Term	Definition
ACTUARIAL EQUIVALENT	A plan sponsor must offer a prescription drug plan that is actuarially (a term relating to the statistical calculation of risk) the same or better than the Medicare Part D prescription drug plan
ANY WILLING DOCTOR	A doctor, hospital, or other health care provider that agrees to accept the plan's terms and conditions related to payment and that meets other requirements for coverage.
APPEAL	A special kind of complaint you make if you disagree with certain kinds of decisions made by Original Medicare or by your health plan. You can appeal if you request a health care service, supply or prescription that you think you should be able to get from your health plan, or you request payment for health care you already received, and Medicare or the health plan denies the request. You can also appeal if you are already receiving coverage and Medicare or the plan stops paying. There are specific processes your Medicare Advantage Plan, other Medicare Health Plan, Medicare drug plan, or the Original Medicare plan must use when you ask for an appeal.
ASSIGNMENT	In the Original Medicare Plan, this means a doctor or supplier agrees to accept the Medicare-approved amount as full payment. If you are in the Original Medicare Plan, it can save you money if your doctor accepts assignment. You still pay your share of the cost of the doctor's visit.
AUTHORIZATION	MCO approval necessary prior to the receipt of care. (Generally, this is different from a referral in that, an authorization can be a verbal or written approval from the MCO whereas a referral is generally a written document that must be received by a doctor before giving care to the beneficiary.)
