Health-plan jargon hides the four numbers that actually determine your bills. Learn these once and every plan becomes readable.
1. Premium — what you pay to have the plan
Your monthly bill, due whether or not you see a doctor. A subsidy can lower it. Everything below is what you pay on top of the premium when you use care.
2. Deductible — what you pay before the plan kicks in
The amount you pay yourself each year before most coverage starts. A $3,000 deductible means you cover the first $3,000 of covered care. Some services (like preventive visits and often generic drugs) are covered before you hit it.
3. Copay and coinsurance — your share after the deductible
- Copay: a flat fee for a service — say $30 for a doctor visit or $15 for a prescription.
- Coinsurance: a percentage — say 20% of the cost — that you pay after meeting the deductible. The plan pays the rest.
4. Out-of-pocket maximum — your safety net
The most you can pay in a year for covered, in-network care. Once you hit it — through deductible, copays, and coinsurance combined — the plan pays 100% of covered costs for the rest of the year. This is the single most important number for protecting you in a bad year, and it matters more than the premium alone.
A quick example
Say your plan has a $2,000 deductible, 20% coinsurance, and a $7,000 out-of-pocket max. You have surgery billed at $30,000. You pay the first $2,000 (deductible), then 20% of the rest until you reach the $7,000 cap — so your total for the year is $7,000, not $30,000. That cap is why insurance matters even with a high deductible.
