What Are Exclusions?
Exclusions are services your health insurance plan explicitly will not pay for. If you receive an excluded service, you're responsible for the entire cost — it doesn't count toward your deductible or out-of-pocket maximum.
Common Exclusions on ACA-Compliant Plans
ACA plans (marketplace and private) must cover all essential health benefits, but may exclude:
- Cosmetic surgery (not medically necessary)
- Weight loss surgery (some plans cover, some don't)
- Fertility treatments (varies by state mandate)
- Adult dental and vision (not considered essential health benefits)
- Experimental or investigational treatments
- Long-term care / custodial care
Exclusions on Non-ACA Plans
Non-ACA plans (short-term, indemnity) can exclude far more. Common additional exclusions: pre-existing conditions, maternity care, mental health treatment, substance abuse treatment, preventive care, and prescription drugs. Always read the exclusions section before enrolling in a non-ACA plan.
Where to find exclusions: Every plan has a Summary of Benefits and Coverage (SBC) document that lists exclusions. Review this before enrolling — not after you get a bill for a service you assumed was covered.
