HHS: Seniors have saved $7 billion on drugs thanks to ObamaCare

The healthcare law gradually closes the Medicare "doughnut hole," which required seniors to pay for their drugs out-of-pocket after they had spent a certain amount in one year. 

The law also added new benefits for preventive care, and 16.5 million seniors have used at least one of those services since the law took effect.

“Medicare is much stronger as a result of the healthcare law,” said HHS Secretary Kathleen SebeliusKathleen SebeliusThe House needs to help patients from being victimized by antiquated technology Obama cabinet official: Clinton White House doubled down on 'abusive behavior' John Roberts has tough job of keeping faith in Supreme Court MORE. “Spending has slowed to historic levels as seniors are enjoying enhanced benefits and greater savings on drugs.”
