Health insurance is one of the most important tools for protecting your physical and financial well-being, but many people don’t fully understand what their plan actually covers. While terms like “deductible,” “copay,” and “premium” get thrown around often, the real question is: What services and treatments are included in your coverage—and which are not?
This article breaks down the core elements of a typical health insurance plan, what’s generally covered, what isn’t, and how to understand the fine print.
Why It’s Important to Know What’s Covered
Understanding your health insurance coverage helps you:
- Avoid surprise medical bills
- Get the most out of your benefits
- Make informed decisions about your care
- Plan for out-of-pocket expenses
Whether you have insurance through an employer, the Health Insurance Marketplace, or a private insurer, the structure of what’s covered is generally similar, especially under the Affordable Care Act (ACA).
Essential Health Benefits: What Most Plans Must Cover
Under the ACA, most health insurance plans are required to cover 10 essential health benefits. These benefits ensure comprehensive coverage for a wide range of health needs.
1. Ambulatory Patient Services (Outpatient Care)
Coverage includes doctor visits, same-day surgery, and care you receive without being admitted to a hospital.
2. Emergency Services
Visits to the emergency room are covered, and you can get emergency care even if the hospital is out-of-network.
3. Hospitalization
Covers surgeries, overnight hospital stays, and other in-patient treatments. You may still be responsible for coinsurance or deductibles.
4. Maternity and Newborn Care
Includes prenatal visits, labor and delivery, and care for newborns.
5. Mental Health and Substance Use Disorder Services
Covers therapy, counseling, inpatient treatment, and treatment for substance abuse. Mental health coverage is required to be equal to physical health coverage.
6. Prescription Drugs
Insurance must cover at least one drug in every category and class of approved medications. Exact coverage depends on your plan’s formulary (approved drug list).
7. Rehabilitative and Habilitative Services
Covers therapies to help you recover from injury, illness, or disability (rehabilitation), and to help you gain skills not previously acquired (habilitation).
8. Laboratory Services
Blood work, diagnostic tests (like X-rays or MRIs), and preventive screenings are generally covered.
9. Preventive and Wellness Services
Includes vaccinations, screenings (e.g., mammograms, cholesterol tests), and annual physicals—often at no cost to you if performed by in-network providers.
10. Pediatric Services
Covers children’s healthcare including dental and vision coverage for those under 18.
Common Services Typically Covered (But May Vary by Plan)
Doctor Visits
Most plans cover primary care and specialist visits. Copays or coinsurance usually apply, especially if the deductible hasn’t been met.
Preventive Care
Includes immunizations, routine screenings, and check-ups—often covered in full without requiring you to meet your deductible.
Diagnostic Imaging
X-rays, MRIs, CT scans, and other imaging tests are usually covered but may require preauthorization.
Surgery
Both outpatient and inpatient surgeries are typically included, though your out-of-pocket responsibility may vary.
Mental Health Services
Individual and group therapy, inpatient mental health care, and substance abuse treatment are covered, but provider networks can be more limited.
What’s Not Typically Covered (or Only Partially Covered)
While most plans offer robust coverage, some services are excluded or only partially covered. Always check your Summary of Benefits and Coverage (SBC) or Evidence of Coverage (EOC) for details.
Cosmetic Procedures
Elective procedures like plastic surgery for aesthetic reasons are generally not covered.
Dental and Vision (for Adults)
Most health insurance plans do not cover routine dental or vision care for adults. Separate dental and vision plans are usually required.
Fertility Treatments
Coverage for treatments like IVF varies widely and is often limited or excluded entirely.
Long-Term Care
Assistance with daily living (e.g., in a nursing home or assisted living) is typically not covered. Long-term care insurance is a separate product.
Alternative Therapies
Acupuncture, chiropractic care, massage therapy, and naturopathy may not be covered unless required by your state or explicitly included in your plan.
Travel Vaccines
Vaccines required for international travel are often excluded or only partially covered.
In-Network vs. Out-of-Network Coverage
What’s the Difference?
- In-network providers have contracts with your insurance company and offer discounted rates.
- Out-of-network providers do not, meaning your costs are much higher—or not covered at all.
Why It Matters
Using in-network doctors and facilities helps you avoid balance billing and reduces your overall costs. Some plans like HMOs won’t pay anything for out-of-network care except in emergencies.
Understanding Your Plan’s Structure
HMO (Health Maintenance Organization)
- Requires you to use in-network providers
- Requires referrals for specialists
- Lower premiums and out-of-pocket costs
PPO (Preferred Provider Organization)
- Offers more flexibility with provider choice
- Doesn’t require referrals
- Higher premiums but includes out-of-network coverage
EPO (Exclusive Provider Organization)
- Only covers in-network care (like an HMO)
- Doesn’t require referrals (like a PPO)

This document explains your plan’s covered services, copays, and deductibles.
Step 2: Use Online Tools
Many insurers provide online portals or apps where you can:
- View covered services
- Search for in-network providers
- Track deductibles and out-of-pocket maximums
Step 3: Call Customer Service
If you’re ever unsure whether a service or treatment is covered, contact your insurance provider before scheduling care.
What to Do If a Service Isn’t Covered
- File an appeal: If a claim is denied, you have the right to appeal the decision.
- Ask for a preauthorization: Some services require prior approval to be covered.
- Negotiate a cash price: If uninsured for a service, some providers may offer lower cash-payment rates.
- Use a Health Savings Account (HSA) or Flexible Spending Account (FSA): These accounts let you pay for out-of-pocket expenses tax-free.
Conclusion
Health insurance is more than just a safety net—it’s a crucial part of your overall well-being and financial planning. But understanding exactly what your plan covers—and what it doesn’t—can save you from unexpected bills and frustration.
Be proactive:
- Review your benefits annually
- Stay in-network
- Use preventive care
- Ask questions when in doubt
The more informed you are, the better you’ll be at using your insurance wisely and protecting both your health and your wallet.
