AZ HB2365

Establishes that American College of Occupational and Environmental Medicine (ACOEM) occupational medicine practice guidelines are presumptively correct on the extent and scope of medical treatment in workers' compensation cases.

Allows the presumption in favor of ACOEM guidelines to be rebutted by preponderance of evidence showing a variance is both necessary to provide required treatment and consistent with other nationally recognized evidence-based medical guidelines.

Requires treatment for injuries not covered by ACOEM guidelines to follow other nationally recognized evidence-based medical treatment guidelines that are scientifically based and generally recognized by the national medical community.

Requires physicians disagreeing with treatment modification or denial under ACOEM guidelines to support alternative treatment requests with specific references and excerpts from other nationally recognized evidence-based medical treatment guidelines.

Provides definitions for "evidence based," "medical treatment guidelines," "nationally recognized evidence based medical treatment guidelines," and "peer reviewed" for purposes of implementing these treatment standards.
