Submitting the CMS-855 Enrollment Application and Billing Effective Date Changes
As of May 14, 2012, the billing effective date can be made retroactive as far back as 30 calendar days from the date the application was received in Medicare's office.
Provider offices must submit the CMS 855 form as soon as the provider begins seeing Medicare patients to ensure their services will be processed by Medicare. With CR7797, the CM-855 form can be now submitted up to 60 days in advance of the provider seeing Medicare patients.
Providers that get Medicare certification (such as Ambulatory Surgery Centers and Portable X-ray suppliers) can submit their applications up to 180 days in advance of seeing Medicare patients. To expedite the application process, the application can be submitted online at https://pecos.cms.hhs.gov/pecos/login.do on the CMS website also known as "Internet Based Provider Enrollment, Chain and Ownership System (PECOS).
"The effective date of an online application can be made retroactive as far back as 30 calendar days from the date the printed certification statement is received in our office. Providers may also use the e-signature option for PECOS web applications".
