I had United Healthcare with my last employer before retirement. They were really good and covered to major surgeries and the physical therapy with no out of pocket expenses. I decided use them as the supplement for my medicare. the F plan. The premium for the F plan supplement was 99.00 per month. Since retirement I have had I two stent surgeries and one colon surgery. My out of pocket expense has been $0.00. In the 4 years of medicare my supplement is now 300.00 a month. Mom and Dad's supplement with BCBS in KS is over $400.00 a month. Coverage's are good if you can afford it.
