Endometriosis of bilateral pelvic sidewall, unsp depth

This code signifies the presence of endometrial-like tissue on both the left and right pelvic sidewalls. This condition is a form of endometriosis where the ectopic tissue is located on the lateral walls of the pelvis, but the extent or depth of infiltration into the tissue is not specified.

Use this code when documentation clearly indicates endometriosis affecting both pelvic sidewalls, and the physician has not specified the depth of involvement (e.g., superficial vs. deep infiltrating). This code is appropriate when the laterality is bilateral, and no further detail regarding the lesion's penetration is provided.

• Ensure documentation explicitly states "bilateral" involvement of the pelvic sidewalls.
• Avoid using this code if the depth of endometriosis (e.g., superficial, deep infiltrating) is specified; instead, select a more specific code.
• Consider sequencing this code after any codes for primary infertility if endometriosis is identified as a contributing factor.
