Update licensing requirements for facilities licensed by the department of public health and human services

This bill updates licensing requirements for facilities regulated by Montana's Department of Public Health and Human Services, including community homes for people with severe or developmental disabilities. It adds a specific definition for "substance use disorder treatment facility" and amends multiple state codes to clarify what constitutes a health care facility and provider. The legislation also revises definitions related to managed care plans, emergency medical conditions, and health benefit plans to ensure consistency across health-related statutes. These changes aim to modernize the legal framework governing health care facilities without altering existing operational requirements.
