The Montana Volunteer Health Care Services Act aims to enhance access to health care services for residents, particularly in remote and underserved areas. The bill allows health care providers licensed in any state, as well as retired health care providers, to voluntarily provide health care services in Montana without the need for additional licensure. It establishes definitions for terms such as "free clinic," "health care provider," and "sponsoring organization," and outlines the requirements for these organizations to register with the Department of Public Health and Human Services. Additionally, the bill mandates that sponsoring organizations maintain records of services provided and submit annual reports.

The legislation also provides legal immunity for health care providers who offer voluntary services, protecting them from civil liability except in cases of gross negligence or willful misconduct. It specifies that patients must be informed that providers may not be held liable for ordinary negligence if they lack malpractice insurance. The bill includes provisions for the registration of sponsoring organizations, the maintenance of service records, and the conditions under which health care providers can operate without fear of legal repercussions, thereby encouraging more professionals to participate in volunteer health care efforts.
