@Andora, is name-calling ever appropriate? This is not PI. Plus you said: "I'm sorry, but I can't find it in myself to see this as tragic." Why not? A human person lost his life & his family & friends are deeply affected. If a family member of yours was gunned down because of his/her business practices would that be okay with you?
When I first went to work for the employer that I retired from the ins company (I think Aetna) who handled our insurance claims denied a good many of my legitimate claims. It was so annoying. I had to appeal & then they finally always paid. Depending on the amount some employees wouldn't bother calling, sitting on hold, etc to appeal so Aetna made illegal profit. My company changed to UHC after many complaints & it was so much better that maybe I think they are good just in comparison.
It may also have been the plan from Aneta and UHC your employer purchased. I know you've said that your employer was/still is self funded but
they still purchase the insurer plans with specific criteria.
I believe my dad retired from the same company as you. I'm fairly certain it was administered by UHC. His experience was different than yours, he also lived in another state.
My experience comes from years of doing authorization for care. - I dealt with UHC, Aneta, Medica, Cigna, BC/BS etc. Thank Goodness I left that job 15 years ago. It was a nightmare then.
Plans and coverage were different across the board. UHC for company A was not the same as UHC for company B.
BC/BS for company A plans were different than Company B plans.
I dealt with mostly Medicaid or CHIP pools patient coverages. UHC was by far the cheapest and gave some perks like taxi rides to Dr offices but not much coverage for PT, OT and very little is any for Speech therapy. My state offered UHC or BCBS. UHC Medicaid plans were the worst for coverage in Nebraska. UHC would not cover respite care from lowa to Nebraska, even though there were not options available in Iowa. I did deal with other company insurers.
Medicare is a freaking nightmare. All HC companies have to offer the plans - I'm in supplemental plan G. Every company that offers Media-Gap plans, must offer about 6 or 7 plan category. All of which are mandated to offer the exact same plans features. Each company can set premium costs, with different co-pays, different deductible. But the same features.
As far as I know, there are no mandates on coverages for non Medicare plans.
I have no idea what the companies who sell Medicare Advantage plans are mandated to cover. Because I know too many people where plans drop providers and you are searching for new providers who accept the meager reimbursement rates.
