In simple words: Adenomyosis is a condition where the tissue that normally lines the inside of the uterus grows into the uterine muscle. This can cause heavy bleeding, pain during periods, and pelvic pain.Treatment options depend on the severity of symptoms and may include medication or surgery.

Adenomyosis of the uterus, also known as adenomyosis, is a benign condition characterized by the presence of endometrial glands and stroma within the myometrium (the muscular layer of the uterine wall).This ectopic endometrial tissue can cause abnormal uterine bleeding, pelvic pain, and dysmenorrhea (painful menstruation). The exact etiology is unknown, but theories include retrograde menstruation, metaplasia, and vascular dissemination.Diagnosis is typically made through clinical presentation, imaging (transvaginal ultrasound, MRI), and potentially laparoscopy or hysterectomy. Treatment options range from conservative management (pain control, hormonal therapy) to surgical intervention (hysterectomy, uterine artery embolization).

Example 1: A 35-year-old woman presents with heavy menstrual bleeding (menorrhagia) and severe pelvic pain during menstruation (dysmenorrhea).Transvaginal ultrasound reveals diffuse thickening of the uterine myometrium, suggestive of adenomyosis.The patient is initially treated with hormonal therapy (GnRH agonist) to control her symptoms., A 42-year-old woman with a history of infertility and chronic pelvic pain undergoes laparoscopy, which reveals adenomyosis.Given her age and desire for no further pregnancies, she opts for a total hysterectomy to alleviate her symptoms permanently. , A 48-year-old perimenopausal woman experiencing menorrhagia and pelvic pressure undergoes MRI which confirms adenomyosis. Due to age and menopausal symptoms management options focus on controlling bleeding and pain with hormonal therapy until menopause naturally ensues.

** Adenomyosis can coexist with other uterine conditions, such as fibroids or endometriosis. Accurate coding requires careful review of all available clinical documentation to ensure appropriate coding and reimbursement.
