Cal. Gov. Code § 22855
The board shall withdraw its approval of a health benefit plan if it finds that the plan or carrier is not in compliance with the standards prescribed therefor, that the plan or carrier has not paid or will be unable to pay claims accrued or to accrue, or for other good cause as shown. The board shall provide reasonable notice of its intention to withdraw approval of a health benefit plan to any carrier, employee organization, or organization of physicians that may be directly interested, to the persons enrolled in the health benefit plan, and to other persons and organizations as the board may deem proper. The notice shall state the effective date of, and reason for, the withdrawal of board approval. The approval of a health benefit plan may not be withdrawn until after the notice and after all interested parties have been afforded reasonable opportunity for public hearing on the question. The hearings shall be conducted, insofar as practicable, pursuant to Chapter 5 (commencing with Section 11500) of Part 1 of Division 3.
