Now that the Supreme Court has upheld the Patient Protection and Affordable Care Act along with the individual mandate, it's time for employers to start preparing for upcoming compliance issues, says Janet Trautwein, executive vice president and CEO of National Association of Health Underwriters.

While certain provisions of PPACA have already been implemented, such as the new limits on coverage for over-the-counter drugs and medical-loss ratio requirements, there are certain mandates that are set to go into effect this year, and employers need to be ready for those changes, Trautwein says. Specifically, employers should be focusing on complying with the reporting the value of employer-provided health insurance on W-2 forms, which is one of the big changes in 2012.

While reporting for 2011 is voluntary, employers must include the value of group health plan coverage on W-2s issued after Jan. 1, 2013; however, there are exceptions to this rule Trautwein says. Employers that issue fewer than 250 W-2 forms per year are exempt, but that does not necessarily equate to 250 employees.
