Tier 1

Tier 1 is the category of providers in a tiered insurance network for which an insurance plan requires the lowest member cost sharing compared with its other network tiers.

In plain English

In a tiered network, providers are grouped by what the member pays. Tier 1 names the group tied to the lowest share of costs under that plan. It is lower-cost for the member than the plan's other network tiers.

In context

Here, Tier 1 indicates that the provider is in the network tier with the plan's lowest member cost sharing.
