HB 2041 passed the Legislature and is awaiting signature by the Governor. Once signed into law, the key provisions of the bill related to the collaborative model take effect January 1, 2025, with some minor changes taking effect July 1, 2026.

  • PA collaborative practice replaces the supervision model for experienced PAs with a collaboration model. In this model, PAs can interact with, consult with, or refer to a physician or other appropriate members of the health care team as indicated by the patient’s condition, the education, experience, and competencies of the physician assistant, and the standard of care.
  • The bill authorizes collaborative practice for PAs who have over 4,000 hours of post-graduate clinical experience and 2,000 hours of specialty experience. PAs are supervised until that point.
  • A PA’s scope of practice mirrors their participating physician’s or the group of physicians that the PA is working with in that specialty area(s) or department. PAs who have 10 years or 20,000 hours of specialty experience can work outside the scope of their participating physician(s) if they continue to obtain CME in that specialty and they are working in a medically underserved or rural area. This expanded scope must be described in a collaboration agreement.
  • PAs will enter into collaboration agreements, which can be signed by a participating physician or the PA employer (such as a medical director). The agreement is kept at the practice site and doesn’t need to be sent to the WA Medical Commission unless requested.
  • The bill removes the physician to PA ratio. Employers can staff their teams as they deem appropriate, and physicians can collaborate with as many PAs as they would like.
  • The bill authorizes direct pay for PA-provided care. This is especially helpful for PAs who don’t have an employment relationship with their participating physician or when a PA needs to reassign their payments. The bill does not affect PA reimbursement rates.
  • The bill makes PAs legally responsible for their medical decisions. The bill removed physician liability for care provided by PAs. This addresses one of the main reasons we hear physicians are not opting to hire and work with PAs.
