Superficial endometriosis of the uterus

This code signifies the presence of endometrial tissue growing on the outer surface of the uterus, rather than within the uterine lining. This superficial ectopic endometrial growth can cause pelvic pain, dysmenorrhea, and infertility. It represents a specific anatomical location of endometriosis.

Apply this code when documentation explicitly states "superficial endometriosis of the uterus" or "endometriosis on the serosa of the uterus." This diagnosis is typically confirmed via laparoscopic visualization and/or biopsy. Use for patients presenting with symptoms attributable to this specific location of endometriosis.

• Differentiate from adenomyosis (endometriosis within the myometrium) and endometriosis of other pelvic sites.
• Ensure documentation specifies "superficial" and "uterus" to avoid coding to a less specific or incorrect site.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
