In simple words: This code describes a condition where tissue similar to the lining of the uterus grows outside of the uterus, specifically on the left side of a ligament supporting the uterus. The doctor needs more information to determine how deep the tissue is growing.

This code signifies the presence of endometriosis specifically located on the left uterosacral ligament.The depth of the endometriosis is not specified, requiring further clinical investigation to determine the extent of the disease.

Example 1: A 35-year-old female presents with chronic pelvic pain and irregular menstrual bleeding.Laparoscopic examination reveals endometriosis on the left uterosacral ligament, depth unspecified.This would be coded as N80.3C2., A 40-year-old patient undergoing a hysterectomy for unrelated reasons has incidental findings of endometriosis on the left uterosacral ligament during the procedure. The depth is not further characterized. N80.3C2 is used., A 28-year-old woman with infertility undergoes an investigation that reveals endometriosis on her left uterosacral ligament; further investigation into the depth is not possible during the initial procedure. N80.3C2 applies.

Complete clinical history, including symptoms, physical examination findings, imaging reports (e.g., ultrasound, MRI), and operative report if applicable.If surgery was performed, the report should detail the location and extent of the endometriosis, ideally stating the depth if possible.

** The unspecified depth (in this case) may necessitate further investigation to appropriately guide treatment strategy and prognosis.
