Changes the 180-day deadline for serving expert affidavits in health care malpractice cases from "after commencement of the suit" to "after commencement of discovery under the Rules of Civil Procedure, rule 26.04(a)"

Makes the same 180-day deadline change for professional malpractice/negligence cases against non-health care professionals, aligning the timing to discovery commencement rather than action commencement

Allows parties or the court for good cause shown to agree to extensions of the time limits for serving expert affidavits in both health care and professional malpractice actions

Permits parties to call additional expert witnesses or substitute other expert witnesses without restriction beyond the initial 180-day deadline

Becomes effective the day following final enactment and applies only to causes of action commenced on or after the effective date
