Novice Know How - Requirements for Provider Changes to Provider Enrollment Information
The Centers for Medicare & Medicaid Services (CMS) requires that a provider must notify Medicare of certain Provider Enrollment information changes within 90 days.
In order to prevent a Do Not Forward (DNF) flag from being added to a provider file, a provider must promptly report Special Payments address and/or Bank Routing/Account number change(s) to the carrier's Provider Enrollment department. Medicare cannot forward checks and Remittance Notices if a provider's file is flagged with DNF. Once effectuated, a DNF Flag cannot be removed from the provider's file until a CMS Form 855 application is received to notify Medicare of the updates.
At this time, CMS requires that any individual, group, or organization making a change to their pay-to address (Special Payments address) without an initial enrollment application (CMS Form 855) on file must complete one in its entirety before a change is made to a pay-to address. For example, if you or your organization enrolled prior to 1998, this may affect you.
An individual solo practitioner must complete a CMS Form 855I for any of the following changes to his/her 'Individual Medicare file':
- Name changes/updates (marriage, divorce or legal name change)
- Address additions/deletions
- Adding/changing a Billing Agency
- Changing/updating the provider specialty
- Changing/updating an effective date or termination date
An organization must complete the CMS 855B for the following changes to their 'Organization/Group Medicare file':
- Changing/updating an effective date or termination date
- Address additions/deletions
- Adding/changing a Billing Agency
- Changing/Deleting the Authorized Official
- Changing/Deleting the Delegated Official
- Terming a Physician Assistant PIN within your group
Group members must complete the CMS Form 855R to make the following changes to their reassignment:
- Terminate a current Reassignment
- Change the effective date/termination date on a reassignment
