You do not code symptoms of a diagnosis. However, you need to know if the dysmenorrhea is a symptom of the uterine fibroids or not:
Dysmenorrhea
Dysmenorrhea, also known as menstrual cramps, is a condition that includes pain right before and during menstruation that can range from mild to severe. The types of pain that are associated with dysmenorrhea include sharp, burning, throbbing, dull, burning, or shooting in the hips, lower back, or inner thighs. Other symptoms that can accompany dysmenorrhea include vomiting or diarrhea.
The term primary dysmenorrhea is used to describe menstrual cramps that occur without an identifiable cause other than menstruation, while secondary dysmenorrhea is caused by something other than menstruation. Secondary dysmenorrhea can be caused by endometriosis, ovarian cysts, fibroids, cervical or uterine polyps, pelvic infections, or structural problems in a woman’s uterus, cervix, or vagina.

Either you need to see if clarification is in the rest OP report, or query the doc
OR it is a possible a more experienced coder (I'm still new) would know if the doc would list secondary dysmenorrhea in this fashion.
