It is in the realm of actuarial value (AV) requirements where the law demands pointless standardization. AV measures the extent to which a policy covers the average enrollee’s medical expenses. On average, for example, a plan with an AV of 63 percent covers 63 percent of enrollees’ medical costs.
All ACA-compliant plans must fit within four “metallic” bands. A platinum plan covers around 90 percent of an enrollee’s costs, with a 2 percent tolerance in either direction. Thus, a platinum plan covers between 88 and 92 percent of costs. A less expensive gold plan covers between 78 and 82 percent of expenses. A silver plan’s AV falls between 68 and 72 percent. Finally, bronze plans cover between 58 and 62 percent.
A plan offered in 2013 can have any AV, but come January 1, 2014, all plans must fall within those four narrow metallic bands. Therefore, a plan that covers 59 percent of medical expenses is okay, because it’s within the bronze band. But a plan that covers 96 percent of expenses is unacceptable because its coverage is too generous; it is, by official rhetoric, subpar, substandard, bad insurance.
