While many people are seeing significant increases in their health care costs and longer lines at the doctor’s office, one group of Americans are reaping the benefits of President Obama’s signature health care law — and not in the way you’d think.

The Washington Examiner‘s Paul Bedard explains:

The one new group already using Obamacare — older children up to age 26 added to their parents’ insurance — are fueling a surge in coverage for pregnancy, substance abuse and depression far greater than young adults who were already covered by mom and dad, according to a new study.

The survey of the Patient Protection and Affordable Care Act’s popular provision that requires employers to extend coverage to children found at one huge employer that the three treatments account for 60 percent of hospital claims for the young adults who signed up in 2011 under Obamacare.

The Employee Benefit Research Institute said that is nearly double the number of claims by young adults who were already enrolled in their parents’ plan before the provision went into effect in 2011. The study said that substance abuse, pregnancy and mental illness accounted for about a third of the claims for that group.
