The Obama administration is asking New Jersey to pay back $32 million in Medicare payments that didn't comply with federal law. The improper billing was detailed on Monday in a report by the inspector general for the Department of Health and Human Services. In a random sample of 100 personal care claims, investigators found concerns with 17 of those claims. Those issues ranged from lack of documentation, lack of nursing assessment and no plan of care, according to the report. The sample was a small fraction of the 18 million detailed claims submitted that period by 266 personal care agencies in New Jersey.
