Join the Medical Provider Network

Beginning January 1, 2013, all current and new providers in Washington State of the following types must be in our network to provide care for injured workers (including those employed by self-insured businesses) beyond the initial office or emergency-room visit:

  • Physicians (Some hospital-based physicians don't need to enroll - see details)
  • Chiropractors
  • Naturopathic Physicians
  • Podiatric Physicians & Surgeons
  • Advanced Registered Nurse Practitioners
  • Physician Assistants
  • Dentists
  • Optometrists

— Why you should apply to join the network.


If you are not one of these provider types, or you do not practice in Washington State, do not submit a network application.  This includes massage therapists, physical therapists, occupational therapists, speech therapists, psychologists, and all other provider types not listed above.  You can continue to treat injured workers without joining the network, but you must have an L&I provider number.

What if I don't join the network?

Beginning January 1, 2013, L&I will pay non-network providers only for an initial office or emergency room visit. Beginning Fall 2012, we will tell you more about how to help your patients transition care, should you choose not to enroll in the network.
