What is an NPI number?
The purpose of NPI is to accurately identify organizations and health care providers across various administrative healthcare transactions, including billing, credentialing, and patient referrals.
Obtaining an NPI is legally required for most healthcare providers, including occupational, physical, speech, and mental health therapists. An NPI is essential for therapists to have in order to bill insurance companies and receive reimbursement for services.
An NPI establishes a professional identity, facilitates network participation with insurance providers, and allows for referrals for individual therapists and therapy organizations. Follow along as we delve into how to obtain an NPI, the NPI lookup tool, common issues, and best practices.

How to obtain an NPI
Healthcare providers such as therapists must apply for an NPI through the National Plan and Provider Enumeration System (NPPES). Providers can follow these general steps:
- Gather the required information, such as:
- Legal name
- Tax ID number
- Professional Licenses
- Address
- Type of healthcare provider
- Complete the NPI application
- This can be completed online, through mail, or by a designated enrollment intermediary.
- Information must be accurate and complete.
- Submit the completed application to NPPES
- Wait for processing
- It can take several weeks for NPPES to process your application.
There are two different types of NPIs. Here are the key differences:
NPI Type 1: Individual NPI. This is assigned to individual healthcare providers, such as independent contractors or solo practitioners. Therapists who practice under their own name or who work alone, are required to have an individual NPI.
NPI Type 2: Organizational NPI. Organizations that bill for healthcare services, such as private practices, clinics, or healthcare systems are assigned an organizational NPI. If you work in one of these settings, the organization has an NPI. You may also need an individual NPI if you provide services independently.

Benefits of NPI lookup for therapists
Using the NPI lookup tool offers several benefits for therapists:
Ensure accurate credentialing: By regularly using NPI Lookup, you can ensure that your information is accurate and up-to-date. Outdated information or errors in your NPI record can result in delayed payments, referrals, and insurance network participation.
Facilitate patient referrals and collaboration: Using the NPI Lookup tool allows providers to accurately refer patients or identify potential collaborators, while ensuring the provider is credentialed.
Ensures accurate billing/reimbursement: Verifying that the information on the NPI Lookup tool matches what insurance payers have listed can ensure accurate billing and reimbursement of services.
NPI lookup and insurance billing
Insurance providers rely on NPI numbers to process claims and reimbursements. Using NPI Lookup ensures that a provider’s billing information matches the information in the insurance company’s database. This can prevent claim denials and delays in payments, which can result from a provider having missing or inaccurate identifying information.
Providers can use the NPI Lookup tool to ensure overall consistency with insurance and Medicare/Medicaid provider databases.

Common issues with NPIs
It’s important to be aware of some common issues related to NPIs. Incorrect or incomplete NPI data can lead to delays in payments, denials for reimbursement, and other administrative issues.
Be sure to double-check your information to ensure it is accurate. You can fix errors in your NPI information by visiting the NPPES website where you can create a new account if needed or sign in, and manage your information.
An NPI can become inactive for several reasons, such as a failure to periodically update or confirm information, discontinuation of a practice, change in practice status, or non-use for a long period of time.
To reactivate an NIP, the healthcare provider needs to login to NPPES and update information. The provider may also need to re-enroll as a provider with Medicare or Medicaid and correct any disciplinary or licensing issues.
Best practices for managing NPI information
Providers should regularly verify and update their NPI information to maintain accurate records and ensure compliance with healthcare regulations.
Therapists should check and update their NPI information annually or whenever they have a change in key details, such as name, specialty, contact information, or practice location.
Maintaining consistency between NPI data and other professional licensure or organizational records is important to avoid discrepancies that could affect credentialing, insurance claims, or billing.
Providers can leverage the NPI Lookup tool for professional development. Researching competitors and colleagues within your field and area of specialty can provide you with valuable insights into best practices, trends, and networking opportunities.
NPI Lookup can also allow you to remain informed about industry standards and ensure that your practice aligns with current best practices in your specialty. This can enhance your professional reputation and facilitate informed decisions for your career.
The NPI Lookup tool is a valuable resource for therapists. It allows them to verify their credentials, ensure accurate billing, and facilitate collaboration among other healthcare professionals.
Consistently checking and maintaining your NPI information can help you avoid costly errors such as denials and delays in insurance reimbursement. It can also help streamline patient referrals and ensure that you remain compliant with billing and legal requirements.
