Endometriosis of bilateral pelvic brim, unspecified depth

This code describes the presence of endometrial-like tissue located on both sides of the pelvic brim, the superior opening of the true pelvis. The depth of infiltration of this endometrial tissue into the surrounding structures is not specified in the medical record. This is a chronic gynecological condition that can cause pain and infertility.

Use this code when documentation explicitly states endometriosis affecting both the left and right pelvic brim, without further detail regarding the extent of tissue invasion. This code is appropriate when a surgeon or radiologist identifies endometriosis in this specific bilateral location but does not quantify or describe the depth of involvement.

• Ensure documentation specifies bilateral involvement of the pelvic brim.
• Do not use if the depth of infiltration (e.g., superficial, deep) is documented; a more specific code would be required.
• Consider sequencing with codes for associated symptoms (e.g., chronic pelvic pain) or complications.
