The Centers for Medicare & Medicaid Services (CMS) has implemented an Internet-based Medicare provider enrollment process, known as Internet-based Provider Enrollment, Chain and Ownership System (PECOS).
If you are not enrolled in the Medicare program, or if you enrolled more than 5 years ago and have not submitted any updates or changes to your enrollment information in 5 years, you do not have an enrollment record in PECOS.
In order to continue to order DMEPOS for Medicare beneficiaries after January 2011, you will have to enroll in the Medicare program or "revalidate" your Medicare enrollment information. Information about enrolling in Medicare is found on the CMS Web site at http://www.cms.hhs.gov/MedicareProviderSupEnroll
