Benign endometrial hyperplasia

This code represents a non-cancerous overgrowth of the endometrial lining of the uterus. It is characterized by an increase in the number of endometrial glands and stroma without cellular atypia. This condition can lead to abnormal uterine bleeding.

Use this code when documentation specifies benign endometrial hyperplasia without any mention of atypia. This diagnosis is often made following endometrial biopsy or D&C. Supporting documentation should clearly state "benign" or "simple" hyperplasia.

• Do not use this code if the pathology report indicates atypical hyperplasia; refer to codes in category N85.02.
• Distinguish carefully between benign endometrial hyperplasia and endometrial polyps (N84.0).
• Ensure the documentation specifies the absence of atypia to accurately assign this code.
