The document discusses how the Affordable Care Act's essential health benefits provisions will expand coverage in the individual insurance market beginning in 2014. It finds that millions of Americans will gain access to important benefits not currently covered by many individual plans. Specifically, it estimates that 8.7 million will gain maternity coverage, 4.8 million substance abuse coverage, 2.3 million mental health coverage, and 1.3 million prescription drug coverage. This expansion of benefits will occur as insurance plans in the individual market are now required under the ACA to cover ten essential health benefit categories.
