One of the effects of the Patient Protection and Affordable Care Act (PPACA) has already surfaced: some companies, preferring not to tangle with the new law’s requirements or consequences, have bowed out.

First it was reported by NU Online News Service that some health insurers are dropping child-only policies, and now a company is shedding its health insurance division altogether.

Delaware Insurance Commissioner Karin Weldin Stewart on Thursday became the latest state official to meet with insurers regarding the decision of several major companies to stop offering new child-only policies in the wake of PPACA’s requirement that children cannot be denied coverage due to pre-existing conditions. Companies fear that parents will abstain from insuring their children until they are very ill, resulting in high claims and expenses. That provision of the law took effect on Sept. 23.

Another piece of fallout from the new law is the exit of Principal Financial Group from the health insurance business. On Thursday, also reported by NU Online News Service, it was announced that the company, which primarily focuses on asset management, will no longer offer health insurance and will turn over its current health insurance customers to UnitedHealth Group. The company says that it has no economies of scale to enable it to remain competitive.
