Here's the lowdown on how these CMS changes apply to your practice. If you're a rural healthcare provider, you'll want to know the latest news CMS officials discussed during an Open Door Forum call on October 18. Read on for a few highlights about revalidation letters that your practice might need to know. Watch for Your Revalidation Letter From CMS As part of the Patient Care and Affordable Care Act (section 6401(a)), all new and existing Medicare providers must be reevaluated under new screening criteria that went into effect March 25, 2011. All enrolled providers and suppliers must revalidate their enrollment information every five years, to ensure that Medicare has the most current information on file. "If your physician is newly enrolled on or after March 25, 2011, you're not affected by this effort," Sabeen Chong, CPI, said during the call. Revalidation letters will be sent on a regular basis over the next year or more. "Phase one is in effect, and the first group of providers and suppliers have received their letters," Chong said. Consequence: "Don't try to revalidate until you hear from your contractor," Chong warned. "If you respond in a timely manner once you hear from the contractor, it shouldn't interrupt your payment cycle." Providers and suppliers can enroll in the Medicare program by paper application or by using the Internet-based Provider Enrollment, Chain, and Ownership System (PECOS). Follow up: So, while you are waiting for your letter, check the list periodically (once a month or so) to see if it's been mailed and keep your eyes open for such a letter from your MAC. When you do receive your letter, respond promptly (i.e., within 60 days) by completing the necessary enrollment application, either virtually in PECOS or on paper, if necessary. If you're on the list and have not received your letter, then contact your MAC immediately for more information on what you should do and ask them to possibly fax or e-mail you a copy of the letter in this regard.
