Endometriosis of pelvic sidewall, unsp side, unsp depth

This code describes the presence of endometrial-like tissue growing on the pelvic sidewall, which is the inner lining of the bony pelvis. This condition can cause chronic pelvic pain, dyspareunia, and infertility, and its severity can vary. The "unspecified side" and "unspecified depth" indicate that the exact location (left or right) and the extent of tissue infiltration are not documented.

Use this code when documentation confirms endometriosis involving the pelvic sidewall, but the specific 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 pelvic sidewall involvement without further detail.

• Avoid using this code if the laterality (left or right pelvic sidewall) is documented; instead, select a more specific code from the N80.35- subcategory.
• Do not use this code if the depth of endometriosis is specified (e.g., superficial, deep); look for more precise codes if available.
• Always review the operative report or pathology findings for more specific details regarding the location and extent of endometriosis to ensure the most accurate code assignment.
