Use the most specific code available. If the side of the lesion is documented, use N80.3A1 or N80.3A2. If both sides are affected, use N80.3A3. If the depth is known to be deep, use N80.3B9.

In simple words: This code indicates the presence of superficial endometriosis (endometrial tissue growth outside the uterus) on the uterosacral ligaments (ligaments that connect the uterus to the sacrum), without specifying the affected side.

Superficial endometriosis of the uterosacral ligament(s), unspecified side.This code specifies the presence of endometriosis on the surface of the uterosacral ligaments, without specifying whether it affects the right, left, or both ligaments.

Example 1: A 30-year-old female presents with chronic pelvic pain.Laparoscopic examination reveals superficial endometriosis on the uterosacral ligaments, without clear lateralization.N80.3A9 is used., A patient undergoes a hysterectomy for uterine fibroids. During the procedure, the surgeon incidentally notes superficial endometriosis on one of the uterosacral ligaments, but does not specify which one.N80.3A9 is appropriate., A patient with infertility undergoes pelvic imaging. The radiologist reports superficial endometriosis involving a uterosacral ligament, but the side is indeterminate on the images. N80.3A9 is assigned.

Documentation should include the location and depth of endometriosis, ideally with laterality specified. Supporting clinical findings, such as pelvic pain or infertility, should also be noted.
