Common Health Insurance Terms Explained
Health insurance terms can feel confusing fast. This glossary is designed to explain common medical benefits words and phrases in plain English, so employees and employers can better understand how coverage works.
These definitions are meant to be educational. Exact meanings, costs, and coverage rules can vary by insurance carrier and plan. If there is ever a difference between this glossary and an actual benefit plan, the official plan documents, Summary of Benefits and Coverage, certificate, or carrier materials will govern.
Please note: This glossary is for general educational purposes only and is not legal, tax, or coverage advice.
A
Aggregate Deductible
In a family plan, the full family deductible must be met before the plan begins paying for covered services for any family member, unless the plan uses an embedded deductible structure. This is different from an embedded deductible, where one person may begin receiving benefits sooner.
Allowed Amount
The maximum amount a health plan will pay for a covered service. You may also hear this called the eligible expense, negotiated rate, or payment allowance. If a provider charges more than the allowed amount and is out of network, the member may owe the difference.
Appeal
A request for a health plan or insurer to review a decision again, usually after a denial of a claim, service, or prescription.
Authorization / Prior Authorization
A requirement that a member or provider get approval from the health plan before certain services, procedures, or medications will be covered.
B
Balance Billing
When a provider bills a patient for the difference between the provider’s charge and the amount the plan allows. This is more commonly a concern without-of-network care.
Benefits
The health care services, treatments, supplies, or prescriptions a plan covers. Covered benefits vary by plan.
C
Calendar Year vs. Plan Year
A calendar year runs from January 1 through December 31. A plan year is the 12-month period your benefits plan uses, which may or may not match the calendar year. Deductibles, out-of-pocket maximums, and benefit resets often follow the plan year.
Carrier
Another word for the insurance company or health plan administrator providing the coverage.
Claim
A request for payment sent to the insurance company for services a member received. Claims may be submitted by the provider or, in some cases, by the member.
Coinsurance
The member’s share of the cost of a covered service, shown as a percentage. For example, if the plan pays 80% and the member pays 20%, that 20% is the coinsurance.
Coordination of Benefits (COB)
A process used when a person is covered by more than one health plan. Coordination of benefits determines which plan pays first and how the remaining balance may be handled.
COBRA
A federal law that can allow certain employees, retirees, spouses, former spouses, and dependent children to temporarily continue group health coverage after certain qualifying events cause coverage to end.
Copay / Copayment
A fixed dollar amount a member pays for a covered service, such as a doctor visit or prescription.
Cost Sharing
The portion of health care costs the member pays, usually through deductibles, copays, and coinsurance.
Covered Service
A medical service, treatment, item, or prescription the plan helps pay for according to the plan terms. Even covered services may still involve cost sharing.
D
Deductible
The amount a member pays for covered health care services before the plan starts paying. Some services, such as preventive care, may be covered before the deductible applies.
Dependent
A spouse, child, or other eligible individual who qualifies for coverage under someone else’s plan, subject to the plan’s rules.
E
EOB (Explanation of Benefits)
A statement from the health plan that explains how a claim was processed. It typically shows what the provider billed, what the plan allowed, what the plan paid, and what the member may owe. It is not usually a bill.
Embedded Deductible
In a family plan, an individual family member may begin receiving plan benefits once that person meets their own deductible, even if the full family deductible has not yet been met.
Emergency Medical Condition / Emergency Services
A serious condition requiring immediate medical attention to avoid serious harm. Plans generally define and cover emergency services differently than routine care.
Exclusions
Services, treatments, supplies, or situations a health plan does not cover. Even if a service is medically related, it may still be excluded under the plan.
Experimental or Investigational Services
Treatments, procedures, drugs, or devices a plan considers unproven, not widely accepted, or still under study for a specific condition. These services are often not covered unless the plan states otherwise.
F
Formulary
The list of prescription drugs covered by a health plan. Formularies may include tiers and may also require prior authorization or step therapy.
FSA (Flexible Spending Arrangement)
An employer-sponsored account that allows employees to be reimbursed for eligible medical expenses using pre-tax dollars, subject to IRS rules.
G
Generic Drug
A prescription drug that has the same active ingredient as a brand-name drug and is approved to work the same way. Generic drugs are often placed in a lower-cost tier than brand-name medications.
Grace Period
A period after a premium due date when coverage may remain in force if payment is made by the end of that window. Exact rules vary by policy and coverage type.
Grievance
A complaint made to a health plan about something other than a claim decision, such as service issues, access concerns, or administrative problems.
H
HDHP (High Deductible Health Plan)
A health plan design that has a higher deductible and meets IRS requirements for HSA eligibility.
HMO (Health Maintenance Organization)
A type of health plan that generally uses a defined provider network and often requires members to use in-network providers except in emergencies.
