As a physician, I’ve had to speak to these so called “peers” in a peer to peer denials with both my clinic and hospital setting. They are usually people who aren’t physicians as a first line of their defense, ie therapist, nurses, etc. This weeds out the providers who either don’t care about the patient denial and blindly accept the denial, or patient has to take matters in their own hands just to get the care they need/deserve. Or worse, in the hospital that means the patient gets hit with a huge bill (already an insane number in the US even with insurance, so don’t get me started on this) or it gets delegated to another provider who has to deal with it. Quite often patients get denied medical and rehab services, esp after something debilitating like a stroke, trauma/accident, etc. and at that point the peer to peer is to weed the provider out. Usually someone will tell the patient you’ve been denied, either go home without the services they need or you fight it.

I fight it. Can’t count the number of times I’ve spoken to someone not in the field of medicine or if they are, not my field of medicine (both Family/Hospital Medicine). Often I’m fighting with an MD or “practitioner” who is some other field like a gynecologist about hospital medicine services or rehab. I’ve even had the pleasure of talking to a physical therapist and didn’t let me get a word in as we began the peer to peer. I now start of by asking for their credentials and field of speciality and demand a peer of my field to do the denying if they are so adamant about it “not being medically necessary”.

I have so much to say and could write a book about it. I just wish I had the money and connections to actually change the state of US of Corporate Medicine.

Traditional Medicare consists of Part A (hospitals), Part B (doctors) and Part D (drugs). Part A+B don't cover everything so you have a Medigap plan. I have Plan G which has very little paperwork. All up, I spend about $400/mo and I'm very happy with A+B+G+D.

With Medicare Advantage you sign over your Medicare rights+benefits to a private insurer. This may save you some money, especially early on. In fairness, not really a lot and the $0/mo plans are a scam. With Medicare Advantage, you will then have to argue with an insurance company for the rest of your life. You'll have to deal with preauthorizations and a restricted network.

With Traditional Medicare, what's covered is spelled out pretty clearly ahead of time. Docs know it. You know it. There's literally an app for that. With Medicare Advantage, medically necessary is at the discretion of the private insurance company.

Here is the scenario from a relative: he had a heart event which ended up needing a stent. He had to argue with Kaiser while this was going on. Kaiser is 240,000 people. He is one.

Medicare Advantage is very profitable.

It is possible to switch back from MA to TM which really revolves around your Medigap plan. You are guaranteed issue for Medigap plans for about 3 months before/after you turn 65. After that, you will have to undergo medical underwriting.
