H.903 is a bill that aims to enhance the process of involuntary treatment for individuals in need of mental health care. It authorizes licensed physicians and psychiatrists to consider a broader range of behavioral information when determining if a prospective patient meets the criteria for treatment. This includes relevant information from caregivers, family members, friends, school employees, workplace colleagues, treating providers, law enforcement, and other first responders, particularly data from the days and weeks leading up to the examination.

Additionally, the bill stipulates that physicians and psychiatrists should not rely solely on the patient's presentation during the examination or certification process. Instead, they are required to take into account ongoing risks that may not be evident in a clinical setting, and any such information must be documented in the patient's medical record. This approach aims to provide a more comprehensive understanding of the patient's situation and needs, ultimately improving the quality of care and decision-making in mental health treatment.
