Make sure your Medicare provider data is covered as the program undertakes a system transition. Old way: “Historically provider demographic data have been maintained in the Automated Survey Processing Environment or ASPEN software,” the Centers for Medicare & Medicaid Services says in a new message to providers. New way: “CMS will be transitioning to use the demographic information from Provider Enrollment, Chain and Ownership System (PECOS),” the agency explains. “While this transition is underway, a final date when all demographic data will be obtained from PECOS has not been identified.” Meanwhile, “during this transition, all [post-acute] providers will be responsible to ensure their latest demographic data are updated and available in both … iQIES (HHAs and Hospices) and PECOS systems,” CMS instructs.
