Planned Parenthood and two smaller regional abortion providers are resuming billing Medicaid for services other than abortion after being cut off for most of a year.

The defunding, which was mandated in President Donald Trump’s big tax and policy law last year, has been blamed in the closure of multiple clinics as well as a reduction in the number of Planned Parenthood patients being screened for breast cancer or tested for sexually transmitted infections.

The Medicaid billing was allowed to resume Sunday.

The restored funding does not mean the battle over federal abortion policy has ended, and not all services that were cut will return.

Here’s what to know about the situation.
