OR HB4119

Managed care organizations (MCOs) certified for workers' compensation must not discriminate against any willing provider within their geographical service area who agrees to meet the MCO's rules, terms, and conditions for services

Expands the definition of "attending physician" for workers' compensation claims to include nurse practitioners, physician associates, chiropractic physicians, and naturopathic physicians without the previous time limitations (60 days/18 visits for chiropractors and naturopaths; 180 days for physician associates)

Removes restrictions that previously limited chiropractors, naturopaths, and physician associates to serving as attending physicians only for specified cumulative time periods from the first visit on an initial claim

Allows nurse practitioners and physician associates who are not MCO members to provide the same level of services as primary care physicians if they maintain the worker's medical records, have a documented treatment history, and agree to comply with MCO rules

Amends multiple Oregon Revised Statutes (ORS chapters 656, 657, and 659A) to update references and conform language throughout workers' compensation, employment, and reinstatement provisions to reflect the expanded attending physician definition
