The Trump administration will have to consider the impact of repeal on the federal budget, as well as the level of congressional support for repeal and replace. Will there be congressional consensus on all aspects of repeal and replace? Or will some provisions remain in place, such as the ban on pre-existing condition exclusions and coverage of adult children in employer plans to age 26? President-elect Trump recently said he's open to leaving both provisions in place, suggesting that “repeal and replace” might become “amend and modify.”

The Senate's Democrats, who are supporters of the ACA, might attempt to filibuster any attempts to dismantle it. In that event, the Republican majority might attempt to enact changes via the reconciliation process, a complex parliamentary maneuver that limits the kinds of changes that can be made. In addition to political support, the support of health care industry stakeholders, such as employers, providers, insurers, manufacturers of drugs and medical devices and consumer advocates, will be crucial to any significant health care legislation.

The full outline of the Trump administration's plans for health care reform will become clear over the coming weeks and months. Congressional Republicans have already issued a 37-page outline regarding what they view as a possible replacement for the ACA. Changes could include:

• Repeal of the individual and employer mandates. Although these are likely to be the first of the ACA provisions to be targeted, employers should realize that the mandates—and the ACA reporting obligations and penalties—remain on the books.

• Portability of health insurance. Financial support for portable health care coverage, including a universal refundable tax credit for individuals and families to purchase a health care policy;

• Repeal of the Cadillac Tax. Preserving employer-provided health insurance, including a repeal of the Cadillac Tax and enactment of a refundable tax credit coupled with a cap on the employer health care exclusion;

• Medicaid reform. Converting federal Medicaid funding to block grants and ending the expansion of Medicaid under the Affordable Care Act;

• Association health plans. Expanding opportunities for small businesses in voluntary organizations to band together to offer small business health plans;

• Wellness programs. Preserving employee wellness programs and opposing EEOC regulations that hinder and obstruct their implementation;

• Stop loss insurance. Preserving the current definition of stop loss insurance; and

• Liability reform. Medical liability reform including caps on non-economic damages and adoption of the loser pays rule.

Other possible health care reforms

Congress may also consider the following proposals from the Trump campaign in the coming year:

• Allowing all individuals to deduct health insurance premiums paid on a post- tax basis;

• Negotiating Medicare prescription drug prices;

• Removing barriers to entry into free markets for drug providers that offer safe, reliable and cheaper products; and

• Revising and possibly withdrawing the contraceptive regulations for religious organizations.

How quickly all of this — or any of it — can be accomplished will be one of the first tests of the new president's administration.

For now, the status quo remains. The employer mandate to offer affordable, minimum value health insurance to full-time employees stays in effect with all its compliance and reporting obligations for the 2016 year, including the requirement to file Forms 1094 and 1095 in early 2017.

The individual mandate to carry health insurance or pay a penalty also remains in effect. The public exchanges, which cover almost 13 million people and subsidize coverage for 85 percent of those enrollees, are conducting open enrollment for 2017 and have seen a surge of enrollment immediately following the election. Employers are likely to continue staying the course as things shake out in Washington.

Will he or won't he?

In his first televised statements since winning the presidential election on Nov. 8th, President-elect Donald Trump stepped back from his pledge to completely repeal and replace the Affordable Care Act. During a 60 Minutes interview with CBS News' Lesley Stahl, Trump expanded on his health care plans, noting he definitely wants “to focus on health care” once he takes office.

Stahl: Let me ask you about Obamacare, which you say you're going to repeal and replace. When you replace it, are you going to make sure that people with pre-existing conditions are still covered?

Trump: Yes. Because it happens to be one of the strongest assets.

Stahl: So you're going to keep that?

Trump: Also, with children living with their parents for an extended period, we're gonna—

Stahl: You're gonna keep that—

Trump: Very much try and keep that. Adds cost, but it's very much something we're going to try and keep.

Coverage for those with preexisting health conditions and allowing children to remain on their parents health insurance plans until the age of 26 are two of the ACA's most popular mandates.

Stahl: And there's going to be a period if you repeal it and before you replace it when millions of people could lose – no?

Trump: No, we're going to do it simultaneously. It'll be just fine. We're not going to have, like, a two-day period and we're not going to have a two-year period where there's nothing. It will be repealed and replaced. And we'll know. And it'll be great health care for much less money. So it'll be better health care, much better, for less money. Not a bad combination.

Experts have estimated Trump's health care plan would leave anywhere from 18 million to 25 million Americans uninsured.
