Ins. Code, § 10120.2

(a) This section shall only apply to a disability insurer that issues a dental insurance policy pursuant to this part.

(b) For purposes of this section, the following terms have the following meanings:

(1) “Coordination of benefits” means the method by which a disability insurer and one or more other disability insurers, health care service plans covering dental services, or specialized health care service plans, covering dental services, pay their respective reimbursements for dental benefits when an insured is covered by multiple disability insurers, or a combination of disability insurers and health care service plans or specialized health care service plans.

(2) “Primary dental benefit plan” means a dental insurance policy issued by a disability insurer regulated pursuant to this part or a health care service plan or specialized health care service plan contract regulated pursuant to Chapter 2.2 (commencing with Section 1340) of Division 2 of the Health and Safety Code that provides an insured or enrollee with primary dental coverage.

(3) “Secondary dental benefit plan” means a dental insurance policy issued by a disability insurer regulated pursuant to this part or a health care service plan or specialized health care service plan contract regulated pursuant to Chapter 2.2 (commencing with Section 1340) of Division 2 of the Health and Safety Code that provides an insured or enrollee with secondary dental coverage.

(c) A disability insurer that issues a dental insurance policy shall declare its coordination of benefits policy prominently in its evidence of coverage or insurance policy with both insured and policyholder.

(d) When a primary dental benefit plan is coordinating its benefits with one or more secondary dental benefit plans, it shall pay the maximum amount required by its policy with the insured or policyholder.

(e) A disability insurer that issues a dental insurance policy, when acting as a secondary dental benefit plan or insurer, shall pay the lesser of either the amount it would have paid in the absence of any other dental benefit coverage, or the insured’s total out-of-pocket cost payable under the primary dental benefit plan for benefits covered under the secondary plan or policy.

(f) Nothing in this section is intended to conflict with or modify the way in which a disability insurer that issues a dental insurance policy determines which dental benefit plan is primary and which is secondary in coordinating benefits with another insurer or plan pursuant to existing state law or regulation.
