Health insurers still seek steep premium increases

Rates going up fastest in states with weaker rules

NEW YORK — Health insurance companies across the country are seeking and winning double-digit increases in premiums for some customers, even though one of the biggest objectives of the Obama administration’s health care law was to stem the rapid rise in insurance costs for consumers.

Particularly vulnerable to the high rates are small businesses and people who do not have employer-provided insurance and must buy it on their own.

In California, Aetna is proposing rate increases of as much as 22 percent, Anthem Blue Cross 26 percent and Blue Shield of California 20 percent for some of their policy holders, according to the insurers’ filings with the state for 2013.

The rate requests in California are all the more striking after a 39 percent increase sought by Anthem Blue Cross in 2010 helped give impetus to the law, known as the Affordable Care Act, which was passed two years ago.

In other states, such as Florida and Ohio, insurers have been able to raise rates by at least 20 percent for some policy holders. The rate increases can amount to several hundred dollars a month.

The proposed increases compare with about 4 percent for families with employer-based policies.

Under the health care law, regulators are now required to review any request for a rate increase of 10 percent or more; the requests are posted on a federal website, healthcare.gov, along with regulators’ evaluations.

The review process not only reveals the sharp disparity in the rates themselves, it also demonstrates the striking difference between places like New York, one of the 37 states where legislatures have given regulators some authority to deny or roll back rates deemed excessive, and California, which is among the states that do not have that ability.

New York, for example, recently used its sweeping powers to hold rate increases for 2013 in the individual and small-group markets to under 10 percent. California can review rate requests for technical errors but cannot deny rate increases.

In Massachusetts, state regulators in November approved health insurance rates that will boost premiums for small businesses and individuals an average of 3.6 percent in the first quarter of 2013, continuing an increase in rates that began over the summer.

Among the large commercial insurers, rates will rise by 6.9 percent for Blue Cross Blue Shield of Massachusetts and 3.4 percent for its HMO business, 3.9 percent for Harvard Pilgrim Health Care and 4.7 percent for its HMO business, 2.2 percent for Tufts Health Plan and 2.6 percent for its HMO business, and 0.4 percent for Fallon Community Health Plan and its HMO business.

The double-digit requests in some states are being made despite evidence that overall health care costs appear to have slowed in recent years, increasing in the single digits annually as many people put off treatment because of the weak economy. PricewaterhouseCoopers estimates that costs may increase just 7.5 percent next year, well below the rate increases being sought by some insurers.

But the companies counter that medical costs for some policy holders are rising much faster than the average, suggesting they are in a sicker population. Federal regulators contend that premiums would be higher still without the law, which also sets limits on profits and administrative costs and provides for rebates if insurers exceed those limits.

Critics, like Dave Jones, the California insurance commissioner and one of two health plan regulators in that state, said that without a federal provision giving all regulators the ability to deny excessive rate increases, some insurance companies can raise rates as much as they did before the law was enacted.

‘‘This is business as usual,’’ Jones said. ‘‘It’s a huge loophole in the Affordable Care Act.”
