Endometriosis of the sacral splanchnic nerves

This code represents the presence of endometrial tissue abnormally located on or infiltrating the sacral splanchnic nerves. This condition can cause chronic pelvic pain, dyspareunia, and bowel or bladder dysfunction due to nerve compression or irritation. It is a specific manifestation of deep infiltrating endometriosis affecting the nervous system.

Use this code when documentation explicitly states endometriosis involving the sacral splanchnic nerves. This diagnosis is typically confirmed through advanced imaging (e.g., MRI) or surgical exploration with biopsy. It is appropriate for patients presenting with neurological symptoms referable to the sacral plexus in the context of known or suspected endometriosis.

• Ensure documentation clearly specifies "sacral splanchnic nerves" and not just general pelvic nerve involvement.
• Do not confuse with endometriosis of other pelvic nerves (e.g., sciatic nerve) which have different codes.
• Sequence this code after the primary diagnosis of endometriosis (N80.0-N80.9) if it is a manifestation or complication.
