Endometriosis of the sacral nerve roots

This code represents the presence of endometrial tissue abnormally located on or infiltrating the sacral nerve roots. This condition can cause significant neuropathic pain, radiculopathy, and other neurological symptoms in the pelvic and lower extremity regions, often exacerbated during menstruation.

Use this code when documentation explicitly states endometriosis affecting the sacral nerve roots, typically confirmed by imaging (e.g., MRI) or surgical findings. This diagnosis is often made in patients presenting with chronic pelvic pain, sciatica-like symptoms, or bowel/bladder dysfunction linked to their menstrual cycle.

• Ensure the documentation clearly specifies "sacral nerve roots" and not just general pelvic endometriosis.
• Code any associated pain or neurological symptoms separately, if documented, as secondary diagnoses.
• Distinguish from endometriosis affecting other pelvic nerves or structures, which would be coded differently.
