a) In any action for damages arising out of the professional negligence of a health care provider, no claim for punitive damages shall be included in a complaint or other pleading unless the court enters an order allowing an amended pleading that includes a claim for punitive damages to be filed.

Section of the Civil Code. The court shall not grant a motion allowing the filing of an amended pleading that includes a claim for punitive damages if the motion for such an order is not filed within two years after the complaint or initial pleading is filed or not less than nine months before the date the matter is first set for trial, whichever is earlier.
