American bishops said Thursday that the Obama administration's latest compromise on birth control coverage and religious employers doesn't go far enough to answer church concerns.The U.S. Conference of Catholic Bishops said more of a buffer is needed between religious charities and any third party arranging contraceptive coverage. Bishops also want a clearer statement that faith-affiliated hospitals and other nonprofits are religious ministries.And church leaders continue pressing for an exemption for owners of for-profit business who say the requirement forces them to violate their religious beliefs. The government has given no indication that it is considering a religious opt-out for business owners.The bishops made their comments nearly a week after the Department of Health and Human Services announced another revision on coverage for contraception. The regulation is part of President Barack Obama's healthcare overhaul, known as the Affordable Care Act, and is meant to help space pregnancies and promote women's health.The department had no reaction to the bishops' criticism, pointing only to an earlier pledge that the government wants to find a solution that would provide coverage to women while respecting religious concerns.The HHS announced the proposed rules a year ago. The initial plan contained a religious exemption that many faith groups, including many who have been supportive of healthcare reform, said was too narrow. The rule covered churches and other houses of worship but not faith-affiliated hospitals, charities, colleges and other nonprofits.Dozens of religious groups and for-profit business owners have sued over the regulation, saying it violates their religious rights. Advocates for the broadest coverage argued that employers are trying to impose their religious beliefs on workers.The Obama administration, meanwhile, has been trying to develop a plan that could resolve religious concerns.Under the proposal the government offered last week, the definition of a religious organization was simplified.For other religious employers, the new approach attempted to put a barrier between religious charities and contraception coverage. Female employees would still have free access through insurers or a third party, but the employer would not have to arrange for the coverage or pay for it. Insurers would be reimbursed for any costs by a credit against fees owed the government.
