State by state

Texas is among 10 states with similar admitting-privileges requirements, according to the Center for Reproductive Rights. The requirement is in effect in most of Texas, Missouri, North Dakota and Tennessee. It is on hold in Alabama, Kansas, Louisiana, Mississippi, Oklahoma and Wisconsin.

The hospital-like outpatient surgery standards are in place in Michigan, Missouri, Pennsylvania and Virginia, and they are blocked in Tennessee and Texas.

Separate lawsuits are pending over admitting-privileges laws in Louisiana and Mississippi, the other states covered by the Fifth Circuit. The laws are on hold in both states, and a panel of federal appellate judges has concluded the Mississippi law probably is unconstitutional because it would force the only abortion clinic in the state to close.

A separate appeal is pending at the Supreme Court from Wisconsin, where federal judges have struck down that state's admitting-privileges law.
