Ins. Code, § 10120.3

(a) With respect to a contract between an insurer covering dental services and a dentist to provide covered dental services to insureds, the contract shall not require a dentist to accept an amount set by the insurer as payment for dental care services provided to an insured that are not covered services under the insured’s policy. This subdivision shall only apply to provider contracts issued, amended, or renewed on or after January 1, 2011.

(b) A provider shall not charge more for dental services that are not covered services under a health insurance policy than his or her usual and customary rate for those services. The department shall not be required to enforce this subdivision.

(c) The evidence of coverage and disclosure form, or combined evidence of coverage and disclosure form, for every health insurance policy covering dental services, or specialized health insurance policy covering dental services, that is issued, amended, or renewed on or after July 1, 2011, shall include the following statement:

IMPORTANT: If you opt to receive dental services that are not covered services under this policy, a participating dental provider may charge you his or her usual and customary rate for those services. Prior to providing a patient with dental services that are not a covered benefit, the dentist should provide to the patient a treatment plan that includes each anticipated service to be provided and the estimated cost of each service. If you would like more information about dental coverage options, you may call member services at [insert appropriate telephone number] or your insurance broker. To fully understand your coverage, you may wish to carefully review this evidence of coverage document.

(d) For purposes of this section, “covered services” or “covered dental services” means dental care services for which the insurer is obligated to pay pursuant to an insured’s policy, or for which the insurer would be obligated to pay pursuant to an insured’s policy but for the application of contractual limitations such as deductibles, copayments, coinsurance, waiting periods, annual or lifetime maximums, frequency limitations, or alternative benefit payments.
