Endometrial Cancer Screening, Diagnosis, and Prognosis (CPB 0769, reviewed 2025-10-03)
Summary
Aetna considers endometrial biopsy medically necessary for the diagnostic evaluation of abnormal uterine bleeding in women suspected of having endometrial hyperplasia or endometrial carcinoma, and for endometrial cancer surveillance in women with Lynch syndrome. The endometrial brush (Tao brush) is an acceptable alternative to a suction curette such as the Pipelle for medically necessary sampling. Sentinel lymph node mapping is medically necessary for pathologic evaluation and surgical staging in persons with endometrial cancer and endometrial intraepithelial neoplasia (EIN), while endometrial biopsy for screening and many biomarker and genetic tests for endometrial cancer are experimental, investigational, or unproven.
