Did you think Medicare was free - only part of it is premium free - Part A - you & your employer paid for Part A during your work years by payroll taxes.
Part B has a premium - for most people the 2022 premium is $ 170.10 per month. That can be higher based on your (higher than) income or lower to none at all also based on (low) income.

You need to make sure that the employer plan that you currently have is considered creditable for your prescriptions drug coverage by Medicare cause if not you need to sign up for a Medicare Prescription Drug plan too OR pay a late sign-up premium penalty when you do sign up.
If it is creditable, that's good but as soon as you no longer have it - sign up for one.
Might be a good time to just get the basics down - a good starting point is the link below - cause there will be other decisions that you and wife will have to make when the employer coverage ends, like how you each want to get your Medicare coverage (original or Med. Advantage) and if Original is your choice, do you want a Medicare Supplemental plan (Medigap) to pick up some of your out of pocket cost.
