@jessicaalbrecht I'm so sorry to hear what your husband is going through. I eventually found this page here that might help - it has information on elemental formula coverage laws in a lot of states and a link to a guide on how to talk to an insurance company about it: https://www.foodallergyawareness.org/living-with-food-allergies/statewide-insurance-coverage-for-elemental-formula/. At this point I still have not found a formula that will be safe for me, so I may not end up going that route, but I did get a diagnosis - I have Crohn's colitis. It's a type of Crohn's that behaves a bit like ulcerative colitis in the sense that it affects only my colon, and in my case it's located on the right side, where the blockage sensation was. I am on Budesonide and Entyvio for it now. The Budesonide got rid of the blockage feeling within a day or two, and my motility is improving now that I've started the Entyvio.
