Electronic Funds Transfer (EFT)/Direct Deposit Alert 

L&I account information moving to ProviderOne doesn’t include electronic payment information. You’ll need to sign in to ProviderOne and add your bank account details to continue or start EFT/Direct Deposit after your account moves. You may need to make additional changes (e.g. update location, ownership) to submit the modification.

If you don’t add your EFT/Direct Deposit information, L&I payments will be sent by mail to the billing address we have on file.

    NPI Requirement

    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

  • 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.
