Endometrial hyperplasia, unspecified

This code represents an overgrowth of the endometrial lining of the uterus without further specification of its histological characteristics. It indicates an abnormal proliferation of endometrial glands and stroma, which can be a precursor to endometrial carcinoma. The "unspecified" nature means the specific type of hyperplasia (e.g., simple, complex, with or without atypia) is not documented.

Use this code when medical record documentation indicates endometrial hyperplasia but lacks details regarding its specific classification or presence of atypia. This is appropriate when a pathology report confirms hyperplasia but does not provide further subtyping, or when a clinician diagnoses hyperplasia without a definitive pathological classification available at the time of coding.

• Avoid using this code if the pathology report specifies the type of hyperplasia (e.g., simple, complex, atypical); instead, use the more specific N85.01-N85.03 codes.
• Ensure documentation clearly states "endometrial hyperplasia" without further detail to support this unspecified code.
• If atypical hyperplasia is documented, a more specific code reflecting the atypical nature should be assigned due to its higher malignant potential.
