How to change or add a practice mailing address

All changes of practice addresses are reported on the applicable CMS-855 form. 

Changes can include but are not limited to adding a new location, moving to a new location, or changing the suite number of current location. 

The CMS-855 form has been created in three formats to address the needs of the individual providers, groups or organizations, and Part A providers:

• The 855I is designed for the individual provider.
• The 855B is designed for groups and organizations.
• The 855A is designed for Part A providers. 

Please select the appropriate step-by-step tutorial below for instructions on changing a practice address using the applicable CMS-855 form:

• Change of practice address for individual Part B providers using the Medicare Enrollment Application - Physicians and Non-Physician Practitioners (CMS-855I)
• Tutorial: Change of Practice Address for Part B Group/Organization Providers (Using CMS-855B)
• Tutorial: Change of Practice Address for Part A Providers (Using CMS-855A)

Our Enrollment Gateway allows you the option to upload your paper enrollment application instead of mailing. For more information, please refer to our Enrollment Gateway User Guide.
