Endometriosis of the pelvic brim, unsp side, unsp depth

This code signifies the presence of endometrial tissue outside the uterus, specifically located in the pelvic brim region. This ectopic tissue responds to hormonal changes, leading to inflammation, pain, and potential adhesions. The "unspecified side" and "unspecified depth" indicate that the exact location within the pelvic brim or the extent of tissue invasion is not documented.

Use this code when documentation confirms endometriosis affecting the pelvic brim, but the laterality (left or right) and the depth of invasion (e.g., superficial, deep) are not specified by the provider. This code is appropriate when the diagnostic workup, such as imaging or surgical findings, identifies endometriosis in this anatomical area without further detail.

• Avoid using this code if the laterality (left or right pelvic brim) or depth of endometriosis is clearly documented; instead, select a more specific N80.38- subcategory.
• Ensure the medical record explicitly states "pelvic brim" as the site of endometriosis to support this code.
• Consider sequencing this code after a code for chronic pelvic pain (e.g., R10.2) if that is the primary reason for the encounter and the endometriosis is an underlying cause.
