About half of the enrollments are coming from people who were previously insured and half are not. When I try to gauge this, I go to carriers who had high market share before Obamacare and have maintained that through the first open enrollment. Some carriers have said only a small percentage of their enrollments had coverage before but health plans only would know who they insured before.
By sticking to the high market share carriers who have maintained a stable market share and knowing how many of their customers are repeat buyers, it’s possible to get a better sense for the overall market. Other conventional polls have suggested the repeat buyers are closer to two-thirds of the exchange enrollees.
The number of those in the key 18-34 demographic group improved only slightly during the last month of open enrollment so the average age is still high. The actuaries I talk to think this issue of average age is made to be far more important than it should be. It is better to have a young group than an old group. But remember, the youngest people pay one-third of the premium that older people pay.
The real issue is are we getting a large enough group to get the proper cross section of healthy and sick?
The bigger concern continues to be the relatively small number of previously uninsured people who have signed up compared to the size of the eligible group. The recent report released by Express Scripts reporting on very costly pharmacy claim experience from January and February enrollees is far more concerning than the average age.
