Cal. Ins. Code § 10711
No carrier shall be required by the provisions of this chapter:
(d) To offer coverage to, or accept applications from, a small employer for a benefits plan design within an area if the commissioner has found that the carrier will not have the capacity within the area in its network of providers to deliver service adequately to the eligible employees and dependents of that employee because of its obligations to existing group contractholders and enrollees and that the action is not unreasonable or clearly inconsistent with the intent of this chapter.
A carrier that cannot offer coverage to small employers in a specific service area because it is lacking sufficient capacity may not offer coverage in the applicable area to new employer groups with more than 50 eligible employees until the carrier notifies the commissioner that it has regained capacity to deliver services to small employers, and certifies to the commissioner that from the date of the notice it will enroll all small groups requesting coverage from the carrier until the carrier has met the requirements of subdivision (h) of Section 10705.
