Step By Step Instructions For Medicare Enrollment

Medicare is a federal health insurance program in the United States that primarily serves individuals aged 65 and older, although some younger individuals with certain disabilities or medical conditions may also qualify. It is administered by the Centers for Medicare & Medicaid Services (CMS) and provides coverage for hospital stays, outpatient care, prescription drugs, and other medical services. Both Medicaid and Medi-Cal are state and federal programs, respectively, that provide health coverage to low-income individuals and families. Medicaid is a joint federal and state program, while Medi-Cal is California’s Medicaid program. The enrollment process for Medicaid/Medi-Cal providers is managed by the individual state’s Medicaid agency, and it may differ from the Medicare enrollment process.

Providers can use the Provider Enrollment, Chain, and Ownership System, PECOS in short, to submit their Medicare enrollment applications online. PECOS streamlines the process and allows for electronic submission.

Enrolling a provider in Medicare can involve a detailed process, and healthcare professionals and facilities need to understand the requirements. The enrollment process is intended to ensure that healthcare providers meet certain standards and qualifications to participate in the program.


 Medicare Enrollment Process:

Step Enrolling a provider in Medicare or Medicaid is easy if you know about a few things and the process. Here’s a general overview of the process and some key information:

Determine Eligibility:

Healthcare providers need to determine their eligibility to participate in Medicare. Eligible providers may include physicians, nurse practitioners, hospitals, nursing homes, and other healthcare entities.

National Provider Identifier (NPI):

Before enrolling in Medicare, providers must obtain a National Provider Identifier (NPI). This unique identifier is used to identify healthcare providers and is required for billing purposes.

CMS-855 Forms:

The CMS-855 series consists of various forms used for different types of healthcare providers and suppliers. Each form corresponds to a specific category of provider or supplier. Some common CMS-855 forms include:

  • CMS-855A: Institutional providers (e.g., hospitals, skilled nursing facilities)
  • CMS-855B: Clinics, group practices, and certain other suppliers
  • CMS-855I: Individual practitioners (e.g., physicians, nurse practitioners)
  • CMS-855R: Reassignment of benefits

Complete the Appropriate CMS-855 Form

Providers must complete and submit the relevant CMS-855 form based on their provider type. The form collects information about the provider’s identity, qualifications, and compliance with Medicare rules.

Submit Supporting Documentation:

Along with the CMS-855 form, providers must submit supporting documentation, such as medical licenses, certifications, and other necessary credentials. This documentation helps verify the provider’s qualifications.

Credentialing and Verification:

Medicare contractors review the information provided, conduct credentialing, and verify the qualifications of the healthcare provider. This process ensures that providers meet the necessary standards to participate in the Medicare program.

Wait for Approval:

After submission, providers must wait for their applications to be processed and approved. The processing time can vary, but CMS aims to process applications within 60 days.


Providers are required to revalidate their Medicare enrollment information periodically to ensure ongoing compliance with program requirements.

Enrolling in Medicare or Medicaid/Medi-Cal can be challenging due to the complexity of the application process, the need for accurate documentation, and potential delays in processing. It’s crucial for providers to carefully follow the instructions provided by CMS or the state Medicaid agency, submit complete and accurate information, and stay informed about any updates or changes in the enrollment process.
