Anyone on public health insurance would not be able to visit a Planned Parenthood, period,” a Planned Parenthood executive in Massachusetts said.

The federal government and many states already block using Medicaid funds to cover abortion. But the state-federal health insurance program for lower-income people does pay for other services from Planned Parenthood, including birth control, cancer screenings and testing and treatment for sexually transmitted infections.

The Supreme Court upheld South Carolina's bid to defund Planned Parenthood, ruling that Medicaid patients cannot sue to choose their provider. The court held in a 6-3 ruling along ideological lines, with the conservative justices in the majority.
