The American Medical Association sent a letter to Senate leaders, outlining the society's opposition to the Better Care Reconciliation Act.
Here are four things to know:
1. The AMA has consistently warned reforms should not impact individuals' insurance access, affordability or quality. The association argues the Senate's proposed bill goes against those values.
2. Senate Republicans unveiled their draft legislation to repeal and replace the ACA on June 22.
3. The Senate created the BCRA in response to the House's version called the American Health Care Act.
"On behalf of the physician and medical student members of the American Medical Association, I am writing to express our opposition to the discussion draft of the 'Better Care Reconciliation Act' released on June 22, 2017," the letter begins. "Medicine has long operated under the precept of Primum non nocere, or 'first, do no harm.' The draft legislation violates that standard on many levels."
