Embryonic cyst of fallopian tube

This code identifies a congenital anomaly characterized by the presence of a fluid-filled sac originating from embryonic remnants within the fallopian tube. These cysts are typically benign and may be discovered incidentally during imaging or surgical procedures.

Assign this code when documentation clearly indicates an embryonic or congenital cyst of the fallopian tube. This diagnosis is often made following imaging studies such as ultrasound or MRI, or confirmed during laparoscopic exploration or salpingectomy.

• Differentiate from acquired fallopian tube cysts (e.g., hydrosalpinx), which have different etiologies and codes.
• Ensure the documentation specifies "embryonic" or "congenital" origin to support this specific code.
• If the cyst is symptomatic or requires intervention, code the associated symptoms or procedure in addition to this diagnosis.
