State preemption only in event of conflict

The provisions of sections 302 through 305 (including the amendments made by such sections) shall not supersede any provision of State law which establishes, implements, or continues in effect any requirement or prohibition related to health care price transparency, including hospital, clinical diagnostic laboratory tests, imaging services, and ambulatory surgical center, except to the extent that such requirement or prohibition prevents the application of a requirement or prohibition of such sections (or amendment). Nothing in this section shall be construed to affect group health plans established under the Employee Retirement Income Security Act of 1974, or alter the application of section 514 of such Act (29 U.S.C. 1144).
