A master contract refers to a broader agreement that outlines the terms of group insurance coverage and is not specific to the order of payments between plans. It simply serves as the overarching policy document rather than indicating which insurance plan pays first in the event of a claim.

A qualified plan typically meets specific regulatory requirements, such as those defined under the Affordable Care Act or other legal standards, but it does not inherently specify the order of payment in coordination of benefits. The term "qualified" addresses compliance rather than the functionality of payment order.

While a comprehensive major medical plan provides extensive medical coverage, it does not define the sequence of benefit payments. This type of plan focuses on the breadth of coverage offered rather than determining which plan is primary when multiple insurance policies are involved.
