Republican U.S. Rep. Elise Stefanik on Friday morning announced she had and a coalition of lawmakers had negotiated $15 billion in benefits care such as maternity, mental health and substance abuse treatment for the House GOP-backed health care bill.

In a statement Friday morning, Stefanik said the money would come from the Patient and State Stability Fund, with supplemental funding in order to receive additional resources for new mothers, those struggling with addiction or mental health problems.

The measure is described as helping provide funding while the “nation transitions” to the new health law, should it pass.

House Speaker Paul Ryan in a statement said he agreed to the amendment.

The inclusion of the amendment is potentially key as the House GOP’s leadership seeks to stitch together enough votes for passage of the bill, known as the American Health Care Act, on Friday.

Stefanik, a North Country lawmaker and the co-chair of the moderate Tuesday Group, is a potentially pivotal vote for the legislation.

“Throughout negotiations with Congressional leadership and the White House, I have insisted that protections for maternity care must be included in any final package,” Stefanik said. “I spoke out in support of protections for mothers and children in meetings at the White House and with the House Leadership and Committee Chairs who have drafted this replacement legislation. I am pleased that I was able to secure this critical amendment.”

Stefanik’s planned vote had not been clear on the bill, and Republicans canceled a planned vote Thursday on the legislation, rescheduling it to today.

It’s not yet clear if House Republicans have enough votes for the passage of the bill. Two New York congressmen — Reps. John Faso and Chris Collins — have tried to bring around upstate members with a provision that would require state government pick up the county share of the Medicaid program.

Gov. Andrew Cuomo and his administration have railed against the Faso-Collins amendment and its potential impact on the state’s finances. The measure wouldn’t take effect until 2020.
