If you have ever belonged to a labor union, Ask them.
Else you can ask any agent that sells health insurance
And you can still contact prospective insurance companies either via E-mail or phone and request information..
The only "unique" thing about healthcare.gov is that there is little if any bias there.. Most agents suffer from bias. Thy recommend the company that pays them or pays them best... The government web site does not.
That said. I do belong to a union and the plan I have needs not be replaced.
Oh, talk to your current insurer, they may have a plan that qualifies that is reasonable and may be able to give you a loyality discount.. KEY WORD MAY.
