  • Mental health services

Coverage Levels Vary

  • Prior authorization status
  • Medical necessity determination

Reading Benefit Descriptions

For each covered service, you'll typically find:

  • What's covered
  • Any requirements (prior auth, referral)
  • Cost-sharing (copay, coinsurance)
  • Limitations (number of visits, dollar caps)

Understanding Exclusions

What Are Exclusions?

Exclusions are services your plan does not cover at all. Common exclusions include:

  • Cosmetic procedures
  • Experimental treatments
  • Non-emergency care abroad
  • Services not medically necessary
  • Certain dental and vision services

Where to Find Exclusions

Look in:

  • "What's Not Covered" section of SBC
  • "Exclusions and Limitations" in EOC
  • Appendices listing excluded services

Examples of Exclusions

Exclusion What It Means
Cosmetic surgery Procedures for appearance only
Custodial care Long-term help with daily activities
Experimental Treatments not proven effective
Infertility (some plans) Fertility treatments
Weight loss surgery (some plans) Bariatric procedures

Important Definitions

Key Terms

Your policy defines important terms specifically:

Medically Necessary: Services that are appropriate and required to treat a condition. Insurance defines this, not just your doctor.

Covered Service: A service your plan pays for, subject to terms and conditions.

Allowed Amount: What your plan considers reasonable for a service (also called eligible, negotiated, or contracted amount).

Out-of-Pocket Maximum: The most you'll pay in a plan year before insurance covers 100%.

Why Definitions Matter

The policy's definition controls:

  • Understanding your plan's specific meaning
  • May differ from common understanding
  • Affects whether claims are paid
