Some Critical Access Hospitals Overpaid by Medicare?

And another report from the HHS Office of Inspector General,  Medicare Part B Overpaid and Beneficiaries Incurred Cost-Share Overcharges of Over $1 Million for the Same Professional Services.  Here is their findings:

Not all Medicare Part B payments made to CAHs for professional services and payments made to health care practitioners complied with Federal requirements. For the 40,026 claims we audited, CAHs and health care practitioners each submitted an equal number of claims. However, for each date of service, only one of the claims complied with Federal requirements. As a result, Medicare administrative contractors (MACs) paid providers $907,438 more than they should have been paid, and beneficiaries were held responsible for $281,321 more than they should have been.

These overpayments occurred because CMS did not have claim system edits to prevent and detect duplicate professional services claims for the same date of service, beneficiary, and procedure.
