MI HB5670

Amends MCL 600.2912a of the Revised Judicature Act of 1961 to revise medical malpractice standards and liability provisions.

Removes language restricting recovery for loss of opportunity to survive or achieve better results "unless the opportunity was greater than 50%" from malpractice claims.

Adds new subsection (3) creating a "professional judgment rule" that shields healthcare providers described in section 5838a(1) from liability if their conduct constituted exercise of professional judgment made with reasonable, good-faith belief that it was medically sound and in the patient's best interests.

Establishes that determining whether an act or omission constitutes professional judgment is a question of law for the court, while the standard of care question remains for the jury if professional judgment defense does not apply.

Prohibits the court's professional judgment ruling from being presented as evidence at trial and bars counsel from arguing professional judgment provisions to a jury.
