We are getting closer and closer to a decision on the constitutionality of the health reform law. The Supreme Court of the United States is slated to announce their decision in late June. Clearly, the issue of health reform is highly contested and some seem just dead against it.

However, there are certain aspects of the Patient Protection and Affordable Care Act (PPACA), some of which have already gone into effect, that are just plain popular. For instance, since 2010, young adults under the age of 26 have been allowed to stay on their parents’ health insurance policy. With 6.6 million young people taking advantage of this, it’s fair to say that the law has been well-received.

So, what happens if the Supreme Court tosses the whole thing out? Well, three of the nation’s largest health insurance carriers have an answer to that question, and it might surprise you.

UnitedHealthcare, Humana and Aetna have pledged that regardless of the Supreme Court’s decision, they will voluntarily honor certain key provisions of the PPACA.

It will be interesting to see how things play out from here. Will other health insurance carriers follow the lead of these three giants in the industry? Will it all be an empty gesture because health reform is going to pass?

All of these questions and more will be answered once we finally get that final ruling from the Supreme Court. And undoubtedly, a whole new set of questions will arise. Stay tuned.
