UPDATE
The new governor of AZ, Jane Hull overruled this legislation when she took office.
A health insurance plan is designed based on what the employer wants. So if a plan says that domestic partners are covered then the employer group is the one that put that wording in the policy. So if an employer wont cover a domestic partner then domestic partners aren't covered company wide.
King's Health Partners was created in 2009.
Continuum Health Partners was created in 1997.
Probably not. New York City, for example, still maintains its domestic partnership registry. Most large employers have not eliminated their domestic partner benefits and insurance companies continue to sell domestic partner coverage.
Yes, they do give their employees domestic partner benefits, according to the Human Rights Campaign Foundation's Corporate Equality Index 2013, which gave Target a 100% rating.
Yes, an employer can offer coverage to same-sex domestic partners and/or deny coverage for opposite sex domestic partners. You should ask your HR/Benefits representative for a copy of your plans eligibility rules, which will show who you may enroll and more importantly, when you can enroll them.
Yes, if one of the domestic partners works for the state or for an employee who has voluntarily opted to provide domestic partner coverage. Keep in mind that no new domestic partnerships may be formed in New Jersey after February 19, 2007, since Civil Unions are now legal.
Missouri does not recognize "common law" marriages or domestic partners. Health insurers are not required to offer joint plans for unmarried people. You would have to buy two separate plans -- one for each of you.
An employee must pay federal tax on the cost of the premiums for insurance provided by the employer for the employee's domestic partner.
Your employers' plans may allow you to cover "domestic partners". To qualify as a domestic partner, you will have to show some proof -- such as a joint lease or joint checking account. Some plans' standards are quite high, so be prepared to shower them with proof. Assuming that you qualify, then one of you can join the other's health plan before the wedding.
Generally the prevailing law is the state that the plan originates in. Example: A client of mine covered his domestic partner under his health plan. The company was sold to a competitor out of state. The state where the new company resided did not recosnize domestic partners. Even though the state he lived and worked in did, his partner lost coverage.
You can look on the health partners site or you could try contacting their main hub. This would be your two best options for finding out if there are available positions.
