@billb720301 I’m not sure how other insurance companies work but Blue Cross provide me a case advocate who connected me to one of their registered dieticians. I developed, what they thought, was IBS after getting c-diff following bowel obstruction surgery. The dietician was familiar with the FODMAP diet I was told to follow as well as with other dietary suggestions. Ended up I do not have IBS but a year later, I still try to eat similar to what I was. No raw veggies so no salads, baked or grilled meats, lactose free Greek yogurt, potatoes sliced and baked with a little olive oil, salt and pepper, and squash and asparagus broiled in the over. No broccoli or corn though.
Good luck!
