Just because it is a PPO doesn't mean that the provider has to accept the coverage. The provider still has to agree to the plans terms and conditions. I have seen many places where they refuse UHC whether it's HMO or PPO. UHC is having network issues in NC with UNC and in SC with Prisma Health. Just moved a client today from UHC to Humana due to the UNC negotiations not looking promising.As long as PPO's are available, it's really not a huge deal. If it was just HMO's like pre-2016, then yes...major deal. The difference in copays on most Medicare Advantage PPO's between "in-network" and "out-of-network" is not some monumental difference. People are already getting most of these plans at $0/month. If they have to pay a little bit more for a few copays, it's not the end of the world. It would obviously be preferable if they didn't have to, but the benefits of the plans are still great.
