Deductible, Copay, Coinsurance, Out-of-Pocket Max: How the Terms Interact

Four numbers govern what a US health plan costs you, and they apply in sequence.

US health plans use four cost terms that most people can define individually and few can describe working together. They apply in order across a plan year, and understanding the sequence is what lets you compare two plans properly.

The four numbers

Premium. What you pay each month to hold the plan. It does not count toward anything else on this list.

Deductible. What you pay for covered services before the plan starts paying its share. Resets every plan year.

Copay. A fixed amount for a specific service, such as $30 for a primary care visit. Some copays apply before you meet the deductible.

Coinsurance. Your percentage share after the deductible. With 20% coinsurance, the plan pays 80% and you pay 20%.

Out-of-pocket maximum. The ceiling. Once your deductible, copays and coinsurance add up to this figure, the plan covers 100% of covered in-network care for the rest of the year. Premiums do not count toward it.

The sequence

Take a plan with a $2,000 deductible, 20% coinsurance and a $7,000 out-of-pocket maximum, and a year with $30,000 of covered in-network care.

You paid $7,000 plus twelve months of premiums. The out-of-pocket maximum stopped the coinsurance from running further.

Network is the term that costs people most

Everything above assumes in-network care. Out-of-network treatment can carry a separate and higher deductible, a separate out-of-pocket maximum, or no coverage at all depending on plan type.

Federal protections now limit surprise billing for emergency care and for out-of-network providers working at in-network facilities. Outside those protections, confirming that a provider is in network before scheduling is the single most valuable thing you can do with a health plan.

Check the facility and the individual provider separately. A hospital being in network does not guarantee that the anesthesiologist or the radiologist reading your scan is.

Plan types in one line each

• HMO. Care coordinated through a primary care physician, referrals usually required, little or no out-of-network coverage. Lower premiums.
• PPO. No referral needed, some out-of-network coverage. Higher premiums.
• EPO. No referrals, but no out-of-network coverage outside emergencies.
• HDHP. A high-deductible plan, lower premium, and eligible to pair with a health savings account.

Comparing two plans

Premium alone answers nothing. Estimate two scenarios instead.

A low-use year: twelve months of premiums plus a few copays. A high-use year: twelve months of premiums plus the full out-of-pocket maximum. Run both numbers for each plan you are considering.

A high-deductible plan usually wins the low-use scenario. A lower-deductible plan often wins the high-use one. Which matters more depends on your circumstances and on whether you could absorb the worst case if it arrived.

Check the prescription formulary too, since a plan that looks cheaper can price a medication you take in a tier that erases the difference.

Health savings accounts

Pairing an HSA with an eligible high-deductible plan gives you an account with a tax advantage on the way in, on growth, and on qualified withdrawals. Contribution limits are set annually. Unused balances carry forward rather than expiring, and the account stays yours if you change employer.

That differs from a flexible spending account, where funds typically must be used within the plan year subject to limited carryover or grace period rules.