HRA (Health Reimbursement Arrangement)
An employer-funded arrangement that reimburses employees for qualified medical expenses, subject to plan and IRS rules.
HSA (Health Savings Account)
A tax-favored account that eligible individuals can use to pay or reimburse qualified medical expenses. To contribute, a person generally must be enrolled in an HSA-eligible HDHP and meet other IRS requirements.
I
In-Network
Doctors, hospitals, pharmacies, and other providers that have a contract with the health plan. Using in-network providers usually lowers the member’s cost.
M
Mail-Order Pharmacy
A pharmacy service that delivers prescription medications by mail, often for maintenance medications taken regularly over time. Some plans offer lower cost sharing for certain drugs through mail order.
Maximum Benefit
The most a plan will pay for a specific service, category of care, or benefit period. Once that limit is reached, the member may be responsible for additional costs, depending on the plan.
Maximum Out-of-Pocket / Out-of-Pocket Maximum
The most a member pays in a plan year for covered services through deductibles, copays, and coinsurance. After that limit is reached, the plan generally pays 100% of covered services for the rest of the year.
Medical Necessity / Medically Necessary
Services or supplies a plan determines are appropriate and needed to diagnose or treat a condition, based on the plan’s standards.
Member ID Card
The insurance card a member uses to show proof of coverage when receiving care or filling prescriptions. It typically includes important details such as the member ID number, group number, and carrier contact information.
N
Network
The group of doctors, hospitals, pharmacies, and other providers a plan contracts with to deliver care at negotiated rates.
Non-Preferred Brand Drug
A brand-name prescription drug that is covered but placed in a higher-cost tier than preferred drugs.
O
Observation Stay
Hospital-based monitoring used when a patient needs evaluation or short-term treatment but has not been formally admitted as an inpatient. Observation status can affect how services are billed and what the member may owe.
Open Enrollment
The annual period when eligible employees can enroll in coverage, change plans, or make certain benefits elections. Outside of open enrollment, changes are typically limited unless a qualifying event occurs.
Out-of-Network
Providers or facilities that do not have a contract with the health plan. Using them can result in higher costs and, in some cases, balance billing.
Out-of-Pocket Costs
The member’s health care expenses that are not reimbursed by insurance. These can include deductibles, coinsurance, copays, and costs for services that are not covered.
P
PCP (Primary Care Provider)
The doctor or clinician a member sees for routine care, preventive care, and general health concerns. Some plans also require a PCP to coordinate referrals to specialists.
PPO (Preferred Provider Organization)
A plan type that usually offers more flexibility to see providers inside or outside the network, though out-of-network care often costs more.
Premium
The amount paid for health coverage, usually every month. Premiums are separate from the costs a member pays when they actually receive care.
Preventive Care
Certain recommended services intended to help prevent illness or detect problems early. Under many plans, covered preventive services may be available without cost sharing when received from the right provider and billed correctly.
Provider
A doctor, hospital, clinic, pharmacy, therapist, or other licensed health care professional or facility delivering care.
Q
Qualifying Life Event
A life change, such as marriage, divorce, birth, adoption, or loss of other coverage, that may allow a person to make benefits changes outside the normal open enrollment period.
R
Referral
Approval or direction from a PCP or plan that allows a member to see a specialist or receive certain services. Referral requirements depend on the plan type.
Rx Tier
A prescription drug cost level within a plan’s formulary. Drugs are grouped into tiers, and each tier may have a different copay or coinsurance amount.
S
SBC (Summary of Benefits and Coverage)
A standard document plans must provide that summarizes covered services, cost sharing, and key plan features in a uniform format.
Self-Funded vs. Fully Insured
A self-funded health plan is funded directly by the employer, though an insurance carrier or administrator may help manage claims and administration. A fully insured plan is purchased from an insurance carrier, which takes on the financial risk for paying claims.
Special Enrollment Period
A limited time outside open enrollment when a person can enroll in or change coverage because of a qualifying event or other eligibility trigger.
Specialist
A provider who focuses on a particular area of medicine, such as cardiology, dermatology, or orthopedics. Some plans require referrals before specialist visits.
Step Therapy
A rule that may require a member to try one medication before the plan will cover another.
U
Urgent Care
Care for a condition that needs prompt attention but is not a true emergency. Coverage and copays vary by plan and network.
Usual, Customary, and Reasonable (UCR)
A term sometimes used to describe the amount a plan considers appropriate for a medical service in a certain area. If a provider charges more than that amount, the member may be responsible for the difference, especially without-of-network care.
V
Virtual Care / Telehealth
Medical or behavioral health services provided remotely, often by video or phone, depending on the plan and provider arrangement.
W
Waiting Period
The amount of time an employee or dependent must wait before becoming eligible for coverage. Waiting periods are usually outlined by the employer’s benefit plan rules.
