This form is essential for clinics and group practices intending to bill Medicare for Part B services, ensuring that all necessary details are captured accurately.

The purpose of the Medicare Enrollment Application (CMS-855B) is for clinics, group practices, and other medical suppliers in the US to enroll in Medicare to bill for Part B services. This application is used for initial enrollment, revalidation, reactivation, or to report changes of information. It allows an organization to bill Medicare, rather than having each practitioner bill individually. The form collects comprehensive details on the organization, including ownership, practice locations, and managing control, to ensure operational clarity and facilitate a smooth enrollment process.
Practice managers and credentialing staff typically prepare the Medicare Enrollment Application (CMS-855B), but an Authorized Official of the organization must sign the final certification. This official is someone with the legal authority to bind the organization, such as a CEO, CFO, general partner, or direct owner. While you may prepare the application, the Authorized Official's signature is non-delegable. Once delegation is established, a Delegated Official, who must be a W-2 managing employee or have an ownership interest, can make subsequent changes to the enrollment information.
A Medicare Enrollment Application (CMS-855B) includes detailed information about your organization's business, locations, ownership, and any adverse legal history.
The application includes a matrix detailing which sections you must complete based on the reason for submission, such as an initial enrollment versus a change of information. This matrix is several pages long and complex. It is a common friction point to miss a required subsection for your specific reporting scenario. An incomplete submission based on this matrix will cause the Medicare Administrative Contractor (MAC) to return the application unprocessed, delaying your enrollment or update.
Your organization's Legal Business Name and Taxpayer Identification Number (TIN) must exactly match the records held by the IRS and your organization's NPI record. Any small drift, such as using a DBA instead of the legal name or having a typo, will cause the MAC to return the application. This requires careful verification against official IRS documentation before submission to avoid automatic rejections and the associated administrative rework.
The Final Adverse Legal Actions section requires reporting every relevant event for the organization and all key personnel within the preceding 10 years. This includes events for all 5%+ owners, officers, directors, and managing employees, regardless of whether records were expunged or appeals are pending. Under-reporting in this section is the leading cause of post-enrollment revocation, making it a high-stakes area that requires meticulous and comprehensive information gathering across your entire leadership team.
That frustrating rule where your Legal Business Name and TIN must exactly match IRS records is a common reason for returned applications. Heidi pre-populates your organization’s identifiers, including your LBN and TIN, from your structured profile. It cross-checks them against your official tax records to prevent mismatches that trigger a return. Heidi also pulls forward details like practice locations from previous filings, saving you from re-entering the same information.
Instead of you manually navigating the complex "Required Sections" matrix to figure out what to fill in, Heidi does it for you. Based on the change you are reporting, Heidi surfaces only the specific sections required for that submission type. This ensures you complete all necessary parts of the 48-page document without missing a required sub-section, which helps prevent the MAC from returning the application unprocessed. You review the selected sections as a starting point.
Under-reporting of adverse legal actions is the leading cause of post-enrollment revocation. Heidi surfaces the 10-year lookback window for every owner, officer, director, and managing employee in your organization. It then prompts each person for a positive or negative response, ensuring every required individual attests to their history. This helps catch potential omissions during preparation, giving you a more complete application for your final review and signature.
