Big Insurance [HMO subset] takes a hit. The U.S. Supreme Court has said that a 1974 federal law does not apply to Kentucky's HMO statute, and that any doctor that agrees to the terms of the HMO contract must be accepted as an HMO doc, per the state law.

Makes sense to me. While the HMOs say that there will be cost and quality implications affecting the level of care they can provide if they can't be selective, I don't see how, if the docs are agreeing to the HMO contract.
