Polyp of corpus uteri

This code represents the presence of a benign, often pedunculated or sessile, growth originating from the endometrial lining of the main body of the uterus. These polyps are typically composed of endometrial tissue, glands, and stroma. They can vary in size and may be asymptomatic or cause abnormal uterine bleeding.

Use this code when documentation clearly indicates a diagnosis of an endometrial polyp located specifically within the corpus (body) of the uterus. This diagnosis is often made following hysteroscopy, ultrasound, or endometrial biopsy. Supporting documentation should specify the location of the polyp within the uterine corpus.

• Differentiate from cervical polyps (621.3) or polyps of other uterine segments.
• Ensure the pathology report or operative note explicitly states "corpus uteri" or "endometrial polyp" to support this code.
• If the polyp is found to be malignant upon pathology, a more specific malignancy code would supersede this benign diagnosis.
