NPPES Registration FAQs

A National Provider Identifier (NPI) is a ten digit identification number, unique to each individual, that is issued to healthcare providers in the United States. The NPI is ten digits in length. The first nine digits are identifying digits, and the last is a “check digit.” The “check digit” assists in identifying invalid NPIs.  NPI numbers identify providers with payers throughout the healthcare industry and ensure payments are directed to the appropriate party. You can think of your individual NPI as an SSN for individuals.

NPIs are broken down into two categories:

  • Type 1 for individual providers
  • Type II for organizational NPIs

We cover them in more detail below and answer a number of frequently asked questions.

Npi registration

Npi registration type 1 overview

As stated above, individual healthcare providers will register under NPI Registration Type I. These include physicians, dentists, nurses, pharmacists, chiropractors, physical therapists, physician assistants, and sole proprietors.

A sole proprietorship is also considered Type I. A sole proprietorship may get only one NPI. They must report their social security numbers (not EINs). Virtually any healthcare provider could be a considered a sole proprietorship, including most of the examples listed in Type II.

Npi registration type 2 overview

Other types of healthcare providers will register under NPI Registration Type II. These include organizations that provide health care services or furnish supplies to patients; for example, hospitals, home health agencies, medical practices, HMOs, home health organizations, medical equipment suppliers, and pharmacies.

Solely owned companies that are healthcare providers get an NPI under Type II. The company needs to be registered in their respective state and obtain a tax id/EIN.  If the company is considered a “sub part”, a health care provider will provide the “Legal Business Name” (LBN) and Taxpayer Identification Number (TIN) of the “parent organization” healthcare provider.

How do i apply for an npi?

Obtaining your NPI number is the first step you must complete as a healthcare practitioner to obtain your billing privileges.  Oftentimes, providers will be issued NPI numbers while still in training. 

If you’re not sure if you have one, the first step would be to contact NPPES or view the NPI registry here.  You cannot begin any credentialing without first obtaining an NPI number.

In order to apply for an NPI, you first have an account with Identity and Access Management System (I&A).  One account will now give you the ability to manage PECOS, EHR Incentive Program and NPPES all with one login.  You can create your login for I&A here.

Once you have created your login, you will then have to walk through securing your account with MFA(multi-factor authentication) and then build your profile.  Once your profile has been created and approved, you will then have the ability to register for your NPI number.

Does my company need an NPI number?

Any company with a tax id number is required to have a type II NPI if they plan to bill insurance companies.  This includes medical supply companies, IPAs, pharmacies, hospitals, ASCs, medical practices and home health agencies.  Even if you are the only owner of the organization, you still must obtain a type II NPI.

Is my caqh id and NPI number the same?

No, your NPI number and CAQH number are different.  Your NPI number is issued by CMS and is a requirement for all healthcare providers that plan to bill insurance companies.  CAQH is a private organization that commercial payers utilize as a centralized credentialing database.  CAQH numbers are not needed for government payers.

Does my npi ever change?

No, your individual NPI will stay with you for as long as you are practicing. The information in your NPI profile can be changed but your actual NPI will remain the same. Your TYPE II NPI follows your entity so if you change your TAX ID, you will need a new organizational NPI.

DOes each location need an npi?

The short answer is Yes.  CMS is requiring healthcare organizations to link their locations to their entity and for billing purposes, they want each of your locations to have a unique TYPE II NPI.  This isn’t to say that it’s not possibly to credential a location using the primary business’s type II NPI but it does create challenges when it comes to linking payments to the correct location and could result in issues with Medicare in the event of an audit or when completing PECOS applications.  It is best to consult with an expert if you are unsure about how to update your credentialing profile.

Will my npi record be public?

After providing the NPIs to healthcare providers, the CMS publishes the parts of the NPI record that have public relevance, such as the provider’s name, specialty (taxonomy) and practice address.  This is why it is so critical to enter accurate and complete information.  Do NOT enter your cell phone number in the telephone section unless you want it shared all over the internet.

The following information will be made publicly available:

  • NPI number
  • Code
  • Name (Legal Business Name)
  • Provider Business Mailing Address First Line
  • Address
  • Telephone Number
  • Fax Number
  • Provider Business Practice Location Address
  • Authorized Official Title or Position: Name: Credential:
  • Telephone Number:
  • Provider Enumeration Date
