In the absence of a federal commitment to continue funding cost-sharing reduction (CSR) reimbursements through the upcoming year, Covered California health insurance companies will add a surcharge to Silver-tier products in 2018. However, because the surcharge will only be applied to Silver-tier plans, nearly four out of five consumers will see their premiums stay the same or decrease, since the amount of financial help they receive will also rise. Those who do not get financial help will not have to pay a surcharge.
