Please see "COB's Effect on Benefits" below in this section for details on primary and secondary plans. If you do not know which is your primary plan, you or your provider should contact any of the health plans to verify which plan is primary. The health plan you contact is responsible for working with the other plan(s) to determine which is primary and will let you know within 30 calendar days.
