What is Cost-Sharing Reductions

Cost sharing reductions are a type of federal subsidy distributed as discounts that help reduce out-of-pocket costs for health-care expenses, including:

  • Deductibles – the amount you owe for covered services before insurance kicks in;
  • Copayments – a fixed amount you pay for covered health-care services; and
  • Coinsurance – your share of the costs of covered health-care services.

The cost-sharing reduction subsidy was a provision in the Patient Protection and Affordable Care Act, signed into law on March 23, 2010 by President Barack Obama.
