A bill in Albany would extend time given for patients to sue doctors for medical malpractice.
Patients now must file suits within two-and-a-half years after the alleged malpractice.
The bill would start the clock when a patient first realizes they were possibly misdiagnosed or harmed by a medical professional - as long as the lawsuit is filed within 10 years of the original incident.
Supporters say it can take patients several years to discover they received poor treatment.
New York's Medical Society opposes the change, saying it would raise malpractice insurance rates and cause "disastrous" increases in health care costs.
