codes for any associated symptoms (e.g., pelvic pain) or complications if documented.
