Before the Maryland attorney general said that the state would immediately begin recognizing out-of-state gay marriages, insurance companies doing business in Maryland already had to give coverage to domestic partners of employees in the state if their employers requested it.

The insurance administration will likely add that insurance companies must provide insurance to same-sex spouses, just as it already requires providing to same-sex domestic partners.
