My insurance refused to pay for a hysterectomy for adenomyosis untill everything else had been ruled out. The problem with Adenomyosis is that it can't be 100% proven untill the uterus is removed and tested. So basically I had to jump through alot of hoops before insurance would pay.
Have you had other things ruled out? I ask because after all my years of pain and bleeding, once I had my hysterectomy and the testing was done, I found out I did not have Adenomyosis after all. No way to know what caused all my issues.
