Sharpening an election-year confrontation over religious freedom and government health insurance rules, the nation's Catholic hospitals on Friday rejected President Barack Obama's compromise for providing birth control coverage to their women employees.

The Catholic Health Association was a key ally in Obama's health care overhaul, defying opposition from church bishops to help the president win approval in Congress. But the group said Friday it does not believe church-affiliated employers should have to provide birth control as a free preventive service, as the law now requires.

The hospital group's decision calls into question a compromise offered by the president himself only months ago, under which the cost of providing birth control would be covered by insurance companies and not religious employers. While churches and other places of worship are exempt from the birth control mandate, nonprofits affiliated with a religion, such as hospitals, are not.

In a letter to the federal Health and Human Services department, the hospital group said the compromise initially seemed to be "a good first step" but that examination of the details proved disappointing. The plan would be "unduly cumbersome" to carry out and "unlikely to adequately meet the religious liberty concerns" of all its members, the group said.

While some liberal-leaning religious groups see no problem with the birth control rule, Roman Catholic bishops and conservative-leaning groups are treating it as an affront and calling it an attack on religious freedom. Institutions ranging from the University of Notre Dame to Catholic Charities in several states to the Archdiocese of Washington have sued to block the rule.

With the Catholic Health Association now voicing concerns, opponents gained a powerful endorsement. There was no immediate reaction from the Obama administration.

The association represents about 600 hospitals and hundreds of nursing homes and other health-related organizations, totaling 2,000 members around the country. One of every six patients is cared for in a Catholic hospital.

In its letter, the group said the government should either broaden the exemption for religious employers, or pay directly for the birth control coverage.

Starting next Jan, 1, in most cases, women will have access to birth control at no additional charge through their job-based coverage, as part of a package of preventive services that also includes HIV screening and support for breast-feeding mothers. Some employers, considered to be "grandfathered" in under the health care law, will not have to provide the coverage. Continued...
