What is a Silver plan?
Under the Affordable Care Act, individual/family (self-purchased) and small-group health insurance plans are classified by metal levels: Bronze, Silver, Gold, and Platinum.
The classification depends on the actuarial value (AV) of the plan, which measures the percentage of medical costs that the plan would cover for a standard population.
Silver plans have an actuarial value of about 70%, although there's a small de minimus range allowed: Silver plan AV can range from 68% to 72% in the small group market, and from 70% to 72% in the individual/family market.1
But the ACA's cost-sharing reductions (CSR, also called cost-sharing subsidies) are only available on Silver plans. If a person qualifies for CSR benefits and selects a Silver plan, the plan's actuarial value will be increased to 73%, 87%, or 94%, depending on the person's household income. This can essentially result in a Silver plan that provides more robust coverage than a Gold or even Platinum plan, depending on the enrollee's income.
Silver plans play a particularly important role in the individual health insurance market. The ACA's premium subsidies (premium tax credits) are based on the cost of the benchmark plan, which is defined as the second-lowest-cost Silver plan in a given area. (Subsidies can be used to offset the cost of any metal-level plan.)
How many Marketplace enrollees have Silver plans?
