Senate Republicans are again trying to ram through an Affordable Care Act replacement that threatens the health and well-being of millions of Americans. It’s shameful. But don’t take my word for it. Let’s look at what people who actually work in health care are saying about the Graham-Cassidy-Heller-Johnson bill.

In this interview, Sen. Bill Cassidy insists that his bill would protect people with pre-existing conditions. Blue Cross Blue Shield Association disagrees. (Cassidy also says in that same interview that his bill would work through the Children’s Health Insurance Program (CHIP), which he said has been reauthorized. That’s totally false — CHIP has not been reauthorized and its funding expires Sept. 30.) But back to pre-existing conditions — here’s what Blue Cross Blue Shield had to say:

Although we support providing states with greater flexibility in shaping health care options for their residents, we share the significant concerns of many health care organizations about the proposed Graham-Cassidy bill. The bill contains provisions that would allow states to waive key consumer protections, as well as undermine safeguards for those with pre-existing medical conditions. The legislation reduces funding for many states significantly and would increase uncertainty in the marketplace, making coverage more expensive and jeopardizing Americans’ choice of health plans.

America’s Health Insurance Plans just released this letter that was sent to Senate leaders Mitch McConnell, R-KY, and Charles Schumer, D-NY. Guess what? They also read the proposed repeal as taking away protections for pre-exiting conditions:

The Graham-Cassidy-Heller-Johnson proposal…would have real consequences on consumers and patients by further destabilizing the individual market; cutting Medicaid; pulling back on protections for pre-existing conditions; not ending taxes on health insurance premiums and benefits; and potentially allowing government-controlled, single-payer health care to grow.

AARP thinks so too:

Overall, the Graham/Cassidy/Heller/Johnson bill would increase health care costs for older Americans with an age tax, decrease coverage, and undermine preexisting condition protections. In addition, this bill would jeopardize the ability of older Americans and people with disabilities to stay in their own homes as they age and threaten coverage for individuals in nursing homes.

Cassidy insists more people will have coverage under his plan. But strangely, people that actually deliver medical care to people disagree. Here’s what the Children’s Hospital Association had to say:

Their legislation would slash funding for Medicaid, the nation’s largest health care program for children, by one-third, reducing access and coverage for more than 30 million children in the program. Furthermore, the legislation weakens important consumer safeguards, and as a result, millions of children in working families would no longer be assured that their private insurance covers the most basic of services without annual and lifetime limits and regardless of any underlying medical condition. This bill would have devastating consequences for children and families.

In a letter to Senate leaders, the American Medical Association writes:

Similar to proposals that were considered in the Senate in July, we believe the Graham-Cassidy Amendment would result in millions of Americans losing their health insurance coverage, destabilize health insurance markets, and decrease access to affordable coverage and care. We are particularly concerned with provisions that repeal the ACA’s premium tax credits, cost-sharing reductions, small business tax credit, and Medicaid expansion, and that provide inadequate and temporary block grant funds (only through 2026) in lieu of the ACA’s spending on marketplace subsidies and the Medicaid expansion.

Not surprisingly, the Republican replacement is bad for women’s health too. According to Planned Parenthood:

The Graham-Cassidy-Heller proposal includes a provision that would block millions of people from going to Planned Parenthood for preventive care, including birth control, cancer screenings, and STD testing and treatment.

And because Cassidy’s bill would allow states to weaken pre-existing condition coverage and the requirement that insurers cover a set of essential health benefits, coverage of maternity care would be at serious risk. According to an analysis from the Center on Budget and Policy Priorities:

While insurers would still be required to offer coverage to people with pre-existing conditions, insurers could charge unaffordable premiums of thousands or tens of thousands of dollars per month, effectively resulting in a coverage denial. Insurers could also offer plans with large benefit gaps.  For example, before the ACA introduced the requirement that all plans cover a defined set of basic services, 75 percent of individual market plans excluded maternity coverage, 45 percent excluded substance use treatment, and 38 percent excluded mental health care, according to analysis by the Kaiser Family Foundation. This would leave many people — especially those with pre-existing conditions — without access to the health services they need.

And let’s not forget public health. The ACA’s Prevention and Public Health Fund (PPHF) has become an absolutely critical source of funding for the nation’s public health agencies. Cassidy’s bill would eliminate that fund. Here’s what the Big Cities Health Coalition, a forum for the country’s largest metropolitan health departments, had to say about the fund’s potential elimination:

Among the programs at risk at the CDC are the 317 Immunization Program, Epidemiology and Laboratory Capacity Grants, the Childhood Lead Poisoning Prevention Program, and a host of chronic disease programs. The PPHF provides vital resources to governmental public health at all levels, and its elimination will further erode our fragile health system.

Eliminating public health programs that are now funded by the ACA would seriously undermine the ability of cities and counties to protect and promote health. The loss of hundreds of millions of dollars would hamper efforts to respond to food borne illness outbreaks, prevent emerging infectious diseases like Ebola and Zika, and respond to natural disasters like Hurricanes Irma and Harvey.

And in a letter to senators from the American Public Health Association, Executive Director Georges Benjamin writes:

The Graham-Cassidy plan would also eliminate the Prevention and Public Health Fund, the first and only mandatory funding stream specifically dedicated to public health and prevention activities. The fund has already provided more than $6 billion to support a variety of public health activities in every state including tracking and preventing infectious diseases like the Ebola and Zika viruses, community and clinical prevention programs, preventing childhood lead poisoning and expanding access to childhood immunizations. Eliminating the fund would devastate the budget of the Centers for Disease Control and Prevention. The fund currently makes up 12 percent of CDC’s budget and eliminating this funding stream would force Congress to replace the funding through the regular appropriations process where resources for nondefense discretionary programs are already too low.

Graham-Cassidy-Heller-Johnson is a threat to America’s health. If you’d like to voice your opinion, the American Public Health Association has an easy-to-use template to help you reach your representatives in Congress. For more information on the ACA replacement, NPR has a fantastic explainer.
