I am not a Doctor, so I can only assume that they might not like Medicare Advantage plans too much because they may not get paid as much for certain services. Medicare Advantage plans are considered managed care plans, so many time the Dr and patient have to get prior authorizations for certain procedures, this could delay the patients care and take administrators time and energy.
Doctors dislike Medicare Advantage plans due to administrative burdens, low reimbursement rates, and frequent denials of care, which impact their practice and patient care.
Doctors have three main reasons for disliking MA plans: A) they don't want to do the paperwork involved with these types of (free of premiums, govt-subsidized) plans, B) due to that paperwork, they would be forced to hire more people to administer the plans, and
C) Advantage plans take much longer to pay the in and out of network physicians and thus want nothing to do with any Advantage plan. But they gladly take on patients with Medicare Supplements, a.k.a., Medigap plans.
Medicare Advantage plans are managed care plans. This means that the insurance companies have the ability to require different things to receive care like preauthorizations, step therapies, and limitations on certain types of procedures.
Because the Advantage plans are MCO Managed Care Organizations who are trying to add profit to their bottom line. They pay less to the Dr and have more restrictions on what they will cover for you. When the rubber meets the road your "grocery card" benefits matter if your Dr is not in network .
It isn't that they don't like them per se...it is because they have a higher oversight. Things need to be approved by the carrier. They like to just run the tests for payment on original medicare. They do not want to have a insurance plan tell them no. Now, this could be a good thing and maybe a frustrating thing. But medicare abuse is a real thing.
Because everything has to go through a pre-authorizion process, the doctors feel like the insurance carriers have to much control over patients health care. Medicare Supplements typically do not need referrals.
