Health Insurance Terms That Actually Decide What You Pay

Most people choose a health plan on the monthly premium. The premium is often the smallest factor in what a year of care actually costs.

Deductible

The amount you pay yourself before the plan starts contributing. A plan with a low premium and a high deductible can cost far more over a year with any significant treatment. Some services — routine check-ups, certain screenings — are often covered before the deductible is met, which is worth checking.

Copay and coinsurance

A copay is a fixed amount per visit or prescription. Coinsurance is a percentage of the cost after the deductible is met. Coinsurance is the riskier of the two, because a percentage of a large hospital bill is itself a large number.

Out-of-pocket maximum

This is the most important figure in the document and the one least often read. It caps what you can pay in a policy year for covered, in-network care. Above it the plan pays everything covered.

When comparing plans, the honest comparison is: premium for the year, plus the out-of-pocket maximum. That is your worst-case cost, and it frequently ranks plans differently from premium alone.

Network

The list of providers who have agreed rates with your insurer. Going outside it can mean paying far more or everything. Networks change during the policy year, so a doctor who was in-network last year may not be now.

The recurring trap is a hospital that is in-network while an individual practitioner working inside it is not. Ask about every provider involved, not just the hospital.

What to check before you need it

Whether your regular medications are on the plan’s formulary and at what tier. Whether specialist visits need a referral. What prior authorisation is required for planned procedures. And whether your existing doctors are in-network for the coming year, not the last one.
