It sounds like you will be responsible for all of the health insurance premiums in retirement, whereas your employer used to pay a big chunk of them. Is that correct?
Health insurance premiums are all over the place, but 10K/year doesn't sound crazy to me. We are covered by the (non HSA) federal plan for Employee + Spouse, and total premiums run about 20K/year. We pay ~1/3 of it, Feds pay the rest of that cost. So if we had to pick up the total cost it would be ~10K/year/person.
