Cal. Ins. Code § 10177.5

A self-insured employee welfare benefit plan which is written or issued for delivery outside California in a state the laws of which require recognition of psychologists licensed in such state for services performed within the scope of psychological practice shall not be deemed to prohibit the insured from selecting a psychologist licensed in California to perform services in California which are covered under the terms of the policy even though such psychologist is not licensed in the state in which the insurance is written or issued for delivery.
