What Is a Medicare Plan Evidence of Coverage?

Short answer

The Evidence of Coverage is the detailed annual document describing a Medicare Advantage or Part D plan’s benefits, costs, rights and operating rules for a specific plan year.

Coverage And Action

Use the current EOC to examine cost sharing, network requirements, authorization, drug procedures, exclusions, grievances and appeals.

Not Automatic

An EOC from a prior year should not be used to establish current benefits, networks, cost sharing or utilization rules.

Practical Example

A Summary of Benefits may list a service copay, while the EOC explains the conditions, authorization rules and limitations that apply.

Questions to verify

  • Is this the current plan-year EOC?
  • What conditions apply to the benefit?
  • Does another plan document control providers or drugs?
