This regulation outlines requirements for group health plans and health insurance coverage in the group and individual markets for two areas: (1) expansion of coverage of recommended preventive services, and (2) restrictions on or prohibition of the implementation of cost-sharing mechanisms by the insurers (i.e. coinsurance, deductibles and copayments). These requirements generally become effective for plan years (policy years in the individual market) beginning on or after September 23, 2010. A list of recommendations and guidelines for insurers with respect to preventative services is available at: http://www.HealthCare.gov/center/regulations/prevention.html
