Making Sense of Medicare Terms and Phrases

As you read more about Medicare plans, you'll see some of the same Medicare terms and phrases repeatedly. If you're not sure what those terms mean, this glossary will help.

ACTUAL CHARGE
The amount of money a doctor or supplier charges for a specific medical service or supply. Because Medicare and insurance companies usually negotiate lower rates for members, this amount is often greater than the "approved amount" that you and Medicare actually pay.
ANNUAL ELECTION PERIOD (AEP)
October 15 through December 7 of each year. Usually, this is the only time when Medicare Advantage health plans and Prescription Drug Plans are open and accepting new members, other than those who are newly eligible. Medicare Supplement plans are open for enrollment year-round if you meet certain requirements. See the definition for Medicare Supplement insurance.
BENEFICIARY
A person who has health insurance through the Medicare or Medicaid program.
BENEFITS
The services provided by an insurance policy. In a health plan, benefits are the health care services you receive, such as doctors' office visits, prescription drug coverage, etc.
CATASTROPHIC ILLNESS
A very serious and costly health problem that could be life threatening or cause life-long disability. The cost of medical services for this type of condition could cause you financial hardship if you are not properly insured.
CENTERS FOR MEDICARE & MEDICAID SERVICES (CMS)
The federal agency that runs the Medicare program. In addition, CMS works with the states to run the Medicaid program. CMS works to make sure that the beneficiaries in these programs are able to get high-quality health care.
COINSURANCE
The percentage of billed charges that you may have to pay after you pay any plan deductibles. The coinsurance payment is a percentage of the cost of the service. For instance, your health plan might pay 70 percent of billed charges; hence, your coinsurance payment is the remaining 30 percent.
COPAYMENT
The flat amount you pay to a health care provider or pharmacy at the time of service. Copayments vary depending on your plan and the services you receive. Copayments do not reduce your annual deductible.
DEDUCTIBLE
The total amount you must pay for health care before your health plan begins to pay.
DUAL ELIGIBLES
Persons who are entitled to Medicare and also eligible for Medicaid.
EFFECTIVE DATE
The date your coverage begins.
EMERGENCY CARE
Covered services that are 1) furnished by a provider qualified to furnish emergency services; and 2) needed to evaluate or stabilize an emergency medical condition.

IN-NETWORK PROVIDER
A health care provider – such as a doctor, hospital, other medical facility, or pharmacy – that has agreed to charge a set rate for members of a health benefits plan. Providers on the list of network members are also called participating providers. Your network choices may vary, depending on your plan and where you live.
LIMITATIONS
Items or services a health plan doesn't cover in some circumstances.
LOCK-IN PERIOD

MAXIMUM ENROLLEE OUT-OF-POCKET COSTS
The maximum dollar amount you would be required to pay out of your own pocket for health services during a specified period of time.
MAXIMUM PLAN BENEFIT COVERAGE

Medicare Advantage Organizations can offer one or more Medicare Advantage plans. CarePlus Health Plans, Inc. is a Medicare Advantage Organization.
MEDICARE ADVANTAGE PREFERRED PROVIDER ORGANIZATION (PPO) PLAN
A Medicare Advantage PPO gives you two ways to receive medical services. You can use doctors and hospitals inside the network and pay less for your care. Or you have the option of going outside the network, but you will pay more for your health care services. Each time you need care, the choice is yours.
MEDICARE ADVANTAGE PRIVATE-FEE-FOR-SERVICE (PFFS) PLAN

MEDICARE SUPPLEMENT INSURANCE
A policy sold by a private insurance company that helps cover the "gaps" in coverage that are left unpaid after Original Medicare pays its portion of your health care expenses. For this reason, these plans are often called "Medigap" plans. Medicare Supplement policies pay only for services Medicare considers medically necessary. Payments are generally based on the Medicare-approved charge. The policy might not fully cover all of your medical costs.
NETWORK
A group of doctors, hospitals, and pharmacies who have contracts with an insurance plan to provide care to the plan's members. Your network choices may vary, depending on your plan and where you live.

ORIGINAL MEDICARE
A plan that is available everywhere in the United States. Some people call it "traditional Medicare" or "fee-for-service" Medicare. Original Medicare is the way most people get their Medicare Part A and Part B health care. It is the national pay-per-visit program that lets you go to any doctor, hospital, or other health care provider who accepts Medicare. You must pay the deductible. Medicare pays its share of the Medicare-approved amount, and you pay your share. Original Medicare has two parts: Part A (Hospital Insurance) and Part B (Medical Insurance).
OUT-OF-NETWORK BENEFIT
Generally, an out-of-network benefit gives you the option to use a doctor, specialist, or hospital that is not a part of the plan's contracted network. In some cases, your out-of-pocket costs may be higher for an out-of-network benefit.

OUTPATIENT CARE
Medical or surgical care that does not include an overnight hospital stay.

PRIMARY CARE PROVIDER (PCP)
A health care professional who is trained to give you basic care. Your PCP is responsible for providing or authorizing covered services while you are a plan member.
PROVIDER
A person or facility that offers health care services. For example, a doctor, hospital, skilled nursing facility, home health agency, outpatient physical therapy, comprehensive outpatient rehabilitation facility, End-Stage Renal Disease facility, hospice, non-physician provider, laboratory, supplier, etc. A provider is licensed or certified and practices within the scope of his or her license or certification.
REFERRAL
A written request from your Primary Care Provider for you to see a specialist or to receive certain services.
SERVICE AREA
The geographic area in which a health plan accepts members. For Medicare plans that require you to use participating doctors and hospitals, it is also the area where services are provided. The plan may disenroll you if you move out of the plan's service area.
SPECIAL ELECTION PERIOD (Medicare Advantage Plans)

A set time that a beneficiary can change health plans or return to Original Medicare due to a qualifying event. Examples of special election situations are:
