So Far, Exchange Strengthens Market Position of Large Plans
The Affordable Care Act's insurance exchanges were supposed to open up the market -- "more choices, greater competition," trumpets a 2010 White House fact sheet. The exchanges were a rare Obamacare idea that have enjoyed consistent Republican support. And several experts told California Healthline in July that Valley and other small health plans were the ones to watch in California's exchange.
But what if the exchanges are leading to market consolidation, not competition? It seems premature to ask, but here's a picture of the Covered California market from October:
- 28 percent of customers picked Anthem plans;
- 26 percent picked Kaiser Permanente plans;
- 26 percent picked Blue Shield of California plans; and
- 16 percent picked Health Net plans.
That means that fewer than 4 percent of customers were divvied up between the other seven plans currently available on the exchange.
It's worth repeating: Unlike smaller plans -- like Valley, Sharp and a few others that only focused on a slice of California's population -- the "big four" issuers chose to offer plans across the state. Their broader presence helped goose their enrollment numbers.
But that alone can't explain customers' shopping patterns, because similar proportions show up when drilling down into individual regions.
- In October, Valley captured about 2 percent of new Covered California customers in Santa Clara County; the other 98 percent were split between the big four.
- Contra Costa Health Plan got about 4 percent of the new customers in its county; the rest went with the big four.
- Western Health Advantage saw fewer than 2 percent of new customers in the North Bay and Sacramento Valley regions, while the remainder were split between Anthem, Kaiser and Blue Shield. (Health Net isn't offering plans in those regions).
Three Drivers of Customer Behavior
So why the market dominance by the large issuers? Experts suggest a few factors.
The power of name recognition: The big four plans presently command more than 80 percent of the individual insurance market in California. "One might expect [the large plans] to have an even bigger advantage early on due to their recognized brands and marketing muscle," Kaiser Family Foundation's Larry Levitt told California Healthline via email.
The power of being an ex-customer: Some new plan members are very recent old members; officials at several plans suggested that more than 10 percent of new enrollees were former customers. So while most of the sign-ups may be with the major plans like Anthem and Kaiser, most of the plan cancellations have been with them, too.
Challenges with the website: The lack of plan quality ratings and provider directories may have hindered head-to-head comparisons -- even as cautious insurers delayed their marketing campaigns -- again leading customers to stick with names that may have been familiar.
Meanwhile, price was expected to be a lever for consumer choice -- that was the case in Massachusetts, at least. But so far, it's unclear whether it's being weighted as heavily in California. In several regions, there didn't appear to be much correlation between plan prices and sign-ups.
Still, it's "way too early to read too much into the early enrollment numbers," Micah Weinberg of the Bay Area Council said.
The October sign-ups weren't representative of Covered California's expected, and eventual, pool of customers, Weinberg pointed out. Look at the huge percentage of non-subsidized customers, who out-numbered subsidized customers by about five-to-one, he noted. Or the lack of Spanish-speaking customers, who made up just 3 percent of enrollees in October but represent 60% of the state's uninsured population, Anna Gorman reports at Kaiser Health News.
"The population that's enrolled to date, as far as we understand, is a population with greater health care needs," Weinberg added.
"So they may be more likely to go with what they know, or go with the sort of well-known needs."
"But we'll know a lot more later on," Weinberg predicted.
Will Small Plans Stick it Out?
Weinberg and others also raise the question of whether more plans are necessarily better for consumers. Some studies have suggested that just three-to-four insurers are enough to make a region competitive, although exchange rates significantly fall as the number of competitors rises.
Would the smaller plans drop out if they don't get enough customers? That's unlikely, experts and historical evidence suggest.
"I suspect there is a volume level at which a plan would decide it's not worth the administrative expense associated with participating," Kaiser's Levitt muses, "but I imagine that's pretty low. Probably the bigger issue is in putting together a provider network ... [with] a whole-new provider network, the economics may not work at low volumes."
And exchanges can lead to disproportionate enrollment gains for their smaller plans -- eventually. In Massachusetts, Neighborhood Health Plan saw its enrollment nearly double to about 230,000 between 2006 and 2011, largely attributable to the state's new mandate and insurance exchange.
Meanwhile, Blue Cross Blue Shield of Massachusetts -- the state's largest insurer by number of members -- saw the biggest decline in market share across that period, losing about 175,000 enrollees even as other plans added more than 500,000.
"Overall, the Health Connector has spurred competition and created an efficient distribution model for smaller plans and new offerings," according to David Williams, president of the Massachusetts-based Health Business Group. "And new plans are [still] signing up," he added, noting that two more issuers are joining the state's exchange in 2013 and 2014.
Signs of Success
There has been some attrition. Two smaller plans that were initially accepted into Covered California -- Ventura County and Alameda Alliance -- ended up not participating in the exchange's first year.
But for at least one local insurer, there are signs of success.
The Chinese Community Health Plan, which is offering plans in the San Francisco and San Mateo regions, had targeted 4,950 new members by the end of March 2014 open enrollment, spokesperson YoungSoo Cho told California Healthline. (The plan had a total of 15,363 members before Covered California opened for business.)
In October, the plan signed up 216 customers through Covered California -- roughly 12 percent of all new enrollees in the two regions it serves -- using a strategy that combines raising awareness, a targeted enrollment push, and five in-person enrollment centers, Cho says.
And the pace is picking up; sign-ups for the Chinese Community Health Plan nearly quadrupled in November.
