People were told if they liked the health plan they have, they can keep it. But that appears not to be the case. Come September, more than 1 million people with “limited-benefit” health plans could join the ranks of the uninsured. Limited benefit plans — sometime called mini-meds — have much lower premiums because potential claims are capped at lower levels than traditional plans and there are often limits on physician visits and drug benefits. Under the new health reform law, insurers will no longer be allowed to offer annual limits on claims in return for lower premiums. Even though the individual mandate is not slated to begin until 2014, many of the low-cost plans will disappear long before then.
