House Bill 4078 of 2025 (Public Act 4 of 2026)

Summary

HB 4078 amends Michigan’s county medical examiner law to expand and clarify when a medical examiner or deputy medical examiner must investigate a death and when certain deaths must be reported. The bill requires investigation of deaths caused by violence, unexpected deaths, deaths without recent medical attendance, deaths occurring during home hospice care without recent physician or nurse attendance, and deaths resulting from abortion, whether self-induced or otherwise. It also requires examination of prisoners who die while incarcerated in county or city jails. The bill authorizes medical examiners to seek circuit court subpoenas for medical records and related materials during death investigations and makes those materials exempt from disclosure under the Freedom of Information Act. It also adds a process for referring unexpected or suspicious deaths of elderly or vulnerable adults to an elderly and vulnerable adult death review team, if one exists, and makes information obtained by that team confidential and FOIA-exempt. The act took immediate effect and is tied to the enactment of HB 4077.

Impact

HB 4078 amends sections 2 and 3 of 1953 PA 181, the state law governing coroner/medical examiner death investigations, by broadening reporting and investigative duties and by adding explicit subpoena authority and confidentiality protections. It affects physicians, hospital and institution staff, county medical examiners, deputy medical examiners, jails, and elder death review teams, while also creating FOIA exemptions for records gathered in these investigations. The bill also clarifies definitions for home hospice care, physician, and registered nurse, and it applies immediately upon enactment.

Sentiment

The bill appears to have broad bipartisan support and moved with little recorded opposition. Committee and floor votes were overwhelmingly favorable, including unanimous committee reports and large-margin passage in both chambers, with immediate-effect votes also passing comfortably. The lack of recorded committee discussion suggests the measure was treated as a technical or administrative update to death-investigation procedures rather than a highly contentious policy change.

Contention

The most notable substantive issue in the bill is its inclusion of deaths resulting from abortion, which may be viewed as politically sensitive even though the bill passed with strong support. Another point of interest is the expansion of confidentiality and FOIA exemptions for medical examiner records and elder review team information, which could raise transparency concerns for some stakeholders. The bill also creates a tie-bar to HB 4077, meaning its effectiveness depends on that companion bill becoming law, indicating the two measures were intended to operate together.
