Endometriosis of the pelvic nerves, unspecified

This code signifies the presence of endometrial tissue abnormally located on or infiltrating the pelvic nerves, without further specification of the exact nerve involved. This condition can lead to chronic pelvic pain, dyspareunia, and neurological symptoms such as sciatica or bladder dysfunction, depending on the affected nerves.

Use this code when documentation confirms endometriosis affecting the pelvic nerves, but the specific nerve (e.g., sciatic, pudendal) is not identified. This typically occurs when imaging or surgical findings indicate nerve involvement without precise anatomical localization.

• Ensure documentation explicitly states "pelvic nerves" and "endometriosis."
• If a specific pelvic nerve is identified (e.g., sciatic nerve), use a more precise code from the N80.D subcategory.
• Always sequence this code after the primary diagnosis if the endometriosis is a manifestation of a broader condition.
