Doctors would not be required to give patients as much information about alternative treatments available to them under a Republican-sponsored bill up for a committee vote.
The Assembly Judiciary Committee is scheduled to vote on the measure Thursday.
The proposal is backed by many in the medical community despite concerns from some that patients won't get helpful information.
The bill is a reaction to a 2012 Wisconsin Supreme Court ruling that said a doctor's "informed consent" duty includes telling a patient about medical tests and treatments that may be appropriate for a patient's symptoms, even if the doctor doesn't believe the patient has the underlying condition or disease.
The measure would change the law from a "reasonable patient standard" to a "reasonable physician standard."
