Health Insurance FAQs 2025: How It Works & Smart Ways to Save

Health-insurance cheat sheet 2025: how it works, why it’s pricey, what’s tax-deductible, and open-enrollment dates – FeeSlayer’s guide to smarter coverage.

1. How does health insurance work?

Think of insurance as a giant group chat where everyone chips in a little so no one gets stuck with a five-figure hospital bill. You pay:

• Premium – your monthly “subscription.”
  Example: You pay $200/month to stay insured, even if you never visit a doctor that month.
  

• Deductible – the amount you cover before the insurer truly kicks in.
  This is the amount you must pay out of pocket each year before your insurance starts covering most services
  

• Copay/Coinsurance – your slice of each bill after the deductible.
  After your deductible is met, your insurer starts contributing — but you still pay part of the cost. A copay is a flat fee (like $30 for a doctor visit), while coinsurance is a percentage (like 20% of the bill).
  

• Out-of-Pocket Max – the ceiling that stops runaway costs.
  This is the highest total amount you'll pay for covered services in a calendar year, no matter how bad things get.
  Once you hit that max, the insurer pays 100 % of covered care for the rest of the year.

2. Why is health insurance so expensive?

• Rising hospital & drug prices
  The cost of medical procedures, hospital stays, and prescription medications keeps going up — especially in the U.S., where providers can charge significantly more than in other countries for the same services.

• Administrative overhead (hello, billing codes)
  The U.S. healthcare system is bloated with paperwork. Billing departments, claim disputes, insurance pre-authorizations — all this red tape means more staff and higher operating costs, which get passed on to you.

• An ageing, sicker population
  As the population gets older (and lives longer) and chronic diseases like diabetes and heart conditions become more common, people use more healthcare — and that drives up the average cost of covering everyone.

• Limited competition in many regions
  In some states, just one or two insurance companies dominate the market. With little competition, there's less pressure to offer affordable plans or negotiate lower rates with hospitals and doctors.

In short, the system rewards spending, not saving. That’s why FeeSlayer exists.

3. Are health-insurance premiums tax-deductible?

• Self-employed? Yes – you can deduct 100 % of premiums on Schedule 1, line 17 (see IRS Form 7206). (https://www.irs.gov/forms-pubs/about-form-7206) (IRS)
  

• W-2 employee? Premiums paid through payroll are usually pre-tax already, so no extra write-off.
  

• Marketplace plans paid with after-tax dollars may count as an itemized medical deduction, but only the portion above 7.5 % of adjusted gross income.

4. How do health-insurance deductibles work?

A deductible is basically a yearly cover-charge. Pay the first $X yourself; after that, cost-sharing begins. Choose a High-Deductible Health Plan (HDHP) only if you can also fund an HSA (triple tax-advantaged).

5. Can health insurance cover therapy, braces & more?

• Therapy: Thanks to the Mental Health Parity Act and ACA essential benefits, most plans must treat mental-health coverage like medical coverage – check network lists first. (https://www.hhs.gov/programs/health-insurance/mental-health-substance-use-insurance-help/) (HHS.gov)
  

• Braces: Often only for kids; adult orthodontics may need a top-tier dental add-on.
  

• Gym memberships: A few insurers (Oscar, Aetna “Attain”) reimburse fitness costs – small print applies.
  

6. Can health insurance be back-dated, denied, or cancelled?

• Back-dated: Only if you qualify for Medicaid retroactive eligibility or a newborn adoption scenario; private plans rarely allow it.
  

• Denied: Plans can rescind only for fraud or non-payment – not for getting sick (ACA rule).
  

• Cancelled: Missing premium payments triggers a grace period (usually 90 days with subsidies).

7. When is Open Enrollment 2025?

Federal Marketplace: Nov 1, 2024 – Jan 15, 2025. Pick a plan by Dec 15 for coverage starting Jan 1. (https://www.healthcare.gov/blog/open-enrollment-starts-soon-get-ready-now/) (HealthCare.gov)
State-run exchanges may shift by a week or two – always double-check. CMS overview: (https://www.cms.gov/newsroom/fact-sheets/marketplace-2025-open-enrollment-fact-sheet) (Centers for Medicare & Medicaid Services)

Missed it? A Special Enrollment Period opens after certain life events:

1. You lost your health coverage: laid off, quit a job, or aged out of your parent’s plan at 26.

2. You got married or divorced: marriage may allow you to join your spouse's plan. Divorce could mean you need a plan of your own.

3. You had a baby, adopted a child, or placed a child for adoption
   In these cases, coverage can even be backdated to the date of birth or adoption.

4. You moved: if you moved to a new ZIP code or county where your old plan isn’t offered, you’re eligible to switch.

5. You became a U.S. citizen or gained lawful immigration status: this opens up access to Marketplace plans and subsidies.

6. If you've been released from jail or prison, you now qualify to apply for coverage.

8. Health insurance for the self-employed

• Premium tax deduction (see § 3).
  

• Use the Marketplace to access income-based subsidies.
  

• Consider a Qualified Small Employer HRA if you hire staff – lets you reimburse their premiums tax-free.
