Cuts to Medicaid proposed by Republicans in the U.S. House and Senate jeopardize addiction treatment, NPR reports.

In Pennsylvania, more than 124,000 residents depend on Medicaid for addiction treatment. The state’s Medicaid program currently pays for addiction treatment with Vivitrol, a monthly injection that costs about $1,000 a dose. A person receiving the shots also has weekly therapy sessions and visits with a recovery coach, also paid for by Medicaid. Pennsylvania, which expanded Medicaid under the Affordable Care Act, pays no more than 10 percent of costs for patients who gained coverage under the expansion. The federal government funds the rest.

The Republican health care bill that passed the House and is being considered by the Senate would cut Medicaid spending by more than $800 billion across 10 years nationwide, the article notes. If the federal government cuts Medicaid funding, states either would have to come up with the rest of the money, limit access to care, or cut off coverage for some people.
