Currently in a group HMO plan. Living in Pa.
When I stopped working my employer considered me to be retired and that allowed me to purchase my health insurance from them. I used COBRA initially and then went into the retiree health plan. When Medicare kicks in I will be able to continue with a supplemental plan through my employer. It is not cheap but it is quality coverage and it is easy. So the short answer is check with your employers first to see what might be available.
