Medicare spent $47.9 billion in one year for health care treatments and equipment that were not medically necessary, miscoded by providers, or lacked proper documentation.
Only a small amount of the $47.9 billion in improper payments reported in 2010 was due to fraud, according to Daniel Levinson, inspector general for the Health and Human Services Department.
Some 94 percent of the improper payments were made to durable medical equipment suppliers, hospitals, skilled nursing facilities, home health agencies and physicians, Levinson told a U.S. House Oversight and Government Reform subcommittee on Thursday.
For example, 57 percent of claims for wheelchairs were either not medically necessary or did not have the required documentation, he said. As a result, Medicare paid $95 million over a six-month period for wheelchairs that the government insurance plan should not have paid.
Additionally, 60 percent of claims submitted to Medicare for power wheelchairs were not documented properly, resulting in $112 million in improper payments over six months, he said.
The inspector general said his office plans to examine a group of what he described as “error-prone” providers who have submitted a number of incorrect claims in the past four years. The internal watchdog is also taking a closer look at bills submitted by power wheelchair providers, nursing homes, home health care agencies and hospitals to prevent incorrect payments, he said.
