Benign endometrial hyperplasia.Endometrial hyperplasia without atypia.

Use this code when the diagnosis of benign endometrial hyperplasia has been confirmed by appropriate diagnostic methods.Do not use this code if atypia is present. For atypical hyperplasia, use N85.02 (Endometrial intraepithelial neoplasia).

Medical necessity for the diagnosis and treatment of benign endometrial hyperplasia is based on the patient's symptoms, the risk of progression to endometrial cancer, and the impact on the patient's quality of life.

Diagnosis and management of benign endometrial hyperplasia typically falls under the purview of gynecologists or obstetrician-gynecologists. They are responsible for evaluating patients, performing diagnostic procedures like endometrial biopsy or hysteroscopy, and recommending appropriate treatment strategies.

Benign endometrial hyperplasia, also known as simple or complex endometrial hyperplasia without atypia. This condition involves the overgrowth of the uterine lining (endometrium) but does not show precancerous changes (atypia).

An endometrial biopsy reveals benign endometrial hyperplasia., A 55-year-old postmenopausal woman experiences unexpected vaginal bleeding.
