Understanding Your Insurance Plan Documents

Your insurance plan documents contain the rules that govern your coverage. Understanding these documents is essential for identifying when your insurer is wrong — and building a stronger appeal.

Key Documents to Know

Summary of Benefits and Coverage (SBC)

A standardized, easy-to-read overview of your plan. Required by the ACA. Covers:
  • Deductibles, copays, coinsurance, out-of-pocket maximums
  • Covered services and exclusions
  • Cost examples for common medical situations

Summary Plan Description (SPD)

The detailed document governing employer-sponsored plans (ERISA). Includes:
  • Eligibility rules
  • Covered and excluded services
  • Claims and appeals procedures
  • ERISA rights statement

Evidence of Coverage (EOC) / Certificate of Insurance

The full contract for individual and marketplace plans. This is the authoritative document.

What to Look For When Appealing

  1. Covered services: Is the denied service listed as covered?
  2. Exclusions: Is there a specific exclusion? (Read carefully — vague exclusions can be challenged)
  3. Medical necessity definition: How does YOUR plan define it?
  4. Appeals process: Deadlines, where to send, what to include
  5. External review rights: Your right to independent review

Pro Tips

  • Request your full plan document in writing (insurers must provide it within 30 days under ERISA)
  • Highlight the specific plan language that supports your appeal
  • If the plan language is ambiguous, courts generally interpret it in favor of the member
  • Compare the denial reason against the actual plan language — denials often overstate exclusions

Frequently Asked Questions

Where do I get my plan documents?

For employer plans, ask your HR department or call the number on your insurance card. For marketplace plans, log into your healthcare.gov account or contact your insurer. Under ERISA, your employer must provide plan documents within 30 days of your written request.

What if the plan document contradicts what my insurer told me?

The official plan document (SPD or EOC) governs. If a customer service rep told you something was covered but the plan document excludes it, the document typically controls. However, some states enforce verbal representations through estoppel doctrines.
