    Healthcare providers need an NPI for L&I's transition to ProviderOne.

    L&I is transitioning to ProviderOne, a new enrollment and credentialing system. To prepare for the transition, all healthcare providers who are HIPAA-covered entities (individuals or organizations) must obtain a National Provider Identifier (NPI).

    HIPAA-covered entity health care providers include:

    Individual (Entity Type 1) Organizations (Entity Type 2) 
    • Chiropractors
    • Dentists
    • Nurses
    • Physical, Occupational & Massage Therapist
    • Physicians
    • Nurse Case Managers
    • Psychologists
    • Ambulance Companies
    • Clinics
    • Group Practices
    • Home Health Agencies
    • Hospitals
    • Laboratories
    • Nursing Homes
    • Pharmacies
    • Suppliers of Durable Medical Equipment (DME) ​

    What happens if I don't obtain an NPI number?

    Here’s some important items for you to know, if you do not obtain an NPI number.

    • We cannot migrate your provider account information to ProviderOne without an NPI number. We ask that you apply for your NPI number and inform us of it.
    • If you currently receive EFT (Direct Deposit) payments from us, once migration has occurred, you will receive paper warrants/checks in the mail.
    • You will not be able to make any changes/updates to your provider account after migration, if you do not obtain an NPI number prior to this transition (individual providers or organizations).
    • We will no longer accept paper applications or change forms.

    Apply today for an NPI number!

    Visit the National Plan & Provider Enumeration System (NPPES) to apply for a new individual or organization NPI number: nppes.cms.hhs.gov/#/. See step-by-step application instructions in the resources section below.

    Once you obtain your NPI number, you will need to register it with L&I. You may email the following to: PACmail@Lni.wa.gov

    • Full Name (listed on your license)
    • Your L&I provider account number(s)
    • Your individual or organizational NPI issues by NPPES.
