Kansan Kathleen Sebelius, the US Department of Health and Human Services Secretary announced that the Health Plan Finder tool on www.healthcare.gov now allows for users to search for insurance plans that include coverage for domestic partners.
On this site, consumers can compare health plans and employers of a small business can also search for employee coverage. The website breaks it into categories to help you choose the best option based on enrollment, out-of-pocket expenses, and specific benefits.
Some states have passed same-sex marriage laws and insurance companies are just a few steps behind.
Hope this helps.
