Health Insurance Terms
Understanding common insurance terms is essential for making informed health decisions. Below are some key terms you’re likely to encounter.
Adjusted Gross Income
A person’s total income for the year, minus certain adjustments.
Agents/Brokers/Enrollment Counselors
Trained professionals who can help assist consumers with their health insurance enrollment. There is no cost to use their services.
Allowed Amount
The maximum amount your health plan will pay for a covered healthcare service.
Balance Billing
When the cost for a healthcare service is greater than what is allowed by your plan, you may have to pay the difference.
For example, if the cost for a healthcare service is $100 and the allowed amount is $80, your provider may bill you for the remaining $20.
Binder Payment
The first initial payment to your health insurance carrier completes your enrollment. If you fail to pay your first month’s premium, your policy will not take effect and you will not be enrolled in coverage.
Co-insurance
The percentage you pay for covered health services after your deductible is met. Your health insurer or plan pays the rest of the allowed amount. Depending on your plan, your portion of the co-insurance could range from 20-40%.
Co-payment
The fixed amount you pay for a medical visit or medication, e.g., $15 per visit, is usually paid at the time you receive the service. This is considered part of your out-of-pocket costs, separate from premiums and deductibles. This may vary by the type of health care services being provided.
Deductible
The amount you must pay for health care services during a coverage year before your health insurance carrier starts covering costs. For example, if your plan has a deductible of $1,000, you will have to pay for any covered healthcare services that are subject to the deductible until you reach the $1,000 amount. After that, your plan will start covering costs according to your plan benefits. The deductible may not apply to all services.
Dependent
A person who is eligible for coverage under a policyholder’s health insurance plan. A dependent may be a spouse, domestic partner, or child. In some cases, you may also be able to cover a grandchild, an adult child with a disability, a foster child or someone for whom you are the legal guardian.
Emergency Medical Condition
An illness, injury, symptom (including severe pain), or condition severe enough that it requires immediate medical attention.
Emergency Medical Transportation
Ambulance services for an emergency medical condition. Your plan may include transportation by air, land, or sea.
Emergency Room Care/Emergency Services
Services provided to treat an emergency medical condition. Services may be provided in a licensed hospital’s emergency room or any location providing emergency medical services.
Excluded Services
Healthcare services that your plan does not cover or pay for.
Explanation of Benefits
A document that outlines the costs of a visit, what your health insurance policy covers, and how much you may owe. This is not a bill.
Habilitation Services
Healthcare services that help you keep, learn, or improve skills and functioning for daily living.
e.g., therapy for a child who isn’t walking or talking at the expected age or someone recovering from a stroke. May be inpatient or outpatient services.
Hospital Outpatient Care
Care in a hospital that does not require an overnight stay.
Hospitalization
Admission to a hospital as an inpatient that usually requires an overnight stay.
In-Network
Physicians, hospitals, or other healthcare providers your health insurer has contracted with to provide your health services. You may pay less when receiving in-network healthcare.
Medically Necessary
Healthcare services that are provided to a patient to prevent, evaluate, or diagnose an illness, injury, condition, disease, or its symptoms. Services deemed medically necessary must meet recognized standards of medicine.

The figure used to determine eligibility for premium tax credits and other savings for Marketplace health insurance plans.

Out-of-Network
Physicians, hospitals, or other healthcare providers your health insurer has not contracted with to provide your health services. Costs for out-of-network healthcare are typically higher.
Out-of-Pocket Costs
Medical Expenses that aren’t covered by your insurance plan. Out-of-pocket costs include deductibles, co-insurance, co-payments, and charges for services not covered.
Out-of-Pocket Maximum/Limit
The most you’ll pay for covered services within a coverage year. After you reach this max limit your health plan will pay for 100% of the costs.
Out-of-pocket limit does not include:
- Your monthly premium
- Out-of-network care and services
- Anything spent on services your plan doesn’t cover
- Costs above the allowed amount for a service that a provider may charge
Preauthorization
A health care service, treatment plan, prescription drug or use of medical equipment that must be approved as medically necessary by your health insurer. This may be required for certain services before you receive them. Preauthorization doesn’t guarantee your health insurance will cover the cost.
Pre-Existing Condition
Any health problem like asthma, diabetes, or cancer you had before the date new health coverage starts. You cannot be denied coverage through Your Health Idaho due to a pre-existing condition.
Preferred Provider
A physician or doctor who has a contract with your health insurance company to provide services at a discounted rate.
