Boy supplemental you mean a second medical provider?
The supplemental pays the Medicare copay.
Most people should take a serious look at their assets and consider a trust to avoid the 5 year Medicaid lookback that takes their pension, social security, bank and pension accounts, and their home.
If you have no spouse or children, you are screwed.
Our supplemental plan to Medicare would not pay out for anything that Medicare denied. We got far less in reimbursements from them than the premium we were paying. We switched over toa good Medicare Advantage plan for our area.
For prescriptions, we used Good Rx and Good Rx Gold and they were better than what Medicare had to offer.
Some drug companies has financial assistance programs for people who meet the qualifications based on income. Those are often worth checking out.
We’re getting assistance from two that has helped my prescription costs immensely.
