Provider Enrollment - Forms

The NHIC Provider Enrollment Unit is charged with the responsibility to accept, validate, and process Medicare provider enrollment applications within its jurisdiction. These pages will assist you in all phases of provider enrollment.

Application Forms

To enroll in Medicare as a provider or make changes to your existing Medicare information, you must complete a CMS-855 application.

The CMS-855 Medicare enrollment applications located on the CMS forms web page can be completed on-line in a PDF fillable format or downloaded and completed by hand.

A comprehensive user guide, providing detailed instructions on how to download and complete each of the three application forms, is also available on the CMS Web site.

If a provider wants to enroll as a Participating Provider (PAR), the Participation Provider Agreement (CMS-460) must be included with the enrollment application.

Choosing a Form

Individual Practitioners

All solo providers, who are not incorporated, must complete the CMS 855I even if they previously had a group member or individual number in the state. New providers should attach a copy of their license and medical diploma. Individuals working under a tax identification number must include a copy of the entity's IRS Form CP575.

Providers Applying as a Group

Whenever two or more providers work under the same tax identification number, they must form a group. The group number is like an umbrella the group members' numbers fall under. To create a group, complete the CMS 855B.

Attach a copy of the applicant's IRS Form CP575, and make sure the authorized official signs Section 15, the certification statement. Include a minimum of one group member's application with this group application.

To enroll a group member, complete the CMS 855R. If the provider has not previously had a Medicare provider number within the jurisdiction of NHIC, they must also complete the CMS 855I. Include copy of the member's state license and medical diploma.

Incorporated Providers - Using a Fictitious Name

Incorporated providers must complete additional CMS application forms. If you are not currently enrolled with NHIC, the first application, the CMS 855I, will be used to establish you with the Medicare program. Secondly, the CMS 855B is completed in order to enroll your business. Additionally, the CMS 855R is completed in order to reassign benefits payable to you as an individual practitioner to your business, which will be submitting claims for the services rendered.

In addition, any other practitioners who render services for your business, and who will be reassigning their benefits to the business, must also complete a CMS 855R.

Incorporated Individual Providers - Using First and Last Name

Incorporated individuals using their fist and last name must complete the CMS 855I application.

In addition, any other practitioners who render services for your business, and who will be reassigning their benefits to the business, must also complete a CMS 855R.

Provider Benefits Reassignment

Every provider or entity that wants to receive benefits that have been reassigned to them must be enrolled in the Medicare program. For example, if a hospital wants to receive benefits reassigned by a contracting physician, the hospital must be enrolled in Medicare Part B.  The hospital must therefore complete CMS 855B. Each member of the group who is NOT a current Medicare provider will complete CMS 855I; but those who are already established Medicare providers will only complete CMS 855R.
