On January 15, 2010, CMS issued a transmittal on “Various OIG Reports that have Medical Review Implications.” The transmittal instructs Medicare contractors to take steps to strengthen program safeguards to prevent improper payment in areas identified by the HHS Office of Inspector General (OIG). Specifically, reports highlighted by CMS address negative pressure wound therapy pumps, ambulance transportation for skilled nursing facility residents, pressure reducing support surfaces, and hospice services. CMS instructs contractors to use the information contained in the OIG reports and follow the processes and procedures already in the Medicare Program Integrity Manual concerning data analysis, contractor strategies, and the progressive corrective action process.
