Provides that within funds appropriated for this purpose, and with the goal of catalyzing and providing financial incentives for the rapid expansion of primary care practices that use the medical home model, the department of health shall offer primary care practices an opportunity to participate in a medical home collaborative program.

Requires the collaborative program to be structured to promote adoption of medical homes in a variety of primary care practice settings throughout the state and consider different populations, geographic locations, including at least one location that would agree to operate extended hours, which could include nights or weekends, and other factors to allow a broad application of medical home adoption, including rural communities and areas that are medically underserved.

Declares that as part of a required five-year plan to change reimbursement the health care authority and department of social and health services must expand their assessment on changing reimbursement for primary care to support adoption of medical homes to include medicare, other federal and state payors, and third-party payors, including health carriers under Title 48 RCW and other self-funded payors.
