An Act relative to determining capacity and invoking the health care proxy

This bill amends Massachusetts law (Chapter 201D) to update terminology related to healthcare decision-making. It replaces "attending physician" with "attending health care provider" throughout the law, explicitly including nurse practitioners and psychiatric nurse mental health clinical specialists as qualified decision-makers. This change directly affects patients who have designated a health care proxy, clarifying that their primary care provider (not limited to physicians) can legally act under the proxy. The key mechanism is a consistent terminology update across multiple sections of the law to reflect modern healthcare team structures.
