Subchapter V - COORDINATION OF BENEFITS
Section 3.3508 - Procedure to be Followed by Secondary Plan

In determining the amount to be paid by the secondary plan on a claim, should the plan wish to coordinate benefits, the secondary plan must calculate the benefits it would have paid on the claim in the absence of other health care coverage and apply that calculated amount to any allowable expense under its plan that is unpaid by the primary plan. The secondary plan may reduce its payment by the amount that, when combined with the amount paid by the primary plan, results in the total benefits paid or provided by all plans for the claim equaling 100 percent of the total allowable expense for that claim. In addition, the secondary plan must credit to its plan deductible any amounts it would have credited to its deductible in the absence of other health care coverage.
