Endometriosis of the uterus, unspecified

This code signifies the presence of endometrial tissue growing outside the uterine cavity but specifically within the myometrium (adenomyosis) or on the outer surface of the uterus, without further specification of its exact location or extent. It represents a diagnosis of endometriosis affecting the uterus when the precise anatomical involvement within the uterus is not documented.

Use this code when the provider's documentation clearly states "endometriosis of the uterus" or "uterine endometriosis" without specifying if it's adenomyosis, serosal endometriosis, or other specific uterine sites. This code is appropriate when the diagnostic workup confirms uterine involvement but lacks granular detail regarding the exact location within the uterus.

• Avoid using this code if the documentation specifies adenomyosis (N80.01) or endometriosis of the uterine serosa (N80.02).
• Ensure the medical record supports a diagnosis of endometriosis affecting the uterus.
• Query the provider for more specific anatomical detail if available to allow for a more precise code assignment.
