An error is material and egregious if the error is clear to the director based on information the director finds to be reliable and results in an increase or decrease to a hospital's supplemental payment amounts under this article, or in a hospital's quality assurance fee payments, of at least one million dollars ($1,000,000) for any subject fiscal year. The director's determination whether to exercise his or her discretion under this section and any determination made by the director under this section shall not be subject to judicial review, except that a hospital may bring a writ of mandate under Section 1085 of the Code of Civil Procedure to rectify an abuse of discretion by the department in correcting that hospital's data when that correction results in greater fees for that hospital pursuant to Sections 14169.52 and 14169.53 or lower supplemental payments for that hospital pursuant to Section 14169.54 and 14169.55.
