The treatment guidelines are written from a clinical perspective, to guide clinical care. Providers should consult the Medical Aid Rules and Fee Schedule (MARFS) for documentation and coding requirements.
The Treatment Guidelines (also called Medical Treatment Guidelines, Medical Practice Guidelines or Review Criteria) are evidence based and were developed by the Office of the Medical Director in collaboration with practicing physicians and advisors.
Some guidelines are intended to be educational tools for medical providers. Some guidelines and the review criteria are used by L&I in the Utilization Review program and claim management process to promote best practices and improve the health of injured workers. They are published by L&I, which is solely responsible for coverage decisions that may result from their use.
See Conditions and Treatments (Coverage Decisions) for additional information.
How to use the guidelines
Health care providers are expected to be familiar with the guidelines and follow the recommendations. Good medical judgment is important in deciding how to use and interpret this information.

Advanced Imaging Guidelines
The Washington Legislature passed a new law in 2009 (ESHB 2105/ Chapter 258, Laws of 2009) that directed the State to convene an Advanced Imaging Management Work Group. The Work Group was directed to identify evidence-based best practice guidelines for advanced imaging; State agencies were directed to implement the Work Group recommendations. Work Group recommendations include:
- Evidence-based checklists for certain high-cost, high-use imaging studies.
- Web-based utilization review.
For information about how to request authorization please see L&I's utilization review information pages.
