CMS 855A: Medicare Enrollment Application - Institutional Providers
CMS has developed a Provider Enrollment brochure and they have placed it on their website. This brochure is informational for new Medicare Providers, and also for Medicare providers who want to understand more about the enrollment process.
Use of 9-digit zip codes for the 855A application
Effective 07/01/07, all providers must include a valid 9-digit zip code on section 4a (practice location) of the CMS 855A application form for any application type submitted.
If a provider's claim is RTP'd for an invalid 9-digit zip code, the provider must submit an 855A application with a valid 9-digit zip code for the facility's practice location.
Please note: If we do not have a current 855A application on file, a provider will be required to submit all sections of the 855A application in order to process the necessary changes.
