A doctor raised more than $250 million to create a new kind of clinic that charges a monthly fee, and it could be the future of medicine

In the future, going to the doctor's office might start to feel different, with you or your insurer paying a monthly fee for routine access to your doctor without paying a copay. It's the model for Iora Health, a startup that works with "sponsors" — mainly employers or private health plans for the elderly (known as Medicare Advantage) — that cover the monthly fee. Iora also built out care teams of nurses and other health professionals that can help the doctors within the practice.
