For anyone on Medicare pay attention to your chosen plan. There are some changes being slipped in that some may not notice if they are not paying attention. The changes involve "deductibles" the insured has to pay before the insurance pays anything.
These deductibles apply to any health related visit to a doctor or prescriptions. They do vary by plan but can be costly for those on tight budgets
I hoping this will stay non political as it is meant to be an informative post

I'll add. whatever you got, enjoy it while you have it.

I weighed my options and only took part A for now , still on company insurance for foreseeable future ,zero cost and 2500 deduct

Wifey and I are on part A, B, and D Medicare with supplements. The no cost, provide everything "plans" smack too much of HMO's and I've old enough to remember what a fiasco they were.

I have Medicare A & B, $240 deductible.
Best thing is my supplemental Plan G through Mutual of Omaha - $163.35/mo.
Eye surgeries & hip replacement cost me next to nothing, yearly deductible is something like $300 (don't recall exactly at this moment, but it's low).
I pay for meds because I don't take many and it's kind of a wash, coverage cost vs out-of-pocket.

SO much better than when I had Obamacare some years ago and my kidney surgery cost me $20,000.

friday my wife and i are meeting with our insurance lady to go over what is out there for next year that will meet our needs.
what concerns me the most, is the possibility of "pre-existing conditions" being a cost escalator that will be unaffordable for us [and others] to obtain the health care we need.
this greatly concerns me, and i'll leave it at that.

Wow!! I didn't know you had kidney surgery! My wife is on the transplant list at the University of Iowa Hospitals and Clinics. She got a call two days ago and is on standby meaning that her bags are packed are ready to go!

Oh yeah, Ted - left one was almost completely blocked - they called it a "staghorn" - several hours' surgery.
Three follow-ups after that for the ultrasound deal.
It was all a pretty big deal.

Sounds like you are doing well!

Yes, the advantage plans can suck with all the co pays and deductibles

And some Doctors have stopped taking some of the plans , but regular medicare not a problem

So A, and B with the gap covered by G and then a D for Rx drugs , not the easiest to figure out

But at least I'm not paying the $40 on everything co pay I did under the affordable care act

So far all I have had to pay is the typical $20 copay. Got lots done in the last year I couldn't afford to do before Medicare!

that didn't take long

You expect less I guess?

Been on Medicare plus the supplement for 10 years. Type F, never have paid a dime, no copays. My agent told me five years ago the advantage plan is no good if you're sick a lot, I’ll stick with what I have, I like walking in and out, last hospital bill was $300,000 in may, 0 for me. Now other shoulder then knee in future.

if you're both on Medicare, pre -existing conditions shouldn't come into play. The same for Obamacare.
Keep us posted on your findings

If I may ask, what does A, B, G and D total a month or year on premiums ?
And what other expenses may total? Dental, optical copays on prescriptions, earing aids etc.

I ask as up to now we have paid ZERO for insurance (175 a month standard fee) and the other expenses have been ) or minimal.
But it does depends on the plan

Previously we were paying ~ 200 a month in additional premiums or 2400 a year

Switching to an ADV plan that had a 4K max out of packet expense we had that covered in 20 months and have saved another 4500 or so since. Again it depends on the plan on selects.

I was on Obamacare in 2017 when I had a triple bypass that went sideways. I was in an induced coma for ~ 3 weeks, transferred to specialty facility for ~1.5 weeks. That was followed by 4 weeks of inpatient therapy. Total cost was under 3-4K. The first bill arrived 4 days after the procedure it was over 400K .

Plan F is no longer available unless you're grandfathered in. It was replaced with G

one of the main concerns, is finding a drug plan that covers the drugs we need, [formulary] while being able to afford the plan and any co-pays the drugs will cost us. several drugs we take are hugely expensive.
as we are both on medicare, that part doesn't bother us.
