Rating system for Medicare Advantage plans is flawed; changes are planned
Tuesday, June 15, 2010
For consumers looking for bargains on refrigerators or restaurants, ratings can be helpful. But a score card doesn't work as well for selecting a Medicare private health plan.
About 47 million people are in Medicare, the federal health program for the elderly and disabled; nearly a quarter of them are enrolled in Medicare Advantage plans, offered by insurance companies as alternatives to the traditional program. The plans, which receive federal subsidies, offer Medicare's standard benefits plus extra benefits, often including prescription drug coverage. A few years ago, federal officials began rating these plans -- using a scale of one to five stars -- but seniors' advocates, policy analysts, insurers and some top Medicare officials agree the ratings are flawed.
Even so, the star system is about to become more significant.
Under the new health-care overhaul law, the ratings will be used for the first time to award bonuses potentially worth hundreds of millions of dollars to the best plans. If the bonuses had been in effect last year, the top-rated plans would have received a total of $1.3 billion, estimates Brian Biles, a health policy professor at George Washington University.
Seniors don't seem to pay much attention to the ratings. Beneficiaries tend to pick Medicare Advantage plans based on cost and access to their doctors, not ratings, says Jonathan Blum, deputy administrator for the Centers for Medicare and Medicaid Services, or CMS. More than 75 percent of the plans' members choose plans with three or fewer stars.
But many don't have much choice: Biles found that only 15 percent of Medicare Advantage members live in counties where four- or five-star plans are offered.
In a new study, Avalere Health, a consulting firm, found that only 5 percent of Medicare Advantage members in Virginia are in four-star plans. That compares with 33 percent in Maryland and 68 percent in the District. And no one in the Washington area is enrolled in a five-star plan, for a good reason: None of the plans offered here has earned the top grade.
Although the scores are updated every fall, some are based on information that is almost two years old. More than 40 percent of plans have no rating because they are too new or too small, according to studies by the Kaiser Family Foundation and Avalere.
To fix some of the ratings' shortcomings, CMS will propose changes this summer, says Blum. "We will start off with the system we have," he says. "But I fully expect that it will change over time."
The ratings' flaws were underscored in April, when Medicare ordered Aetna, one of the nation's top health insurers, to suspend enrollment in its Medicare Advantage and stand-alone Medicare prescription-drug plans. Medicare's compliance officer told Aetna that a delay in the plans' approval of the filling of prescriptions "potentially puts Aetna's current and future enrollees' heath at risk." Yet when the decision was announced, Aetna's most expensive Medicare Advantage plan in Northern Virginia was rated at 3 1/2 stars -- between "good" and "very good." An Aetna official said the rating makes sense because drug-coverage performance is only one of many criteria used to determine rankings.
Under the Medicare Advantage program, the government pays the plans a set amount for each beneficiary -- an average of 13 percent, or about $1,140 in 2009 -- above what the original Medicare program spends on a similar individual. Some plans use the money to offer extra benefits such as dental care, eyeglasses and gym memberships, often at no additional expense to the beneficiary. The health-care law phases out these extra payments beginning in 2011. That change, which would probably force many Advantage plans to trim their extra benefits, may make the plans less attractive to many people.
Medicare Advantage ratings are currently based on 33 criteria, including members' satisfaction, customer service and how often members get screenings and tests. Plans that also offer drug coverage are graded in 19 additional areas. A summary or average of the results for each plan appears on the "Medicare Options Compare" Web site (go to http:/
