Twelve terms that decide what your employees pay
Nearly every benefits complaint traces back to one of the terms below. When employees understand them, they make better decisions and call you less often.
Deductible
The amount you pay for covered services before the plan starts paying its share. Most preventive care is covered before the deductible is met.
In plain English: The first chunk of a big bill is yours. After that, the plan steps in.
Coinsurance
After the deductible is met, coinsurance is the percentage of the cost you keep paying — commonly 20% — while the plan pays the rest.
In plain English: You and the plan split the bill by percentage, not by dollar.
Copay
A flat dollar amount for a specific service, such as $30 for an office visit. Copays often apply without needing to meet the deductible first.
In plain English: A fixed price at the door, no math required.
Out-of-Pocket Maximum
The most you will pay in a plan year for covered in-network services. Once you hit it, the plan pays 100% of covered care for the rest of the year.
In plain English: The ceiling. This is the number that protects a family in a bad year.
PPO vs. HMO
A PPO generally lets you see specialists without a referral and offers out-of-network coverage at a higher cost. An HMO typically requires a primary care referral and covers little or nothing out-of-network.
In plain English: PPO trades higher premium for freedom. HMO trades freedom for a lower premium.
Specialist Referral
A primary care provider's authorization to see a specialist. Required by most HMO and some tiered plans — and a common source of denied claims when skipped.
In plain English: On some plans, skipping the PCP step means the visit isn't covered.
Prior Authorization
The plan's advance approval for certain services, drugs, or imaging. Without it, an otherwise covered service can be denied.
In plain English: Permission slip. The provider usually handles it — but not always.
Prescription Formulary
The list of drugs a plan covers, sorted into tiers. Tier placement drives your cost, and formularies change — usually each January.
In plain English: Same drug, different tier, very different price. Check it every year.
Mail Order Pharmacy
A pharmacy benefit that ships maintenance medications, usually in 90-day supplies, often at a lower cost per day than retail.
In plain English: For pills you take every day, this is usually the cheaper route.
Telemedicine
A visit by video or phone with a licensed clinician. Widely covered, usually at a low or zero copay, and often available same-day.
In plain English: The fastest, cheapest first stop for a lot of common problems.
Preventive Care
Screenings, immunizations, and annual visits that ACA-compliant plans must cover at no cost-sharing when delivered in-network.
In plain English: Free when you use it right. It stops being free if it's coded as diagnostic.
Network Access
The set of providers who have contracted rates with your plan. Out-of-network care costs more — and in this region, network design determines whether Boston is affordable.
In plain English: The single most important thing to check before you switch carriers.
How the pieces fit
The order a claim actually moves through
Understanding the sequence removes most of the confusion:
- Is the provider in-network? If not, everything below changes and the out-of-pocket maximum may not protect the employee.
- Is it preventive or diagnostic? Preventive care is covered at no cost-sharing in-network. The same visit coded as diagnostic is not.
- Is there a copay? If yes, that is usually the whole story for that visit.
- Has the deductible been met? If not, the employee pays the allowed amount.
- Coinsurance applies. The employee pays their percentage of the allowed amount.
- Out-of-pocket maximum. Once reached, covered in-network care is paid at 100%.
"Allowed amount" is the contracted rate, not the billed charge — which is why an in-network provider almost always costs less even before the plan pays anything.
The most expensive misunderstanding
Employees assume the out-of-pocket maximum caps everything. On most plans it caps in-network covered spending only. Out-of-network balance billing can sit entirely outside it.
