However, the Supreme Court agreed to hear arguments on several of its core issues in March. The court may rule on the issues by the end of this month.Basics: Health care reform issuesNo matter the ruling, most Americans will be affected.

The decision will have an immediate and long-term impact on all Americans, both in how they get medicine and health care.cnnArticleGallery.currentImageList[cnnArticleGallery.currentImageList.length] = {"currentPicture":false,"x":5,"y":1,"pos":12,"title":"Health care and the high court"} Health care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high courtHealth care and the high court Photos: Health care and the high court Event.observe(window, 'load', function() {//report the first gallery image to ADBPif(typeof(cnn_adbptrackpgalimg) == 'function' && typeof(cnnArticleGallery) != 'undefined') {cnn_adbptrackpgalimg(cnnArticleGallery.currentImageList[0].image, "");}});Business owners One hundred and sixty million Americans receive health care from their employers, many of whom set their own rates for their employees. If the court rules against the act, employees might face higher premiums, fewer network providers, higher-deductible plans and more stringent regulations on adding adult dependents.What is Corporate America's Plan B to safeguard employees and industry if the act is struck down? Here are some insights:Employers' 'plan B' if health reform is axedEmployers bear brunt of health insurance hikesSmall business ownersIf you run your own company, the act has a lot of good in store for you -- that is, if you know how to access it. Many small business owners across the country who do offer health coverage haven't taken advantage of, or didn't even know about, a tax credit that helps offset giving employees insurance.Why wouldn't small business owners take advantage of this? CNNMoney answers that question and talks about what might happen if only parts of the act are kept:The health care tax credit few are takingWhat's at stake for small businessesNational spendingBeing insured helps safeguard against pricey medical bills. However, a report released Tuesday from the Centers for Medicare and Medicaid Services suggests that the act won't limit national health spending. In fact, it predicts that spending will skyrocket after a brief recession-induced dip.Growth in health spending doesn't necessarily correlate with growth in health care costs, but what does it mean? Here's a projection:Health spending growth to stay low, then jumpAmerica's youthFor today's young adults, health care comes last. If you can't afford to feed and clothe yourself, why budget for something that hasn't happened yet? However, youth get sick too, and their future bank accounts might take a toll if the act is repealed -- or if they don't insure themselves, period. Additionally, the ones who do insure themselves tend to forgo expenditures elsewhere (like graduate school) to make ends meet.Young adults skip health care as medical debts riseFor 20-somethings, health care hangs in the balanceSenior citizensHealth reform has been the belle of the senior citizen community, saving Medicare beneficiaries a collective $3.7 billion dollars on their medication costs since its inception in 2010. One of the reform's aims is to close the "donut hole," or portion of senior citizens that can't pay for medication out of pocket, by 2020.Read how Medicare has been affected by health care reform:Medicare: Seniors saved $3.7 billion on medicineDoctors at riskIncreases in insurance coverage and changes in Medicare help patients avoid footing hefty medical bills, but sometimes their doctors pay the price.Read why some doctors, especially those in private practice, are running out of money:Doctors going brokeDoctors: We could go out of businessSilver liningsJust because a negative ruling would give health insurers and states the ability to opt out of reform-era options doesn't mean they're going to. UnitedHealthcare, the nation's largest health insurer, said that while it will take cues from competitors, it will maintain some of the act's key mandates regardless of the court's decision. Moreover, there is strong bipartisan support for state-created health care exchange programs, many of which have been set into motion, where those seeking insurance can look for subsidized coverage.UnitedHealthcare to keep some health care mandatesExchanges could survive even if health reform law diesThe fine printVery few people take the time to read bills in their entirety, but should we?
