What Is a Deductible?

What is a deductible?

A deductible is one way health insurance companies share the cost of medical care with the people they insure.

Think of it as your portion of covered healthcare costs before your insurance begins paying according to your plan's benefits.

For example, if your plan has a $2,000 deductible, you'll generally pay the first $2,000 in covered medical expenses yourself before your insurance starts paying its share for many covered services.

Not every healthcare service is subject to the deductible. Many health plans cover certain preventive services before you meet your deductible, and some services may require only a copayment or coinsurance depending on your plan.

How does a deductible work?

Although every health plan is different, the process generally works like this:

1. You receive covered medical care.
2. You pay the negotiated cost of covered services until you've met your deductible.
3. After your deductible is met, your insurance begins paying according to your plan's benefits.
4. You may still owe copayments or coinsurance until you reach your annual out-of-pocket maximum.

Most deductibles reset once each plan year.

What counts toward your deductible?

Expenses that commonly count toward a deductible include:

• Doctor and specialist visits
• Outpatient procedures
• Laboratory tests
• Diagnostic imaging, such as X-rays or MRIs
• Hospital care
• Emergency room services
• Certain prescription medications, depending on the plan

Monthly premiums generally do not count toward your deductible.

Because every health plan is different, review your plan documents to understand which services apply.

Deductible vs. copayment vs. coinsurance

These three terms are commonly confused.

Deductible

The amount you pay before many covered services begin sharing costs with your insurance plan.

Copayment (Copay)

A fixed dollar amount you pay for certain healthcare services, such as a primary care visit or prescription medication.

Coinsurance

A percentage of the cost you pay after you've met your deductible. For example, your plan may pay 80% of a covered service while you pay the remaining 20%.

Many health plans use all three cost-sharing methods.

Does every health insurance plan have a deductible?

No.

Some plans have no deductible, while others have separate deductibles for medical care, prescription drugs, or out-of-network services.

For example:

• Some employer-sponsored health plans have low deductibles.
• High Deductible Health Plans (HDHPs) have larger deductibles but may allow enrollment in a Health Savings Account (HSA).
• Medicare Part A and Part B each have their own cost-sharing rules that include deductibles established under federal law.

Always review your plan's Summary of Benefits and Coverage (SBC) to understand how your deductible works.

Why this matters

Understanding your deductible helps you estimate healthcare costs and avoid unexpected medical bills. Many people assume that having health insurance means every medical expense is immediately covered. In reality, your deductible often determines how much you'll pay before your insurance begins sharing the cost of care.
